Balancing chemical equations notes
... chemicals are combined together and what chemicals are made when a reaction occurs. The law of conservation of mass says that matter can neither be created nor destroyed, and this requires that all chemical reactions be balanced. Consider the following balanced equation: Cu (s) + 4 HNO3 (aq) Cu(NO ...

Catalysis
Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.
