Question - A student, using an ice calorimeter, studies the enthalpy of reaction of the following exothermic chemical change: Mg(s) + 2H+(aq) ? ? Mg2+(aq) + H2(g) From data collected, it was determined that a magnesium sample having a mass of 0.0689 grams would react with excess HCl and melt the ice in the calorimenter that resulted in a volume change of 0.310 ml. Determine the following by referring to your laboratory procedures. Give special consideration to the section dealing with calculation. Calculate a value for the enthalpy change H during the reaction between HCl and Mg?

I just need a general explanation of it please- Thanks!
