Today in class Ms.K went over questions 2 a), b), and 4 (as shown below) from Solubility Equilibria Assignment #1. We were then told to complete and hand in questions 2 c) and d). Later on Ms.K told us we also had to finish questions 5, 6, 7, and 8 for tomorrow and she also added that our test on this unit will be on tuesday next week.
Next scribe is Megan.

Today at the beginning of class Ms.K went over the answers for the Redox Reactions Worksheet. After that we worked on Section 20.3 Balancing Redox Equations Questions 2. a-d ;HalfrxnmethodView more presentations from ekozoriz.
Today we learned that to balance a redox reactions you need to;
1. Write the oxidation numbers
2. Split the equation into two parts; oxidation and reduction
3. Add electrons to the correct sides of the equations
4. For acidic reactions add H2O and then H+ as needed
5. For basic reactions ad H2O then H+ and then OH- as needed
6. Make electrons from both reactions the same by multiplying the whole reaction
7. Add the two reactions together
8. Check that oxidation
After we finished that Ms.K assigned us Section 20.3 Balancing Redox Equations Question 3. a-f for homework and it should be done for tomorrow.
