Question

How do you write, predict, and balance chemical reaction equations?

Answer 1

Break this down. Ask a more specific question. Your question is too broad and covers a lot of material that you need to study.

Answer 2

Ok, how do you know what the product will be based solely on the reactants?

Answer 3

it depends on what's reacting. Have you learned the 5 categories of chemical reactions? (e.g. single displacement, acid-base)
