It's usually because H2O is in excess, which means that we cancel it out, since there's no real change to it. I think Lavelle gave the analogy: If someone has one million dollars, and they give ten dollars to someone else, we don't say that they have $999,990. We just say that they have about a million dollars, since they have money "in excess". I hope that helps.
