Question

jason combines the two intermediate steps shown. n2(g) + o2(g)→2no(g) 2no(g)+o2(g)→2no2(g) which best describes what jason should do with the oxygen molecules? place two of them as products. place two of them as reactants. cancel them out because there is one in each equation. double them because there is one in each equation.

Explanation:

Step1: Identify reaction - types concept

In chemical reactions, when combining intermediate steps, we look at species that appear as products in one step and reactants in another. These are the species that can be cancelled out to get the overall reaction.

Step2: Analyze oxygen molecules

The oxygen molecules that are products in one step and reactants in another should be cancelled out to simplify the overall reaction mechanism.

Answer:

Cancel them out because there is one in each equation.
