Question

Nitrogen monoxide and oxygen react to form nitrogen dioxide. consider the mixture of no and o2 shown in the accompanying diagram. the blue spheres represent n , and the red ones represent o . how many molecules of no2 can be formed, assuming the reaction goes to completion?

Answer 1

The number of molecules of NO₂ formed will be equal to the number of molecules of NO present in the mixture.

Step-by-step explanation:

According to the balanced chemical equation:

N₂(g) + O₂(g) → 2 NO(g)

For every 1 molecule of nitrogen monoxide (NO) formed, 1 molecule of nitrogen dioxide (NO₂) is also formed. This means that for every 2 molecules of nitrogen monoxide, 2 molecules of nitrogen dioxide will be formed.

Therefore, if the reaction goes to completion, the number of molecules of NO₂ formed will be equal to the number of molecules of NO present in the mixture.
