Give me 2 examples for both "endothermic change" and "exothermic change".20 pts. "as a donation"

An exothermic reaction releases energy into the environment. Some examples of these are:

The combustion of carbon to form carbon dioxide. Heat is released in the process.

Solidification of a liquid releases heat. This is one of the reasons why water does not get converted to ice spontaneously; the heat that is released has to be eliminated for the reaction to proceed. This is what happens in a refrigerator.

I found these answers. Hope this helps. c;

Exothermic reactions are chemical reactions that release energy. Example: Burning a candle is an example of an exothermic reaction because energy is being released during the reaction in the form of heat. Endothermic reactions are chemical reactions that absorb energy.
