Calcium hydride reacts with water to form calcium hydroxide (aqueous) and hydrogen gas. write a balanced chemical equation for the reaction. express your answer as a balanced chemical equation. identify all of the phases in your answer.

Explanation:

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

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

Now, each element is balanced.

indium, and thallium have three electrons i think

the answer is b. dilution
