175 g of water at 10.0ºC was placed in a coffe cup. 4.9 g of sulfuric acid at 10.0ºC was added. The temperature rose to 14.9ºC. The specific heat of the mixture to be 4.184 and all of the head produced is absorbed by the solution.How much heat was produced? Final answer in KJ 

(1J =1000KJ)

3.7 KJ
