How do you know how to write the formula of a reaction?

Question Details:
How do you know how to write the formula of a reaction?
 
For example, how would I know that the Decomposition of N2H4 yields the products NH3 and N2, and not something else?

Is there some sort of organized way to find the Decomposition of a Compound?
I know there's an organized way to find the Combustion of a Compound, such as O2 will be one of the reactants and H2O will be one of the products.

I'm currently in General Chemistry, and I don't think I've learned a technique to write out the formula for the Decomposition of a Compound without knowing any of the products.

It would be great if someone could answer this question for me. Thanks.
Please ask for further assistance. AJ

AJ <3's comment:
"First off, N2H4 does decompose into the products NH3 and N2 [ Reaction's Formula: 3N2H4(l) --> 4NH3(g) + N2(g) ]. Second, the decomposition of N2H4 was just an example to help clarify in answering my question. Hope you understand."
Response Details:
First off, N2H4 does not decompose into the products NH3 and N2. Second, all you have to do is find the element in its natural state. So it would N2 + 4H. Nitrogen exists as a diatomic and H cannot. The application of decomposition is to find the change in enthalpy. :) Hope this helps.

"That wasn't not part of my question..."
Response Details:
Wow, that was rude...I still gave you the right answer when it comes to how to find the decom. Hope you understand.!!
