You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.
The difference between endothermic and exothermic energy is that exothermic energy is the reaction that releases energy and endothermic is the reaction in ehich energy is absorbed.
An endothermic reaction absorbs heat. It cannot proceed without the addition of heat. An exothermic reaction releases heat. Since heat causes chemical reactions to go faster, an exothermic reaction can "feed on itself" and get out of control, releasing damaging amounts of heat and, if proceeding in a closed container, causing an explosion.
energy released by the reaction or energy absorbed.
Exothermic reaction is just one of the two possible chemical reactions: either exothermic or endothermic. (No difference but heat release)
This is a strong exothermic reaction.
Exothermic
EXTREMELY!!!!! exothermic. As in fires and explosions exothermic.
Nothing to explain; that is the way EXO- and ENDOthemic reactions are called by definition
Endothermic
An endothermic reaction absorbs energy, making its environment cooler. Ab exothermic reaction releases energy, making its environment warmer.
endothermic because it absorbs energy, and not releasing it
The reaction between calcium and water is very exothermic.
