When 10.0 g of potassium bromide dissolve in 50.0 g of water in a coffee-cup calorimeter, the temperature drops from 18.0°C to 9.5°C. Assume that all the heat is absorbed in the solution process comes from the water. (Specific heat of water = 4.18 J/g•°C.)
(a) Write a balanced equation for the solution process.
