### 8.53

In example 8.53, why do we use q=C(change in T) rather than q=mC(change in T)?

The solution involves using the heat capacity of the calorimeter, so we would use $q = C_{cal} \Delta T$, which doesn't require the mass of the calorimeter.

For this problem, why do we need to take into account that q reaction is equal to -q calorimeter as it states in the solutions manual?
