Stoichiometry

To find the percent yield of an element, you just divide the actual yield by the theoretical yield & multiply by 100

Stoichiometry

For Stoichiometry, you must convert substance A to moles, use the coefficients of A & B from the balanced equation, & then convert to moles of substance B.

Stoichiometry

Of all the units, I feel like this makes the most sense to me. I'm going to need to study pretty hard to keep my understanding, but I feel pretty confident.

Describing Chemical Reactions

Today we learned how to describe chemical reactions, by using complete and net ionic equations. I think I have an okay grasp on the concept, but I can see myself screwing it up with small errors. The method of solving these problems is fairly simple, but there is a lot of room to make simple mistakes, which is something I have a tendency of doing. I'm going to have to really review polyatomic ions and nomenclature to succeed in this unit.
