Explanation: A thermochemical equation is a balanced chemical equation which require an enthalpy change.

A balanced equation is the equation in which number of atoms on reactant side is same as the number of atoms on product side.

A thermochemical equation for CaCl_2+H_2O is:

CaCl_2+2H_2O\rightarrow Ca(OH)_2+2HCl+heat

Here, heat is released in the reaction hence, it is a type of exothermic reaction.

A thermochemical equation for NH_4NO_3+H_2O is:

NH_4NO_3+heat\overset{water}{\rightarrow} NH_4^++NO_3^-

Here, heat is absorbed in the reaction hence,it is a type of endothermic reaction.

Describe in your own words, in terms of particle movement and energy, what occurs when a liquid is cooled to its freezing point.
IRINA_888 [86]
Liquids have free and fast moving particles. Liquids do not take a specific shape unless they are enclosed such as in a bottle. Anyway, since they are free flowing when they freeze, their movement becomes very slow. Eventually the particles will not have room to move as they used to and will be held in one place. The particles are still moving but they are only shaking or vibrating in the same place. You can't even tell this movement is happening, and that is what happens when liquid freezes.
