Answer 1

1. Mg(S) + 2 HCl(aq) --------------- MgCl2(aq) + H2(g)

Mg(s) + 2 H+(aq) + 2 Cl-(aq) ---------------- Mg+2(aq) + 2 Cl-(aq) + H2(g)

Mg(s) + 2 H+(aq) --------- Mg+2 (aq) + H2(g).

2. 2Fe(s) + 6 HCl(aq) =------------ 2 FeCl3(aq) + 3H2(g)

   2 Fe(s) + 6 H+(aq) + 6 Cl-(aq) ----------- 2 Fe+3(aq) + 6 Cl-(aq) + 3 H2(g)

2Fe(s) + 6 H+(aq) ------------2 Fe+3(aq) + 3 H2(g)

4 .4 Fe(s) +3 SnCl4(aq) --------------4 FeCl3(aq) + 3Sn(s)

    4Fe(s) + 3 Sn+4(aq) + 12Cl-(aq) ------------ 4 Fe+3 (aq) + 12Cl-(aq) + 3 Sn(s)

4 Fe(s) = 3 Sn+4(aq) --------------- 4 Fe+3(aq) + 3 Sn(s)

5. Mg(s) + CuSO4(aq) ----------- MgSO4(aq) + Cu(s)

Mg(s) + Cu+2 (aq) + SO4-2(aq) ----------- Mg+2(aq) + SO4-2(aq) + Cu(s)

Mg(s) + Cu+2(aq) ----------- Mg+2(aq) + Cu(s).
