Answer:
moles reactant = 2, moles of products = 3
Explanation:
The reactants are on the left side of the equation. Although, energy (heat) is a reactant it will not factor into the calculation for moles. The coefficient is the number of moles for each substances. So for the reactant side NO would have 2 moles because the coefficient is 2. Using the same logic, NO on the product side will have 2 moles and O2 will be 1 mole. O2 has one mole because it is implied that you know anything multipled by one is the same number. So 1 mole of O2 is written as O2 and not 1 O2.
