during the process of extraction of pure copper from copper pyrite,SiO2 acts as acidic flux which combines with iron oxide(FeO) to form iron silicate(FeSiO3). CuFeS2 + heat ---> Cu2s + FeS + SO2 FeS + O2 ----> Feo FeO + SiO2 ----> FeSiO3
The electronic configuration of copper (29 cu) is: (1)1s 2 , 2s 2 , 2p 6 , 3s 2 , 3p 6 , 3d 9 , 4s 2 (2) 1s 2 , 2s 2 , 2p 6, 3s 2 , 3p 6 , 3d 10 , 4s 1 (3) 1s 2 , 2s
Isoelectronic species are: (1) K + Cl - (2) Na + Cl - (3) Na Ar (4) Na + Ar Ans: K + Cl -
