Problem 3.66 Calcium hydride reacts with water to form calcium hydroxide and hydrogen gas. (a) Write a balanced chemical equation for the reaction.(b) How many grams of calcium hydride are needed to form 4.500 g of hydrogen?
Step-by-Step Solution:

Step 1 of 5) Oxidation is the loss of electrons by a substance, whereas reduction is the gain of electrons by a substance. Oxidation numbers keep track of electrons during chemical reactions and are assigned to atoms using specific rules. The oxidation of an element results in an increase in its oxidation number, whereas reduction is accompanied by a decrease in oxidation number. Oxidation is always accompanied by reduction, giving oxidation-reduction, or redox, reactions.Many metals are oxidized by O2, acids, and salts. The redox reactions between metals and acids as well as those between metals and salts are called displacement reactions. The products of these displacement reactions are always an element 1H2 or a metal) and a salt. Comparing such reactions allows us to rank metals according to their ease of oxidation. A list of metals arranged in order of decreasing ease of oxidation is called an activity series. Any metal on the list can be oxidized by ions of metals 1or H+2 below it in the series.
