1.	Give the necessary chemical equationsand balance them.(a) Reaction of red hot iorn with steam to giveFe_(3)O_(4) .(b)burning magnesiun ribbon in an atmosphere of nitrogen.(c ) Displacement of copper from the solution of its sulphate by zinc.
Answer» Solution :(a)`3Fe+underset("steam")(4H_(2)O)tounderset(("Ferroso FERRIC OXIDE"))(Fe_(3)O_(4)+4H_(2))` (b) `3Mg+N_(2) ""toMg_(3)N_(2)` ( c)`CuSO_(4)+Zn""to ZnSO_(4)+Cu`
