Concept explainers
Interpretation: The energy produced by reaction in calorimeter needs to be determined.
Concept introduction: The change in enthalpy at constant pressure is equal to the heat that flows as a form of energy.
Here, p indicates that the process occurred in the condition of constant pressure.
Answer to Problem 2RQ
The multiplication of mass, specific heat capacity and temperature change gives energy of the system.
Explanation of Solution
The formula used to calculate energy is,
Where Q is energy, s is specific heat capacity and
So, to calculate energy, mass of the sample (in gram) is to be multiplied by specific heat and temperature change.
Calorimeter is used to determine heat associated with a chemical system..
