Question
- A. Carbon dioxide
- B. Sulfur dioxide
- C. Oxides of nitrogen
- D. Soot
Answer
The correct option is Oxides of nitrogen. Oxides of nitrogen is correct because it matches the pollutant source boundary required for Atmospheric pollutants from fuels.
Explanation
Oxides of nitrogen is the correct option. Focus on the named pollutant source and avoid mixing it with greenhouse-gas effects. This answer supports the approved objective: Distinguish carbon dioxide as a greenhouse gas from pollutants such as carbon monoxide, sulfur dioxide, oxides of nitrogen and particulates. In Atmospheric pollutants from fuels, a correct response must stay within Common atmospheric pollutants and their sources and avoid borrowing wording from a neighbouring atmospheric chemistry objective.
Common mistake
Confusing Carbon Dioxide with Pollutants
Students often confuse carbon dioxide, which is a greenhouse gas, with pollutants like carbon monoxide and sulfur dioxide.
Remember that carbon dioxide is classified as a greenhouse gas, while carbon monoxide, sulfur dioxide, and oxides of nitrogen are considered pollutants that can harm the environment and human health.
