These answers are for the following sections: Section 21.1 Electrochemical Cells Part A-D pp. 543-544; Section 21.2 Half-cells and Cell Potentials Part A-D pp. 545-546; and Section 21 Electrochemistry Vocabulary Review p. 552.<br /><br />For Section 21.2 Practice Problems on page 549, we went over it as a class. We were assigned in pairs to each answer questions on the board. Unfortunately, I was not able to write down any of the answers (I didn't know I was scribing today. Otherwise, I would've!).<br /><br />But that was pretty much it for the entire period. It was basically just a review/study period for our "sweet little test" tomorrow according to Mrs. K!<br /><br />Well, that's it for today. Make sure to study for tomorrow's test. Good luck everyone!<br /></span></span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4589527844468506642-2229275859596442612?l=dmcichem120409.blogspot.com' alt='' /></div>itscaaandynoreply@blogger.com0tag:blogger.com,1999:blog-4589527844468506642.post-17505996643889390402009-06-04T13:15:00.001-05:002009-06-04T13:15:32.469-05:00<div style="width:425px;text-align:left" id="__ss_1534137"><a style="font:14px Helvetica,Arial,Sans-serif;display:block;margin:12px 0 3px 0;text-decoration:underline;" href="http://www.slideshare.net/ekozoriz/ch-21-review?type=presentation" title="Ch 21 Review">Ch 21 Review</a><object style="margin:0px" width="425" height="355"><param name="movie" value="http://static.slidesharecdn.com/swf/ssplayer2.swf?doc=ch21review-090604124128-phpapp01&stripped_title=ch-21-review" /><param name="allowFullScreen" value="true"/><param name="allowScriptAccess" value="always"/><embed src="http://static.slidesharecdn.com/swf/ssplayer2.swf?doc=ch21review-090604124128-phpapp01&stripped_title=ch-21-review" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="355"></embed></object><div style="font-size:11px;font-family:tahoma,arial;height:26px;padding-top:2px;">View more <a style="text-decoration:underline;" href="http://www.slideshare.net/">Microsoft Word documents</a> from <a style="text-decoration:underline;" href="http://www.slideshare.net/ekozoriz">ekozoriz</a>.</div></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4589527844468506642-1750599664388939040?l=dmcichem120409.blogspot.com' alt='' /></div>Ms Khttp://www.blogger.com/profile/04392731860936228950noreply@blogger.com0tag:blogger.com,1999:blog-4589527844468506642.post-27579739087043498152009-06-04T08:45:00.005-05:002009-06-04T11:10:07.867-05:00Mrs.K posted the assignment 4 worksheet that we corrected together, after we finished with that we were told to work on assignment 4 question 5 and hand it in at the end of class for marks, so whoever missed class they missed out on marks. She also handed back the lab (activity of metals) which we apparently all bombed. We also got the review for electrochemical cells which we are going to go over on thursday, aka today. So i think that i covered everything we did in class so the next scribe will be .........

we did today was go over chapter 19 study guide. We had approximately twenty minutes to work on it in class, and then Mrs. k went over it. The study guide is composed of acid and bases questions, which is basically the review for our upcoming test. <br /><br /> For people who are looking for the study guide answers do not worry, Mrs k will upload soon enough on the blog .<br /><br />Test on Monday 25, so use your weekend wisely and hopefully you'll ace the test.<br /><br />Next scribe is.... is .....

this is Robel. My first time blogging and i'll try to make it as exciting as possible. As usual Mrs. k began teaching the second we got into class. She went over questions Acid-Base work sheet 4 numbers 1 -4.

