Question 1 Given the reaction below and its standard enthalpy change, if 0.639 moles of CaCl2 is dissolved into water that is initially at 15.0 °C, and this creates 464 mL of solution, what will the new temperature of the solution be? You may assume the resulting solution has the same density and specific heat as pure water. Answer in degrees Celsius. CaCl2(s) <---> Ca²† (aq) + 2 Cl¯ (aq) AHO = -72.0 kJ/mol -140 22
