Which option can generally form a homogeneous gaseous solution?
Answer and explanation
Correct answer: Nitrogen and oxygen
Nitrogen and oxygen are both gases and mix uniformly to form a gaseous solution, as seen in the gaseous mixture called air. Sugar in water and salt in water form liquid solutions because water is the solvent. Copper and zinc can form brass, a solid alloy or solid solution. Therefore, option A correctly identifies the gaseous example.
