Balancing Chemical Equation

To balance the chemical equation LiH + H2O = LiOH + H2, we need to ensure that the same number of each type of atom is present on both sides of the equation.

First, let's list the number of atoms for each element on both sides of the equation:

- Lithium (Li): 1 on the left, 1 on the right - Hydrogen (H): 1 (from LiH) + 2 (from H2O) on the left, 1 (from LiOH) + 2 (from H2) on the right - Oxygen (O): 1 (from H2O) on the left, 1 (from LiOH) on the right

To balance the equation, we can start by balancing the hydrogen atoms first, then balance the oxygen atoms, and finally balance the lithium atoms.

Balancing Steps

1. Balance the hydrogen atoms: - Add a coefficient of 2 in front of LiOH to balance the hydrogen atoms.

The equation becomes: LiH + H2O = 2LiOH + H2

2. Balance the oxygen atoms: - Since the oxygen atoms are already balanced, no further action is needed.

3. Balance the lithium atoms: - Add a coefficient of 2 in front of LiH to balance the lithium atoms.

The final balanced equation is: 2LiH + 2H2O = 2LiOH + H2

So, the balanced chemical equation for the reaction LiH + H2O = LiOH + H2 is 2LiH + 2H2O = 2LiOH + H2.
