Determine if the following equation is balanced:

Question

4NH3+6NO = 5N2+6H2O

Answer 1

To determine if the equation $4N{H}_3+6NO=5N_2+6H_{2}O$ is balanced, we need to count the number of atoms of each element on both sides of the equation.

Counting atoms on the left side:

• $N{H}_3$: There are 4 molecules of ammonia.
  • Nitrogen (N): $4\times 1=4$
  • Hydrogen (H): $4\times 3=12$
• $NO$: There are 6 molecules of nitric oxide.
  • Nitrogen (N): $6\times 1=6$
  • Oxygen (O): $6\times 1=6$

So, the total for the left side is:

• Nitrogen (N): $4+6=10$
• Hydrogen (H): $12$
• Oxygen (O): $6$

Counting atoms on the right side:

• $N_2$: There are 5 molecules of nitrogen gas.
  • Nitrogen (N): $5\times 2=10$
• $H_{2}O$: There are 6 molecules of water.
  • Hydrogen (H): $6\times 2=12$
  • Oxygen (O): $6\times 1=6$

So, the total for the right side is:

• Nitrogen (N): $10$
• Hydrogen (H): $12$
• Oxygen (O): $6$

Comparison of both sides:

• Nitrogen (N): $10$ (left) = $10$ (right)
• Hydrogen (H): $12$ (left) = $12$ (right)
• Oxygen (O): $6$ (left) = $6$ (right)

Since the number of each type of atom is the same on both sides, the equation is balanced.

The equation $4N{H}_3+6NO=5N_2+6H_{2}O$ is balanced.
