What about one? If I do one for you I think you should be able to do the others.
Cl2 + 2NaBr ==> 2NaCl + Br2
oxidation half:
2Br^- ==> Br2 + 2e or
2NaBr ==> Br2 + 2Na^+ + 2e
reduction half:
Cl2 + 2e ==> 2Cl^-
Other redox equations (None are balanced):
Cu + HNO3 ==> Cu(NO3)2 + NO2 + H2O
Na + H2O ==> NaOH + H2
Al + AgNO3 ==> Ag + Al(NO3)2
S + O2 ==> SO3
If you will post your answers someone here will check them for you.
