A seed crystal can be dropped into a saturated solution of sodium acetate. The solution will suddenly crystallize and turn to solid. Alternately, the solution may be slowly poured out onto a seed ...

A balloon filled with hydrogen gas also releases heat when lit on fire. Due to differences in energy density, the crystallization of sodium acetate releases more heat per mole than the hydrogen gas ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...

The higher the temperature, the faster the rate of a reaction will be. Sodium and chlorine react vigorously when heated, giving an orange flame and producing white sodium chloride.
