Magnesium sulfate is often used in first-aid hot packs, giving off heat when dissolved in water. A coffee-cup calorimeter at 25ºC contains 13.2 mL of water at 25ºC. A 1.50-g sample of  MgSo4 is dissolved in the water and 1.13 kJ of heat is evolved. (You can make the following assumptions about the solution: volume = 13.2 mL, density = 1.00 g/mL, specific heat = 4.18 J/g · ºC.) Write a balanced equation for the
