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 .
Chemical 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
Chemical reactions that release heat (or light) energy are known as exothermic reactions.
No. They result in salts. By the way I dont mean cooking salt.
This depends upon the difference between the TOTAL ENERGIES that are contained within the chemical BONDS that existed before and exist after the chemical reaction.
No, exothermic reactions release heat while endothermic reactions absorb heat
ITS EXOTHERMIC
Exothermic reactions give out heat; Endothermic ones absorb heat.
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
Exothermic reactions
Exothermic reactions release energy. Endothermic reactions absorb energy.
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.
Exothermic reactions give out heat; Endothermic ones absorb heat.
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
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.
exothermic reactions are the reactions which give out heat and endothermic reactions are the reaction which absorb heat.so combustion is an exothermic reaction.
Exothermic reactions
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.
Exothermic reactions release energy. Endothermic reactions absorb energy.
Endothermic reactions absorb heat, while exothermic reactions emit heat. Both can be used to generate freezing depending on various chemical compounds.
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.
These chemical reactions are named exothermic.
No, endothermic reactions absorb heat. Exothermic gives off heat.
Exergonic reactions are chemical reactions in which energy is released as heat.
