Using the activity series predict whether each of the possible reactions listed below will occur. for the reactions that will occur, write the products and balanced equations 1. Ni(s) + CuCl2(aq) -->
2. Zn(s) + Pb(NO3)2(aq) -->
3. Cl2(g) + KI(aq) -->
4. Cu(s) + Fe(SO4(aq) -->
5. Ba(s) + H2O(l) -->

PLEASE answer ALL questions ASAP