K handed us RELATIVE STRENGTHS OF ACIDS and ACID DISSOCIATION CONSTANT. On the second worksheet we learned the difference between Ka and Kb. </span><br /><span style="font-size:85%;"></span><br /><span style="font-size:85%;"><strong>Ka</strong> is the acid dissociation constant or ionization constant. The larger the Ka, the stronger the acid and therefore there's more product and thats there's greater dissociation. The smaller the Ka, the less the product and therefore weaker acid.</span><br /><span style="font-size:85%;"></span><br /><span style="font-size:85%;"><strong>Kb </strong>is the base dissociation constant. It reflects the strength of a base. the higher the base, the higher the value of Kb will be.</span><br /><span style="font-size:85%;"></span><br /><span style="font-size:85%;">We also went over how to CALCULATE THE DISSOCIATION CONSTANT. Its almost the same as how to calculate the equilibrium constant, by setting up an ic table. Also, Ka and Kb has no units, just like Kc.</span><br /><span style="font-size:85%;"></span><br /><span style="font-size:85%;">LAB IS DUE TODAY.</span><br /><span style="font-size:85%;"></span><br /><span style="font-size:85%;">the next scribe is LARLYN:))</span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4589527844468506642-8144899480504415492?l=dmcichem120409.blogspot.com' alt='' /></div>mayikenhttp://www.blogger.com/profile/14879053329858890031noreply@blogger.com0tag:blogger.com,1999:blog-4589527844468506642.post-28362483609541266212009-05-12T11:17:00.000-05:002009-05-12T11:18:03.306-05:00<div style="width:425px;text-align:left" id="__ss_1423644"><a style="font:14px Helvetica,Arial,Sans-serif;display:block;margin:12px 0 3px 0;text-decoration:underline;" href="http://www.slideshare.net/ekozoriz/ph-questions?type=powerpoint" title="pH Questions">pH Questions</a><object style="margin:0px" width="425" height="355"><param name="movie" value="http://static.slidesharecdn.com/swf/ssplayer2.swf?doc=phquestions-090512111131-phpapp01&stripped_title=ph-questions" /><param name="allowFullScreen" value="true"/><param name="allowScriptAccess" value="always"/><embed src="http://static.slidesharecdn.com/swf/ssplayer2.swf?doc=phquestions-090512111131-phpapp01&stripped_title=ph-questions" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="355"></embed></object><div style="font-size:11px;font-family:tahoma,arial;height:26px;padding-top:2px;">View more <a style="text-decoration:underline;" href="http://www.slideshare.net/">presentations</a> from <a style="text-decoration:underline;" href="http://www.slideshare.net/ekozoriz">ekozoriz</a>.</div></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4589527844468506642-2836248360954126621?l=dmcichem120409.blogspot.com' alt='' /></div>Ms Khttp://www.blogger.com/profile/04392731860936228950noreply@blogger.com0tag:blogger.com,1999:blog-4589527844468506642.post-51443500699041153512009-05-11T22:29:00.006-05:002009-05-12T22:36:43.885-05:00<span style="font-family:trebuchet ms;">Today, we learned/recalled that we can determine the </span><span style="color: rgb(204, 0, 0); font-weight: bold;font-family:trebuchet ms;" >acidity </span><span style="font-family:trebuchet ms;">or </span><span style="color: rgb(51, 102, 255); font-weight: bold;font-family:trebuchet ms;" >alkalinity </span><span style="font-family:trebuchet ms;">of an aqueous solution by different indicators.</span><br /><br /><br /><span style="font-family:trebuchet ms;"> 1. </span><span style="color: rgb(204, 51, 204); font-weight: bold;font-family:trebuchet ms;" >The pH meter</span><span style="font-family:trebuchet ms;"> - It is an electronic device that shows a numerical value of how acidic or basic a solution is.

The sheet is called <span style="font-style: italic;">An Analogy for an Equilibrium Reaction</span>. The purpose of the lab was to help familiarize us with a system in equilibrium and how certain conditions effect that system. We were allowed to share data but everyone must hand in their own lab.<br /><br /><span style="color: rgb(0, 102, 0);">The experiment:</span><br />First we had to transfer water from one cylinder to another by using straws then record the change in volume in each cylinder. This was repeated for three transfers until the data remained the same. Once this happened we had to had an additional 5ml to ONE of the cylinders (A) then repeated until we reached the point where three transfers gave the same data.<br /><br />For the data a chart is required to record the <span style="font-style: italic;">number of transfers, volume of cylinder A, and volume of cylinder B</span>. Next we had to plot the data on graph paper and answer the questions that followed.

