5. A student mixes a 125.0 mL sample of a 1.00 mol/L strong common acid HCl(aq) with 2.06g of Mg,
in a coffee-cup calorimeter. Both reactants are initially at 23.0 °C. The temperature stabilizes after
the reaction at 35.1 °C.
a. Determine AHan for the neutralization reaction. Write a thermochemical equation for the
reaction. (8 marks)
b. List any assumptions that you made as you carried out your calculations. (1 mark)
