Thanks for the video, but I found it to be awfully quiet. I also wrote some quick notes for each question, might help others reviewing.

1. Pay attention to units
2. Don't use stoich when it's not needed
3. Make sure to read the question carefully because I thought it was looking for the excess reactant in both columns
4. d is obv incorrect, and a + b mean the same thing thus c is correct
5. protons are pos and electrons are neg, protons are more important when determining a neutrons so will be listed
6. ionization vs electron affinity
7. process of elimination
8. see 7
9. break the question up and solve each piece separately
10. Smarty guess by looking for common themes in the question, a+c+d all state absorbed and a+b both have d orbital to higher energy
