Question 1

The heat of neutralization of HCl by NaOH is ΔH°rxn = –56.2 kJ/mol.  How much heat is released when 125 mL of 1.750 M HCl is mixed with 195 mL of  0.667 M NaOH?


Question 2

The heat of solution of calcium chloride CaCl2 is –82.8 kJ/mol, and the combined heats of hydration of 1.00 mole of gaseous calcium ions and 2.00 mole of gaseous chloride ions is –2327 kJ. What is the lattice energy of calcium chloride?
