Question
Nitrogen dioxide is a gas commonly found in polluted air. It is produced when nitric oxide in the air reacts with oxygen gas.
Consider the following reaction:
20 molecules of nitric oxide (NO) react with 10 molecules of oxygen (O2) to produce some amount of nitrogen dioxide (NO2).
Complete the table below.
Chemical element Number of atoms in the reaction
N
O
During this reaction, how many molecules of nitrogen dioxide (NO2) are produced?

Count atoms:
- N: 20 (one N per NO × 20)
- O: 40 (one O per NO × 20 = 20, plus two O per O2 × 10 = 20; total 40)
Each NO2 has 1 N and 2 O, so the atoms form 20 NO2 molecules. (Balanced equation: 20 NO + 10 O2 → 20 NO2.)
