it depend on endothermic and exothermic reactions . whenever bonds are breaked to form new products energy is absorbed e.g CaCO3 break down to CaO and CO2 if u heat it but on the other hand bond forming is the process in which heat is released e.g when Na and Cl combines energy is released and the product formed is NaCl .

∙ 15y agoChemical reactions can do both. Covalent bonds store energy. If the reaction is exothermic, energy (and heat) are released. If it is endothermic, energy is stored. Crazy Science Lady VT

∙ 11y agoChemical reactions that release heat (or light) energy are known as exothermic reactions.

∙ 13y agoThis depends upon the difference between the TOTAL ENERGIES that are contained within the chemical BONDS that existed before and exist after the chemical reaction.

∙ 10y agoNo, exothermic reactions release heat while endothermic reactions absorb heat

Differentiate exothermic from endothermic reactions?
Exothermic reactions give out heat; Endothermic ones absorb heat.
What do chemical changes always take in or give off?
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
A chemical reaction that releases energy is called?
Exothermic reactions
The expositon of dynamite is a chemical reactiondoes this reaction absorb or release energy?
Exothermic reactions release energy. Endothermic reactions absorb energy.
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.

What do chemical changes always take in or give off?
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
Which chemical reaction is responsible for producing heat?
All the exothermic reactions produces heat energy whereas all endothermic reactions absorb heat from the surrounding. For example burning of a coal is a exothermic process and melting of a ice is a endothermic process.
Is combustion exothermic or endothermic?
exothermic reactions are the reactions which give out heat and endothermic reactions are the reaction which absorb heat.so combustion is an exothermic reaction.
A chemical reaction that releases energy is called?
Exothermic reactions
Are exothermic reactions chemical?
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.
The expositon of dynamite is a chemical reactiondoes this reaction absorb or release energy?
Exothermic reactions release energy. Endothermic reactions absorb energy.
Does freezing lose heat or add heat?
Endothermic reactions absorb heat, while exothermic reactions emit heat. Both can be used to generate freezing depending on various chemical compounds.
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
What chemical reactions can give off heat or what?
These chemical reactions are named exothermic.
Do all acid reactions give off heat?
No, endothermic reactions absorb heat. Exothermic gives off heat.
What can an exothermic reaction do?
Exergonic reactions are chemical reactions in which energy is released as heat.
