State the temoerature rose small piece of calcium carbonate

Reference no: EM13207385

A reaction known to release 1.78kJ of heat takes place in a calorimeter containing .100L of solution. The temoerature rose by 3.65C. Next, a small piece of calcium carbonate was placed in the same calorimeter and .100L of dilute HCl was poured over it. The temperature of the calorimeter rose by 3.57C. What is the heat, q, in kJ released by the reaction?
