Question

The green colour coating on copper when exposed to moisture is 

Copper Oxide + Copper Hydroxide

Copper Hydroxide + Copper Carbonate

Copper Hydroxide + Copper Nitrate

Copper Sulphate + Copper Oxide​

Answer 1

Answer:

Copper hydroxide+copper carbonate

Explanation:

Copper metal when exposed to air turns green in colour due to corrosion. When copper vessel is exposed to air in rainy season, the metal reacts with gases and moisture and atmospheric gases to form a mixture of copper carbonate and copper hydroxide. This gives a green colour to the surface of copper metal.
