To balance the skeleton equation \( \text{NO} \rightarrow \text{N}_2 + \text{O}_2 \), we need to ensure that the number of each type of atom on the reactant side equals the number on the product side.

  1. Counting atoms in the unbalanced equation:

    • Reactants:
      • 1 Nitrogen (N) from NO
      • 1 Oxygen (O) from NO
    • Products:
      • 2 Nitrogens (N) from N₂
      • 2 Oxygens (O) from O₂

  2. Balancing Nitrogen: To balance Nitrogen, we put a coefficient of 2 in front of NO: \[ 2 \text{NO} \rightarrow \text{N}_2 + \text{O}_2 \]

  3. Counting atoms again:

    • Reactants:
      • 2 Nitrogens (N)
      • 2 Oxygens (O)
    • Products:
      • 2 Nitrogens (N)
      • 2 Oxygens (O)

  4. Final balanced equation: \[ 2 \text{NO} \rightarrow 1 \text{N}_2 + 1 \text{O}_2 \]

Thus, the coefficients that balance the equation are 2, 1, 1.

So the correct response is: 2, 1, 1.
