Question- When a 5.00g of strontium is added to 100.0g of water at 25.0 Celsius in a constant pressure calorimeter, the reaction below occurs and the temperature of the water increases to 8`.4 Celsius. Assuming that the specific heat of the solution is 4.18J/g*c, and assuming that no heat is lost to the surroundings, determine the value of delta H (in kJ/ mol Sr) for the reaction.
