The Chemistry Book

Unit 5

Unit 5 is California content standards 5, 8, and 9.

Featured Articles Students interested in earning credit by editing articles should start with the featured articles. Article #1 Chemical Reactions involve the chemical changes of reactants. Chemists find it easier to describe these reactions by grouping common features. read more and edit   Article #2 Le Chatelier's Principle is used to predict the effect of a change in conditions on a chemical equilibrium. Henri Le Chatelier suggested that when a system at equilibrium is disturbed, the equilibrium position will shift in the direction which tends to minimize, or counteract, the effect of the disturbance.
