The metal reacts slowly with oxygen, water vapor, and nitrogen of the air to form a yellow coating of the oxide, hydroxide, and nitride. It burns in air or pure oxygen to form the oxide and reacts rapidly with warm water to produce hydrogen gas and calcium hydroxide.
Metal hydroxides decompose on heating to yield metal oxides and water. Sodium hydroxide (NaOH) decomposes to produce sodium oxide (Na 2 O) and water (H 2 O). 2 NaOH (s) Na 2 O (s) + H 2 O (g) Some unstable acids decompose to produce nonmetal
