Explanation:
I had this same question on one of are worksheets is D I can’t really explain it but the answer is D
Option A is the only answer here.
The artificial fixation of nitrogen (N2) has enormous energy, environmental, and societal impact, the most important of which is the synthesis of ammonia (NH3) for fertilizers that help support nearly half of the world's population.
<h3>
Artificial fixation of nitrogen</h3>
We can generate ammonia gas in the research centre by slowly heating ammonium chloride (NH4Cl) and slaked lime [Ca(OH)2].
The following reaction can be used to make H₂ for the synthesis of ammonia from the greenhouse gases carbon dioxide and methane: CH₄(g) + CO₂(g) ⇄ 2CO)g) + 2H₂(g
When added to a solution of copper sulfate, ammonia turns the solution deep blue.
NH3 + CuSO4 + nH2O→ [Cu(NH3)4(H2O)n]SO4
