Iron + Sulphuric Acid ____________________ e. Copper + Hydrochloric acid _____________________ f. Copper Sulphate + Zinc ___________________ g. Copper Sulphate + Iron ____________________ h. Copper + Zinc Sulphate ____________________ i. Copper + Iron Sulphate _____________________

Answer 1

a. )2[Mg]+O2--------> 2[ MgO]

b.)SO2+H2O----------> H2SO3 c.) Al+ 3[HCl] -----> AlCl3+ 3/2[H2], d. )Fe+H2SO4------> FeSO4+ H2 e. )Cu+HCl-----> (No reaction because in reduction potential series Cu is lower than H ). f.) CuSO4+ Zn-------> ZnSO4+Cu. g. )CuSO4+Fe---------> FeSO4+H2. h. ) Cu+ZnSO4-----> No reaction ( Cu present in lower position in reduction potential series than Zn and Fe also) . I) Cu+FeSO4 ----> no reaction