The system is not actually stopping but always moving constantly showing a constant opposition. </em><br /><br /><strong><span style="color:#ff0000;">Physical Equilibrium</span> </strong>- <em>A reversible physical process is where the rate of forward is equal to the rate of reverse.</em><br /><br /><em>**** Keep note the only time a reversible reaction can be in equalibrium is in a closed system**** "closed systems keep particles in and other particles to stay out. A form of consistency is shown between the particles eg. <span style="color:#ff0000;">vapor vs condensation</span> </em><br /><br /><em>****Equilibriums by the way look/seem unmoving but they actually are in motion****</em><br /><br /><strong>Equilibrium law and Equilibrium Constant</strong> - Known as the <em>Law of mass action/Equilibrium law </em>by Cato Goldberg and Peter Waage in 1864. <em>The Equilibrium law</em> is suggested to be a ratio between the concentrations of the products to the reactants.<br />A value is then given from the ratios and this numerical value is the <em>Equilibrium Constant</em><br /><br />(Ok enough of the definitions now onto some real work! *raises sleeves up to shoulder length*)<br /><br />****Keep note if Kc/Equalibrium constant what the value is equal to; this value determines either the reactants/products being favored in which<br />this is as follows: <em><span style="color:#ff0000;">Kc = 1 reactants &amp; products neither favored </span></em><br /><em><span style="color:#ff0000;"> Kc = more than 1; products concentration greater and is favored </span></em><br /><em><span style="color:#ff0000;"> Kc = less than 1; reactants concentration greater and is favored</span></em><br /><em><span style="color:#ff0000;"></span></em><br /><br />I'll just head onto showing you how to get Equalibrium Concentrations since that part was from yesturday and it seems like we should note it<br /><em>(Getting the Kc should be no problem but if you don't remember just ask around!)</em><br /><br />We have info:<br />Set up an ICE table (ICE is abbriviated in to Intial concentration(I), Delta"change in" Concentrations(C) and equilibruim concentrations (E)<br /><br />for example we are given 2 reactants with equal moles<br /><br />I 2.00 2.00 0<br /><br />C -x -x +2x<br /><br />E 2 - x 2 - x 2x<br /><br /><br />Ill get into detail with this if you want later time is of an essense<br /><br />Niwatori-san signing off---><br /><br />Next Scribe is miss Kayla! =D<br /><br />*passes baton and then skoots away*<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4589527844468506642-5994311183868151675?l=dmcichem120409.blogspot.com' alt='' /></div>Niwatori-sanhttp://www.blogger.com/profile/04592387745767050810noreply@blogger.com0tag:blogger.com,1999:blog-4589527844468506642.post-67504575042215880072009-04-15T11:08:00.000-05:002009-04-15T11:09:38.229-05:00<div style="width:425px;text-align:left" id="__ss_1294444"><a style="font:14px Helvetica,Arial,Sans-serif;display:block;margin:12px 0 3px 0;text-decoration:underline;" href="http://www.slideshare.net/ekozoriz/equilibrium-problems1?type=presentation" title="Equilibrium Problems1">Equilibrium Problems1</a><object style="margin:0px" width="425" height="355"><param name="movie" value="http://static.slidesharecdn.com/swf/ssplayer2.swf?doc=equilibriumproblems1-090415110137-phpapp01&stripped_title=equilibrium-problems1" /><param name="allowFullScreen" value="true"/><param name="allowScriptAccess" value="always"/><embed src="http://static.slidesharecdn.com/swf/ssplayer2.swf?doc=equilibriumproblems1-090415110137-phpapp01&stripped_title=equilibrium-problems1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="355"></embed></object><div style="font-size:11px;font-family:tahoma,arial;height:26px;padding-top:2px;">View more <a style="text-decoration:underline;" href="http://www.slideshare.net/">presentations</a> from <a style="text-decoration:underline;" href="http://www.slideshare.net/ekozoriz">ekozoriz</a>.</div></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4589527844468506642-6750457504221588007?l=dmcichem120409.blogspot.com' alt='' /></div>Ms Khttp://www.blogger.com/profile/04392731860936228950noreply@blogger.com0tag:blogger.com,1999:blog-4589527844468506642.post-47290764377238008522009-04-14T09:30:00.003-05:002009-04-15T11:10:30.082-05:00Seeing how Moffatt didn't blog, I'll take do it for him.

I speak for the majority of the class when I say I am lost in this unit.<br />Lately substitutes have been filling in but to no prevail have I learned anything because everything was just written on the board and was assumed that I knew what was being wrote.<br /><br />So I'm asking on behalf of the class if Mrs. Kozoriz postpones the test till let's say, Thursday or Friday because we need some INSANE review.<br /><br />Oh and get well soon Mrs. Kozoriz.<div class="blogger-post-footer"><img width='1' height='1'

