what should I include in my discussion when writing up my heating substances lab experiment?

We have no idea what you did; you want to put more information in your report than you did in your question.
how many moles h2o are used produced for each mole of h2 used?
You should post your own question instead of piggy backing onto another. Generally, piggy backed questions get overlooked. When you post your question, be sure to include all of the data; for example, what reacted with H2 to produce H2O?
