Today we understood that the amount of matter on the reactant side has to be equal to the amount of matter on the product side. So if we have four atoms on the reactant side, then we must have four atoms on the product side as well, even though they are new substances. We will work on more of that tomorrow.
Tonight for homework we have thinksheet # 0836. The thinksheet presents a variety of situations and we must determine whether they are physical or chemical changes. Remember to use as many vocab words as possible. Also remember that there are two sides (front and back)! Argh!
