Question

A volume of solution is neutralized with xmol of HCl in a constant pressure calorimeter, which resulted in a rise in temperature. The heat capacity of the calorimeter system is y J/K. Some useful thermochemical equations are: _________

Answer 1

Calorimetry measures enthalpy changes during chemical processes using calorimeters. The temperature change in the calorimeter depends on the amount of heat released or absorbed and the heat capacity of the system.

Step-by-step explanation:

The thermal energy change accompanying a chemical reaction is responsible for the change in temperature that takes place in a calorimeter. If the reaction releases heat (9rxn < 0), then heat is absorbed by the calorimeter (qcalorimeter > 0) and its temperature increases.

The heat capacity of the calorimeter or of the reaction mixture may be used to calculate the amount of heat released or absorbed by the chemical reaction. The amount of heat released or absorbed per gram or mole of reactant can then be calculated from the mass of the reactants.

Calorimetry measures enthalpy changes during chemical processes, where the magnitude of the temperature change depends on the amount of heat released or absorbed and on the heat capacity of the system. Calorimetry is the set of techniques used to measure enthalpy changes during chemical processes. It uses devices called calorimeters, which measure the change in temperature when a chemical reaction is carried out. The magnitude of the temperature change depends on the amount of heat released or absorbed and on the heat capacity of the system.
