The final temperature for the dissolution of 11.0g CaCl 2 in 125 g water at an initial temperature of 25.00 °C needs to be calculated given ΔH = -81.5 kJ/mol. Concept Introduction: Chemical reactions in general involve exchange of heat between the system (reactants and products) and the surroundings. The heat (q) absorbed or evolved is given as: q = m ×c×ΔT ------(1) Here, m and c are the mass and specific heat capacity of the substance ΔT = change in temperature= T f i n a l -T i n i t i a l
