Question

4. Write net ionic equations for reactions a), b) and d) only in Q. 1 above. 5. a) If the following reactions will take place, complete and balance it. If there is no reaction, state: a) AgNO3(ag) Cu(s) b) Cu(NOs)2 (aq) + Zn(s) c) Pb(NOs)2 (aq) + H2(g) d) AI(s) + HCI(aq) b) Balance the following half reactions in acidic solutions: i) VO2+ (aq) →V" (aq) 6. Balance the following reactions in basic solutions: a) Mno,(aq) + SO, (aq) MnO (aq)+ SO (a)+ H20().. in basic solutions: b) Mno42 (aq) MnO2(s) + O2(g)in basic solutions
