The energy released by a chemical reaction can be measured using a calorimeter. When barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00g of water in the calorimeter decreases from 30.0⁰C to 8.0⁰C. If the specific heat of liquid water is 4.19J/g.⁰C, how much energy was absorbed by the reaction?​
