Magnesium sulfate is often used in first-aid hot packs, giving off heat when dissolved in water. A coffee-cup calorimeter at 25 contains 15.0 mL of water at 25 . A 2.00-g sample of is dissolved in the water and 1.51 kJ of heat are evolved. (You can make the following assumptions about the solution: volume = 15.0 mL, density = 1.00 g/ml, specific heat = 4.18 )
a.) What is the balanced equation for the solution process?
b.) Is the process exothermic?
c.) What is
d.) What is the final temperature of the solution?
e.) What are the initial and final temperatures in ?
