1) Zn + CuSO4 > Cu + ZnSO4
Cu prefers to be an atom rather than an ion when compared to Zn and will be replaced by Zn
2) 2Na + 2H2O > 2NaOH + H2
If you look at H20 as H+ and OH-, then Na will want to be an ion more than H does, and will replace H
3) Cl2 + 2NaI > 2NaCl + I2
Cl prefers to be an ion more than I does and will thus replace I

the copper precipitates out of the solution and zinc sulfate forms... its a pretty simple single displacement reaction.

1. Zn(s) + CuSO4(aq) --> ZnSO4(aq) + Cu(s)
No steps to show.
2. 2Na(s) + 2H2O(l) --> 2NaOH(aq) + H2(g)
3. Cl2(g) + 2NaI(aq) --> 2NaCl(aq) + I2(s)
