Question

How is copper extracted from its sulphide ore?explain various steps supported by chemical equations . Draw labelled diagram of the electrolyticrefining of copper

Answer 1

Copper was extracted by its sulphide pretty by the centrifugal process in which the a big tank contains pine oil and water mix it is done by compressed air.

Answer 2

Molecular mass of CO2= 12+(2*16)= 44u

1mole of CO2 =gram molecular mass of CO2=44g

Now,

44g of CO2=1mole of CO2

51.2g of CO2 =51.2/44= 1.16mole
