Balance each given chemical reaction: Ca3N2(s) + H2O(aq) → Ca(OH)2(aq) + NH3(g)

To balance the given chemical reaction, follow these steps:

1. Write down the unbalanced equation: Ca3N2(s) + H2O(aq) → Ca(OH)2(aq) + NH3(g)

2. Balance the equation for the metal first (Calcium, Ca). There are 3 Ca atoms on the left side and only 1 on the right side. To balance this, put a coefficient of 3 in front of Ca(OH)2 on the right side: Ca3N2(s) + H2O(aq) → 3Ca(OH)2(aq) + NH3(g)

3. Next, balance the equation for Nitrogen (N). There are 2 N atoms on the left side and only 1 on the right side. To balance this, put a coefficient of 2 in front of NH3 on the right side: Ca3N2(s) + H2O(aq) → 3Ca(OH)2(aq) + 2NH3(g)

4. Now, balance the equation for Hydrogen (H). There are 2 H atoms on the left side and 14 on the right side (6 from 3Ca(OH)2 and 6 from 2NH3). To balance this, put a coefficient of 6 in front of H2O on the left side: Ca3N2(s) + 6H2O(aq) → 3Ca(OH)2(aq) + 2NH3(g)

5. Finally, balance the equation for Oxygen (O). There are 6 O atoms on the left side and 6 on the right side, so it's already balanced.

So, the balanced chemical equation is: Ca3N2(s) + 6H2O(aq) → 3Ca(OH)2(aq) + 2NH3(g)
