    Things you should know about not mentioned in the video:
    Know that transition metals require a number for instance CuSO4 would be copper 2 sulfate. Make sure you know what a pure compound is and a pure substance. Also make sure to know what dipoles are and if you have say 10g of C2H4 make sure you can figure out how many moles or grams you have of say carbon or hydrogen. Don't forget about sig figs and how to name acids. ate - ick, ite - ous. Make sure to remember how to identify aqueous solutions and solid solutions. There's videos to remember such as NAG SAG. There's also acronyms to remember strong acids and know that all strong bases have OH in their formula.

    Thank you so much! This should seriously help with my final tomorrow!!! I don't know if you are employed as a teacher, but you should be. You explain things really well--that is a quality that most teachers don't really have. They all just spit out info and tell their students to study. They work out practice problems without explaining them, it is pretty rough out there. Keep up the good work dude!

    For those wondering at 8, why he simply added 1 and 2 to them. It's because the concentration we are looking for is actually the concentration of H+ ions in the solution, but since there are two moles of H in the molecule we have to add that 2, on the other side since it's a base we have the OH- concentration, however since there is only on mole of OH, the coefficient in front of the m1v1 is well 1. Hope it makes sense, and that I am not mistaken hahaha.
