Calcium hydride reacts with water to form calcium hydroxide (aqueous) and hydrogen gas. Write a balanced chemical equation for t
DanielleElmas [232]

Answer:

CaH_2(s) +2H_2O(l) \rightarrow Ca(OH)_2 (aq) + 2H_2 (g)

Explanation:

CaH_2(s) +H_2O(l) \rightarrow Ca(OH)_2 (aq) + H_2 (g)

In this reaction, calcium is balanced in either side. No. of atoms of 'H' and 'O' are not balanced. To balance O atoms, multiply H_2O by 2. Now the reaction becomes:

CaH_2(s) +2H_2O(l) \rightarrow Ca(OH)_2 (aq) + H_2 (g)

Now, to balance H atoms, multiply H2 by 2.

CaH_2(s) +2H_2O(l) \rightarrow Ca(OH)_2 (aq) + 2H_2 (g)

Now, each element is balanced.
