Test

We had a test the other day and I don't really know how I did on it! I'm hoping I did better than my quiz because I studied a lot.

Stoichiometry

Stoichiometry sounds like an intimidating topic, but the definition isn't as complicated as you might think. It is defined as, the process of using a chemical equation to calculate the relative masses of reactants and products involved in a reaction. The balanced equation for a chemical reaction describes the stoichiometry of the reaction. You always start off with what is given, and then you work your way to find what is needed. There are multiple ways to solve these problems, and I like using the magic number method. The video below will show you how to do it!

Quiz

We had a quiz the other day and I wasn't prepared for everything on it! I read over the chapter, but I think watching videos over the materials helps a lot more. Some of the questions I did the work and got the answer, but I would do something silly, like subtract my answers and pick the wrong one. Hopefully for the test I don't make silly mistakes, because at this point, every point counts.

Lab

We did a lab the other day to test the reactions between different chemicals. There were three liquids we mixed with solid to test if they had a chemical reaction or not. The solids were silver, copper, calcium magnesium, lead, and zinc. The liquids were water, copper (II) sulfate, and silver nitrate.  Calcium reacted with every liquid and was very active.
