Consider the reaction: 2 HCl (aq) + Ba(OH)2 (aq) → BaCl2 (aq) + 2 H2O (l) ∆H = –118 kJ Calculate the heat when 200.0 mL of 0.500 M HCl is mixed with 300.0 mL of 0.200 M Ba(OH)2. Assuming that the reaction goes to completion, the temperature of both solutions was initially 25.0 oC, the final mixture has a mass of 500.0 g and a specific heat capacity of 4.18 J g –1 oC –1, calculate the final temperature of the mixture. Assume no heat is lost to the calorimeter and surroundings.
