hi there,:) I am just wondering, when balancing equations, because oxygen is a diatomic molecule, when it is in a compound, can it exist in threes of fives? for example, Fe2O3, or does it have to be 2Fe203. Or is it just when it is a single molecule of oxygen(and not in a compound) that it must be in atoms of two? So my question is, when oxygen in is a compound, does it have to exist in atoms of twos, or can it be uneven? sorry this may be a stupid question but its not clear in my textbook! ! thanksssss:D
