Exothermic rxn:
Mg(s) + 2H(aq) --> Mg(aq) + H2(aq)
A magnesium sample having a mass of 0.0670 grams reacts with excess HCl and melts the ice in the calorimeter that resulted in a volume changed of 0.290 ml.
Calculate the number of grams of ice melted during this experiment.
Calculate the number of moles of ice melted during this experiment.
Calculate the heat released during this reaction.
Calculate the enthalpy of formation of magnesium, DHf(Mg2+), in Kcal/mole for this reaction.
