-Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices: (1) Oxidation and reduction are complementary processes that always occur together.
(2) For a system at chemical equilibrium, decreasing the concentration of a reactant will always shift the equilibrium to the right.
(3) The reactants in a combination reaction must be elements.

Question

Quizplus · Accepted Answer

(1) is false, as oxidation and reduction can occur independently. 
(2) is false, as it depends on the specific reaction and equilibrium constant. 
(3) is true, as a combination reaction involves the combination of two or more elements to form a compound. Therefore, only statement (3) is true, resulting in choice C.
