Heat of Reaction

  1. Sep 24, 2005 #1
    I have trying to write a hypothesis for this reaction but boy am I lost

    NaOH --> Na(+) + OH(-)
    NaOH + H (+) + Cl (-) --> H20 + Na(+) + Cl(-)
    NaOH +OH (-) + H(+) Cl (-) --> H20 + Na(+) + Cl(-)

    Which reaction would produce the most heat and why??
    How would i calculate this

    Thanks

    Look up enthalpies of formations then compare- summation of the products minus the summation of the reactants. By the way, equation #3 makes no sense.
