Homework Help: Energy Produced by Reaction

  1. Jan 10, 2006 #1
    the reaction of H and F produces about 500 kj/mol of energy:

    how much energy is produced by the reaction of 2.0kg of H with 38 kg of F to produce 2 kmol of HF?

    The answer is 5.0x 10 to the exponent 5 kJ... but i'm not sure why...

    Please help! Thanks!

    This is chemistry and should be in the chemistry forums, but try calculating the number of moles of each reactant. Remember Hydrogen and Florine are diatomic.
