Is thermochemistry hard
WitrynaThermochemistry deals with the changes in energy in chemical reactions. The difference between the enthalpy of one mole of a pure compound and the total enthalpy of the elements of which it is composed is called the heat of formation, , of the compound. WitrynaThermochemistry is the study of the energy and heat associated with chemical reactions and/or physical transformations. A reaction may release or absorb energy, and a phase change may do the same, such as in melting and boiling. definition. ...
