Final answer:
To balance the equation N2 + O2 -> 2 NO, we can see that the coefficients are already balanced for the nitrogen atoms. However, we need to balance the oxygen atoms. The product contains 5 atoms of nitrogen and 10 atoms of oxygen.
Step-by-step explanation:
To balance the equation N2 + O2 -> 2 NO, we can see that the coefficients are already balanced for the nitrogen atoms. However, we need to balance the oxygen atoms. Since there are 10 oxygen atoms on the left side of the equation (5 O2 molecules) and only 2 oxygen atoms on the right side (in the 2 NO molecules), we need to multiply the NO by 5 to get 10 oxygen atoms on the right side:
N2 + O2 -> 5 NO
Therefore, in the product, there are 5 atoms of nitrogen and 10 atoms of oxygen.
