Of the following equations, identify which *two* are redox
reactions. (Hint: first check if it is easy to follow the charges
of species. If there are no full charges you will need to assign
oxidation numbers to atoms.)
Group of answer choices
CuSO4(aq) + Zn(s) ⟶
ZnSO4(aq) +
Cu(s)
C2H4 +
3O2 ⟶
2CO2 + 2H2O
AgNO3(aq) + NaCl(aq)
⟶ NaNO3(aq) + AgCl(s)
HBr + NH3
⟶ Br- +
NH4+
