Book Free DemoThe electronic configuration of metal A is 2,8,18,1.
The metal A when exposed to air and moisture, forms B, a green layered compound. A with con. \(H_2SO_4\) forms C and D along with water. D is a gaseous compound.
Find A, B, C and D.

Find A, B, C and D.
i. Metal (A) is .
ii. Action of Air and Moisture:
Copper gets coated with a green layer of basic (B) in the presence of \(CO_2\) and moisture.
\(2Cu\) + \(O2\) + \(CO_2\) + \(H_2O\) → .
iii. In the presence of air, copper dissolves in dilute \(H_2SO_4\) to form (C) and (D).
\(Cu\) + \(2H_2SO_4\) → + \(2H_2O\).
