Question

Metal M reacts with oxygen to form metallic oxide MO. Desh oxide reacts with moisture and carbon dioxide of thermosphere to form a basic carbonate of metal M. The metal M is

Answer 1

ANSWER

$\huge\sf\pink{☞COPPER}$

EXPLANATION

• Metals form basic oxides on reacting with oxygen.Metal M reacts with oxygen to form MO which reacts with moisture and carbon dioxide of atmosphere to form carbonate is copper oxide.

• Copper metal on exposed to atmosphere reacts with oxygen, moisture and carbon dioxide to form a green coloured coating of copper carbonate and copper hydroxide.

• The reaction for the same is given as $\sf\green{Cu +H₂O +CO₂ +O₂ →}$$\sf\red{ Cu(OH)₂.CuCO₃}$