Each of the group 1A elements has one electron in its highest energy level; each elements has one valence electron.This is no coincidence. The group 1A elements have similar chemical properties because they all have the same number of valence electron configuration of s1. Like wise, each group 2A elements has a valence electron configuration of s2.</span> Tomorrow's scribe is Yonas<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4589527844468506642-8162589746958768038?l=dmcichem120409.blogspot.com' alt='' /></div>Ahmedhttp://www.blogger.com/profile/01505091746305151687noreply@blogger.com0tag:blogger.com,1999:blog-4589527844468506642.post-47480564083025334392009-03-12T11:29:00.001-05:002009-03-12T11:29:40.230-05:00<div style="width:425px;text-align:left" id="__ss_1136922"><a style="font:14px Helvetica,Arial,Sans-serif;display:block;margin:12px 0 3px 0;text-decoration:underline;" href="http://www.slideshare.net/ekozoriz/ec-1136922?type=powerpoint" title="Ec">Ec</a><object style="margin:0px" width="425" height="355"><param name="movie" value="http://static.slideshare.net/swf/ssplayer2.swf?doc=ec-090312110503-phpapp02&stripped_title=ec-1136922" /><param name="allowFullScreen" value="true"/><param name="allowScriptAccess" value="always"/><embed src="http://static.slideshare.net/swf/ssplayer2.swf?doc=ec-090312110503-phpapp02&stripped_title=ec-1136922" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="355"></embed></object><div style="font-size:11px;font-family:tahoma,arial;height:26px;padding-top:2px;">View more <a style="text-decoration:underline;" href="http://www.slideshare.net/">presentations</a> from <a style="text-decoration:underline;" href="http://www.slideshare.net/ekozoriz">ekozoriz</a>.</div></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4589527844468506642-4748056408302533439?l=dmcichem120409.blogspot.com' alt='' /></div>Ms Khttp://www.blogger.com/profile/04392731860936228950noreply@blogger.com0tag:blogger.com,1999:blog-4589527844468506642.post-66023130127151052672009-03-10T17:12:00.004-05:002009-03-11T08:40:34.404-05:00TODAY'S CLASS:<br /><br />Ms. K read through the GR 12 CHEMISTRY Atomic Structure: ELECTRON CONFIGURATIONS handout.<br /><br />Introduced in the handout was electron configuration, being the arrangement of electrons in an atom. Atom's always want to be in their lowest-energy system possible, to remain most stable. The three rules/principles of how orbitals are filled are:<br /><br />a) The Aufbau principle<br />- which states that each electron fills the lowest energy orbital available. For example, the aufbau diagram shows how the energy increases from 1s, 2s, 2p,3s,3p and so on.<br /><br />b) The Pauli exclusion principle<br />- which states that a maximum of two electrons may occupy an orbital, but only if the electrons have opposite spins. The opposite spins are represented by two arrows, one pointing up, and the other pointing down.<br /><br />c) Hund's rule<br />- which states that single electrons with the same spin must sit in each equal orbital before electrons with opposite spins can fill the same orbitals.<br /><br />We also learned how to use a sublevel diagram, which will help when remembering how to fill orbitals. It is on page 2 of the handout, or uploaded below.<br /><br />We were then assigned the 'Problems on Electron Configurations' on the back page.<br /><br />I hope I blogged properly!

I forgot, but anywho, we got our tests back for the redox test thingy majiggy. Anyways, after we went over the test, we started the spectrum unit thingy. Apparently, there are a bunch of atoms that have like, certain colors and stuff... And something about the number 590 and 600 etc. We got a sheet teaching us how to make dangerous explosives (fireworks) and some more sheets and stuff about the spectrum and colors and elements and their colors and stuff.<br />So then like, we did this other thingy, where misses teacher dude had like, this machine that makes things glow. We got these wicked sick glasses, temporarily, and used them to look at the machine which made electrons fly around inside the gas tubes, causing the atoms to get 'excited' and emit a light (chemiluminecense I believe it is called). So first we did like, Hydrogen. Hydrogen had a really cool colour thingy to it, and with the glasses you can see three lines, Red, Blue, Teal, coming from the farther away side of the atom-exciter-machine to the inwards direction (that DOES make sense). And then we looked at Helium, which was Red Orange Green and Blue, and then Iodine, which was, like, pretty much the colour of the rainbow... (ROYGBiV).<br />Okay so then umm... misses teacher dude decided to try some more but they didn't work. So that was a fail. <br />So the uhh...... sheets we got from misses teacher dude were this one sheet, about atomic structure assignment 1..... that's what it's called.... and then another sheet, which looks like a chart for spectral lines of elements, and then yet another sheet, which we were to try and fill out while looking at the atom-exciter-machine, and yet another sheet titled : The Electromagnetic Spectrum, and then a Booklet regarding The Electromagnetic Spectrum of doom (this booklet contains instructions and ingredients for making a home-made fireworks thingy).

