Why do chemical equations need to be balanced…?
Ok, this is fairly simple, once you get the concept. The Law of Conservation of Energy states: “Matter cannot be created nor destroyed; it can only change from one form to another…” To give you an example: If you vaporize water, it is still water, but in gaseous form. You can’t see it, but it’s still the same quantity, and it’s still water. Your second point: “the mass of substances produced by a chemical reaction is equal to the mass of the reacting substances” If you take a basketball and photograph it, that will serve as your “product”. Then cut it up into 100 pieces. Those are your reactants. Although you have 100 pieces of basketball, it all still adds up to ONE basketball, in the end. Now, balancing equations is VERY important in chemistry. If you are trying to get water, you have to add the correct amount of moles of H2 and O2 to get H2O (sorry, I can’t do subscripts on this laptop). In terms of algebra: If 2+x=5, then you know that x has to equal 3. It all has to add up. In b
