1.	The electronic configuration of metal A is 2,8,18,1. The metalA when exposed to air and moistureforms B a green layered compound. A with conc. H_2SO_4 forms C and D along with water . D is a gaseouscompound.Find A , B, C and D .
Answer» Solution :(i)The electronic configuration of metal (A) is 2, 8, 18, 1…. A is copper (Z=29) (ii) (A) Copper exposed to air and MOISTURE forms GREEN layered compound (B) that is copper CARBONATE. `underset"(A)"(2Cu)+O_2 +CO_2 + H_2O to CuCO_3 .underset"(B)"(Cu(OH)_2)` (iii) Copper (A) reacts with conc.`H_2SO_4`to give copper sulphate (C ) and Sulphur dioxide (D). `underset"(A)"(Cu)+conc.2H_2SO_4 to underset"(C )"(CuSO_4) + underset"(D)"(SO_2) + 2H_2O`
