Question
- A. Oxygen
- B. Carbon dioxide

- D. Hydrogen
Answer
The correct option is Nitrogen. This answer is correct because it matches the approved learning objective to recall air as a source of nitrogen for the Haber process. (Chemistry only) in the subtopic The Haber process.
Explanation
The correct option is Nitrogen. Nitrogen is correct because it directly supports the approved learning objective to recall air as a source of nitrogen for the Haber process. (Chemistry only). This belongs to the subtopic The Haber process within The Haber process and the use of NPK fertilisers, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from The Haber process.
Common mistake
Source of Nitrogen Confusion
Students often confuse air with nitrogen gas, thinking air is purely nitrogen.
Remember that air is a mixture of gases, with nitrogen being the main component but not the only one.
