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.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
