Question
- A. Nitrogen and hydrogen
- B. Oxygen and hydrogen
- C. Nitrogen and chlorine
- D. Ammonia and carbon dioxide
Answer
Nitrogen and hydrogen is correct: the Haber process combines nitrogen from air with hydrogen, usually obtained from natural gas and steam, to manufacture ammonia.
Explanation
The Haber process is the industrial manufacture of ammonia from nitrogen and hydrogen. Oxygen is not a reactant because ammonia contains nitrogen and hydrogen only. Chlorine would make chlorides, not ammonia, and ammonia is the product rather than a starting gas. This question checks the raw-material part of the Haber process rather than the temperature or pressure conditions.
Common mistake
Misunderstanding the Haber Process
Students often confuse the Haber process with other methods of ammonia production, thinking it involves only one raw material.
Remember that the Haber process specifically uses nitrogen and hydrogen as raw materials to produce ammonia.
