Consider the following generic chemical equation:
A+B - C + D
Reactant A contains 85.1 J of chemical energy.
Reactant B contains 87.9 J of chemical energy.
Product C contains 38.7 J of chemical energy. If
the reaction absorbs 104.3 J of chemical energy
as it proceeds, how much chemical energy must
product D contain? Explain your answer.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
