Well, I would balance

#### Explanation:

But you wanted whole number coefficients, so we double the creature to give..........

And for the oxidation of ammonia

Both equation are balanced with respect to mass and charge. Sometimes I find the half-integral coefficients useful in that it is easier to assess stoichiometry this way.

Are these redox reactions? Why or why not?
