1. The problem statement, all variables and given/known data There is 100g of water inside of a 50g aluminum calorimeter. After a reaction takes place the temperature of the calorimeter goes from 20 degrees celsius to 25 degrees celsius Find the energy released by this exothermic reaction specific heat capacity of water is 4.18 and specific heat capacity of the aluminum calorimeter is 0.91 2. Relevant equations q=mcT 3. The attempt at a solution I approached this question using proportions since the total mass is 150, 1/3rd of the specific heat capacity is that of aluminum and 2/3 is that of water. q=150g(2(4.18)/3 + 0.91/3)(25-20) =2317.5J Is this approach correct?
