Most chemical reactions are exothermic, that is, they release a certain amount of heat as a by-product of the reaction. Endothermic reactions, those which absorb heat, also do occur, but they are more rare. Endothermic reactions are driven by entropy only, whereas exothermic reactions are driven by the energy that is released. The more energy is released, the more easily the reaction will occur.

What chemical reactions can give off heat or what?
These chemical reactions are named exothermic.
When chemical reactions occur energy is always absorbed?
No, chemical reactions can be endothermic or exothermic.
Why are exothermic reactions chemical reactions?
Exothermic reactions are chemical rections since these affects the composition and chemical properties of a matter and result in the formation of new substance. Example burning of coal , electrolysis of water.
Two types of chemical reactions?
Two kind of chemical reactions are exothermic and endothermic reactions. An exothermic reaction is one that releases energy. An endothermic reaction is one that absorbs energy. Hope this helps!! :)
Chemical reaction that releases energy?
All chemical reactions that release energy in the form of heat are called exothermic reactions.
Chemical reactions that release energy do if occur or don't?
These are called exothermic reactions.
What name is given to all chemical reactions which releases heat energy?
Exothermic reactions produce heat. Endothermic reactions take in heat from the surrounding area and get cold.
Chemical reactions that consume free energy are called?
Exergonic reactions.
What can an exothermic reaction do?
Exergonic reactions are chemical reactions in which energy is released as heat.
Are chemical reactions accompanied by chemical changes in energy?
Yes. Refer to endothermic and exothermic reactions to learn more.
How does the Alchemist might use both endothermic and exothermic reactions?
in chemical reactions bro.
How is endothermic reactions differ from exothermic reactions?
Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature. In contrast, exothermic reactions release heat into the surroundings, leading to an increase in temperature. Endothermic reactions have a positive enthalpy change, while exothermic reactions have a negative enthalpy change.
