Night Before Exam
It's December 2 and today is my birthday. I'm spending over half of my night studying for this test. I'm studying every study material I have. I'm practicing every problem. I'm looking at videos and rereading all of my notes. I'm just trying every possible thing to do in order to study. Net Ionic equations for double replacement is super easy and I feel good about it because you just switch cations with anions. However net ionic equations for everything else just confuse me a little bit. Synthesis, decomp, single replacement, and combustion are redox reactions, for you need to use the oxidation rules. If there are two nonmetals then you have to look at the periodic table to see whos is on top of each other and the element on top is stronger than the element on the bottom. Acid and Base always produce water. A strong base are group 1 and 2 elements on the periodic table. A strong base has 2 or more oxygen's outweighing the hydrogen's. Also HBr and HCl are strong acids. Strong base/acids break apart in reactions completely. Today I did a rundown with all the rules that apply to every type of equation. I just hope all of my efforts pay off tomorrow!!!!!

Happy late birthday! It's too bad that you had to spend so much time studying on your birthday. I also spent a lot of time studying, I agree that the net ionic equations for the other reactions were hard.
ReplyDeleteEven though you had to spend most of your birthday night studying equations and rules, hopefully it payed off on the test today! I feel the same way about the double replacement, and I know for me the oxidations were the worst.
