Balance the following equations
`Ca+N_2 to Ca_3N_2`

Explanation

To balance the chemical equation for the reaction of calcium (Ca) with nitrogen (N₂) to form calcium nitride (Ca₃N₂), we can follow these steps:

### Step 1: Write the unbalanced equation
The unbalanced equation is:
\[ \text{Ca} + \text{N}_2 \rightarrow \text{Ca}_3\text{N}_2 \]

### Step 2: Count the number of atoms on each side
- On the left side (reactants):
