a reaction known to release 1.78 kilojoule of heat takes place in a calorimeter containing 0.100L of soln. the temperature rose by 3.65C. next, a small peice of caco3 was placed in same calorimeter and 0.100L of dilute Hcl was poured over it. the temperature of the calorimeter rose by 3.57 celsius.what is the heat in kilojoules released by the reaction?

First, please note that Hcl doesn't mean anything nor does caco3. You MUST learn not to take shortcuts or make typos.
Take a look at this site on the web and see if it describes exactly what the question asks.
