Answer

a) $CaH_2+2H_2O \rightarrow Ca(OH)_2+2H_2$ b) $AlH_3+3H_2O \rightarrow Al(OH)_3+3H_2$ c) $NaH+H_2O \rightarrow NaOH+H_2$

Work Step by Step

When metal hydrides react with water, hydrogen is obtained: a) $CaH_2+2H_2O \rightarrow Ca(OH)_2+2H_2$ b) $AlH_3+3H_2O \rightarrow Al(OH)_3+3H_2$ c) $NaH+H_2O \rightarrow NaOH+H_2$
