What do we call the matter we MIX TOGETHER in order for a chemical reaction to take place? Reactants
What do we call the matter that has FORMED as a result of a chemical reaction? Products
What must happens to the atoms in order for a chemical reaction to take place? The atoms must COLLIDE
What do we call the links that hold atoms together? Chemical Bonds
