Which pair can form a gas in gas solution?
Answer and explanation
Correct answer: Oxygen and nitrogen
Oxygen and nitrogen are both gases and can form a uniform gaseous mixture like the gaseous components of air. Sugar and salt with water are solid-in-liquid solutions, while copper and zinc are solid metals that can form a solid alloy. Since only A has two gaseous components, it is the correct choice.
