WebThis experiment essentially has three parts. In the first lab period, the data to determine the enthalpy of reaction for Mg + HCl and MgO + HCl will be collected (one trial on each). During the second lab period, data will be collected to calculate the Cp using the reaction of NaOH with HCl (two trials). Also, the enthalpy of reaction for the ...

Physical changes, such as melting or vaporization, and chemical reactions, in which one substance is converted to another, are accompanied by changes in enthalpy. Two other kinds of changes that are accompanied by changes in enthalpy are the dissolution of solids and the dilution of concentrated solutions.
