jason combines the two intermediate steps shown.\nn₂(g)+o₂(g)→2no(g)\n2no(g)+o₂(g)→2no₂(g)\nwhich best describes what jason should do with the oxygen molecules?\nplace two of them as products.\nplace two of them as reactants.\ncancel them out because there is one in each equation.\ndouble them because there is one in each equation.
Answer
Brief Explanations:
When combining chemical - reaction equations, we look at species that appear on both sides. Here, NO is an intermediate. The oxygen molecules ($O_2$) are reactants in both equations. When combining the two reactions $N_2(g)+O_2(g)\rightarrow2NO(g)$ and $2NO(g)+O_2(g)\rightarrow2NO_2(g)$, we add the reactants together and the products together. So, we place two of the oxygen molecules as reactants in the combined reaction.
Answer:
Place two of them as reactants.
