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 .

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.
A chemical reaction that produces heat is what?
An exothermic reaction is a chemical reaction that produces heat as a byproduct. In these reactions, energy is released in the form of heat, increasing the temperature of the surroundings. This is in contrast to endothermic reactions, which absorb heat from the surroundings.
Why do some chemical reactions release heat while others absorb heat?
Chemical reactions release or absorb heat based on whether they release or require energy to break or form bonds between atoms. Reactions that release heat are exothermic, as they release energy, while reactions that absorb heat are endothermic, as they require energy input.
A chemical reaction that releases energy is called?
Exothermic reactions
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.
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.

Why do some chemical reactions release heat while others absorb heat?
Chemical reactions release or absorb heat based on whether they release or require energy to break or form bonds between atoms. Reactions that release heat are exothermic, as they release energy, while reactions that absorb heat are endothermic, as they require energy input.
Do chemical reactions transfer energy?
Yes, chemical reactions can transfer energy in the form of heat or light. Exothermic reactions release energy in the form of heat, while endothermic reactions absorb energy from their surroundings.
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.
Is reactants to products endothermic?
Not always. In a chemical reaction, the process can be either endothermic or exothermic. Endothermic reactions absorb heat from the surroundings, while exothermic reactions release heat into the surroundings. The specific reaction will determine whether it is endothermic or exothermic.
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.
What is the opposite of exothermic?
The opposite of exothermic is endothermic. Exothermic reactions are those which give off energy in the form of heat. Endothermic reactions require 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 chemical reactions can give off heat or what?
These chemical reactions are named exothermic.
Differentiate exothermic from endothermic reactions?
Exothermic reactions release heat energy to the surroundings, usually in the form of light or heat, resulting in a temperature increase. In contrast, endothermic reactions absorb heat energy from the surroundings, resulting in a decrease in temperature as the surroundings get colder.
