You'll need products, the correct ones, for these reactions, before you can balance them.  I'll give you one hint, no fewer than 3 different things happen for each of the two reactions you've quoted above. 

There's not much more in the way of hints that I can give you -- you either know what happens, or can look it up in your text or notes.  If you've just done an experiment in class, you should have been taught the relevant reactions, or been assigned to read about them.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
