Final answer:
The question seems to contain a mistake in the chemical formula H₂N₂, which doesn't exist. Assuming the correct substances are H₂ and N₂, none of the given options for the coefficients of the balanced chemical equation H₂ + N₂ + O₂ → NO are correct. The properly balanced equation should have coefficients of 2 (for N₂), 1 (for O₂), and 2 (for NO).
Step-by-step explanation:
The question involves balancing a chemical equation, where you are asked to find the coefficients for the reactants and products. The equation given is H₂ + N₂ + O₂ → NO. To balance this equation, you'll need to count the number of atoms of each element on both the reactant and product sides and then adjust the coefficients accordingly until you have the same number of each atom on both sides.
However, after closely reviewing the reactants provided (H₂N₂ + O₂), it appears there may be a discrepancy as there is no compound with the formula H₂N₂ (it's likely supposed to be H₂ and N₂ separately). Assuming the correct equation is H₂ + N₂ + O₂ → NO and after balancing, the correct answer isn't provided in the options A, B, C, and D because the balanced equation for the formation of NO from N₂ and O₂ is 2N₂ + O₂ → 2NO, which gives us coefficients of 2, 1, and 2, respectively for N₂, O₂, and NO.
