What does it mean for an equation to be balanced and why must you keep an equation in balance?

You need the same atoms coming out as went in. There are no nuclear reactions in a chemical reaction :)
NOT H2 + O2 --> H2O, NO way
2 hydrogen atoms went in, 2 came out
BUT
2 oxygen atoms went in, but ONLY ONE came out
so we need
2 H2 + O2 --> 2 H2O
4 H atoms left, 4 H atoms right
2 O atoms left, 2 O atoms right

Same thing, it has to be and remain the same on both sides
If you add 5 on the left, you must add 5 on the right
If you multiply left by two, you must multiply right by two
If you add 5 on the left, you must add 5 on the right
If you multiply left by two, you must multiply right by two

ashlyn, not until you get linear relations right, sorry. By the way I graduated MIT in 1959.
