@tracer: okay, I stand corrected. My chem professors in college said as much, so I really should have been more precise.
And like you, they also said that the difference in mass was so miniscule that it barely even existed, and in most chemical reactions the lost mass was all but impossible to measure. But nevertheless, a very, very, very, very tiny bit of mass WAS converted into energy every time a chemical reaction took place. From that standpoint, ultimately all reactions are fundamentally nuclear reactions.
But there again, we're talking about Shaftfly here. Since he doesn't seem to understand the difference between chemical and nuclear reactions and regularly rants, bitches and screams about the liberal anti-Christian bias of basic math, he's not going to be able to comprehend the difference anyway.
