Magnesium Reacting With Acids, molar enthalpy

  1. Mar 29, 2015 #1
    • You have to show your attempts at answering the question, this is a forum policy.
    Mg(s) + 2HCl (aq) --> H2(g) + MgCl2(aq) + heat


    Mg (s) + H2SO4(aq) --> H2 (g) + MgSO4 (aq) + heat


    Mg(s) + 2C2H4O2(aq) --> H2 (g) + Mg(C2H3O2)2 (aq) + heat

    Which reaction will produce the great molar enthalpy and which the least? Why?

    What do you think determines the molar enthalpy?
