One of the hallmarks of science is that matter cannot be created or destroyed – it is just converted to another form. This is the basis of balancing chemical equations. Whatever is put into a reaction (the reactants) must be there in the same amount at the end of the reaction (the products), though they are likely in a different form.
This guide will help you with how to write and balance chemical equations.
