SOLVED:Magnesium sulfate is often used in first-aid hot packs, giving off heat when dissolved in water. When 2.00  g of MgSO4 dissolves in 15.0  mL of water (d=1.00  g / mL) at 25^∘ C in a coffee-cup calorimeter, 1.51  kJ of heat is evolved. (a) Write a balanced equation for the solution process. (b) Is the process exothermic? (c) What is qH2 O ? (d) What is the final temperature of the solution? (Specific heat of water is 4.18  J / g · ^∘ C.) (e) What are the initial and final temperatures in