The Lab was called, "<strong>Titration Lab.</strong>"<br /><ul><li>What we did was we measured out 1.0 mL of distilled water into a 10 mL graduated cylinder. Must repeat 3 times to get an accurate result.</li><li>After that was done, we had to measure out 5 mL of distilled water into the graduated cylinder and then place that amount into a 50 mL beaker. And after we added a <strong>DROP </strong>of <strong>PHENOLPHTHALEIN INDICATOR.</strong> And swirled it a bit.</li><li>Next we took <strong>H</strong><span style="font-size:85%;">2</span><strong>SO</strong><span style="font-size:85%;">4</span> (<strong>SULFURIC ACID</strong>) and added <strong>20 DROPS </strong>into the beaker and then transfered that solution into the graduated cylinder to measure the volume. Then we placed it back into the beaker.</li><li>Next we then took <strong>NaOH </strong>(<strong>SODIUM HYDROXIDE</strong>) and had to <strong>COUNT </strong>the <strong>NUMBER OF DROPS</strong> that made the solution in the beaker to a permant pink color.</li><li>Then we place that solution back in the graduated cylinder and measure the volume of that solution.</li><li>After that was done, we cleaned out the equipment and did that lab again 2 more times so we can get an accurate result</li><li>And after we cleaned out the equipment and cleaned up.</li></ul><p>And that was pretty much what we did in class today. No notes, no homework (unless you didn't finish the other assignments.), and that was all. =D</p><p>So the next scribe for tomorrow will be : KAYLA =D</p><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4589527844468506642-4199636648286154664?l=dmcichem120409.blogspot.com' alt='' /></div>rawra =)http://www.blogger.com/profile/16152648006138644710noreply@blogger.com0tag:blogger.com,1999:blog-4589527844468506642.post-54423134667841538262009-02-16T16:43:00.005-06:002009-02-17T11:45:51.164-06:00Hi~~o(*∩_∩*)o<br /><br />On friday we corrected page 9 the problems 1 to 9 . . .<br />Here the answers : . . .<br /> <br />1. NaOH + HNO3 NaNO3 + H2O<br /> mol NaOH = 0.20 mol /1 * 1 = 0.20 mol<br /><br />2. HCl + KOH H2O + KCl<br /> x (0.45 mol/L) = 25.0 mL (1.00 mol/L)<br /> x = 56 mL<br /><br />3. a) HCl + NaOH H2O + NaCl<br /> mol HCl = 0.20 mol / 1 * 1 = 0.20 mol<br /><br /> b) 2HCl + Ca(OH)2 2H2O + CaCl2<br /> mol HCl = 0.10 mol /1 * 2 = 0.20 mol<br /><br />4. HCl + NaOH H2O + NaCl<br /> 28.0 mL / 1000 = 0.028 L<br /> mol HCl = 0.028 L (1.00 mol/L) = 0.028 mol<br /> 20.0mL / 1000 = 0.020 L<br /> C NaOH = 0.028 mol / 0.020 L = 1.40 mol/L<br /><br />5. End point - when performing a tritration the standard is added until one drop permanently change the colour of indicator.<br /> <br /> Equivalence point - As the two solution are mixed, the system will reach a point at which the acid and base will have neutralized one another.<br /> - The point at which the number of mole of acid are equivalent to the number of moles of base.<br /><br />6. C NaOH = x (43.0 mL) = 32.0 mL (0.100 mol/L)<br /> x = 0.0744 mol/L<br /><br />7. C NaOH = x (40.0 mL) = 25.0 mL (0.120 mol/L)<br /> x = 0.075mol/L<br /><br />8. C KOH = x (50.0 mL) = 30.0 mL (0.250mol/L)<br /> x = 0.15 mol/L<br /><br />9. mol of acid = 25.0 mL / 1000 * 1.44 mol/L = 0.036 mol<br /> mol of base = 36.0 mL / 1000 * 2.00 mol / L =0.072 mol<br /> <br /> Acid must be diprotic ( the base has one OH ion molecules and twice as many moles of base are required to neutralize the acid) <br /><br />And don't forget to do the worksheet~~<br /><br />The next scribe Rawra <br /><br />o(*∩_∩*)o<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4589527844468506642-5442313466784153826?l=dmcichem120409.blogspot.com' alt='' /></div>yiconghttp://www.blogger.com/profile/11372077772007275476noreply@blogger.com0tag:blogger.com,1999:blog-4589527844468506642.post-86200534430804457242009-02-12T19:19:00.016-06:002009-02-13T06:58:11.904-06:00Hi...Classmates^_^<br /><br /><div><div><div><div><div><div><div><div><div>Yup..

Check here before you choose a scribe for tomorrow's class when it is your turn to do so.<br /><a href="http://chemdmci.blogspot.com/"></a><br /><table><tbody><tr><td width="150"><br />m;<br /></td><td width="150"><br />Night Hawk<br />yassir<br />BooM<br /></td><td><br />aldrin<br /></td></tr></tbody></table><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4589527844468506642-6918235950260566751?l=dmcichem120409.blogspot.com' alt='' /></div>Ms Khttp://www.blogger.com/profile/04392731860936228950noreply@blogger.com0
