## How To Calculate Heat Absorbed Boiler And Coal By Solution

### Data & Results - Thermodynamics- Enthalpy/Hess's Law

Calculate the amount of heat evolved in each reaction, qrxn.If it is assumed that all the heat of reaction is absorbed by the solution and calorimeter, then: qrxn= -[heat absorbed by solution + heat absorbed by calorimeter] q rxn= -[(grams of solution * specific heat of solution * Delta Tsolution) + (Ccal * Delta Tsolution)] where Delta Tsolution= (Tmix - Tinitial) for each reaction mixture.
