When 90.0 g of a dilute aqueous acid solution was mixed with 90.0 g of a dilute base solution, the
temperature of the mixture increased from 24.4 \deg C to 30.3 \deg C. What is the heat of the reaction? Assume the
specific heat of the solution = 4.184 J \deg Cି ଵ gି ଵ and the heat capacity of the calorimetry =84 J \deg C-1 .
