When chemical energy is released, it is released to the environment in the form of heat. This heat can be felt and measured. When a reaction results in an increase in temperature, energy has been released (it gets hot), and you have an exothermic reaction.
When chemical energy is absorbed, it is taken from the environment. This causes a decrease in the temperature of the surroundings. Energy has been absorbed from the environment around the reaction (it gets cold), and you have an endothermic reaction.

What is the difference between a exothermic chemical reaction and a endothermic chemical reaction?
energy released by the reaction or energy absorbed.
Is heat a form of energy released during a chemical reaction?
Yes, heat is often released or absorbed during a chemical reaction. This is because chemical reactions involve the breaking and formation of chemical bonds, and the energy difference between these bonds is released or absorbed in the form of heat.
What determines whether energy will be released or absorbed during a chemical reaction?
The difference in energy between the products and reactants of a chemical reaction determines if energy will be released or absorbed. If the products have lower energy than the reactants, energy will be released in the form of heat or light. If the products have higher energy, then energy will be absorbed.
What is the difference between enthalpy and heat of reaction in a chemical reaction?
Enthalpy is the total heat content of a system, including both heat absorbed and released during a reaction. Heat of reaction specifically refers to the heat released or absorbed when a specific chemical reaction occurs.
What is the difference between the heat of reaction and the heat of combustion?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction, while the heat of combustion specifically refers to the heat released during the combustion of a substance with oxygen.
What is energy that is stored in bonds between atoms in a compound?
Chemical energy is the energy stored in bonds between atoms in a compound. This energy is released or absorbed during chemical reactions.
Which term describes energy stored in the bonds between atoms?
The energy stored in the chemical bonds between atoms is potential chemical energy.
How can one determine the change in enthalpy (H) for a chemical reaction?
One can determine the change in enthalpy (H) for a chemical reaction by measuring the heat released or absorbed during the reaction using a calorimeter. The difference in heat between the products and reactants gives the enthalpy change.
What is the difference between endothemic and exothemic?
The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.
Look at the chemical reaction How does the chemical energy of the reactants compare to the chemical energy of the products?
In a chemical reaction, the chemical energy of the reactants is typically higher than that of the products. This is because energy is needed to break the bonds in the reactants to form new bonds in the products. The difference between the energy of the reactants and the products is often released or absorbed as heat.
When energy is absorbed or released is it chemical or physical change?
When energy is absorbed or released, it can be associated with both chemical and physical changes. Chemical changes typically involve the breaking or forming of bonds between atoms, resulting in energy changes, while physical changes involve altering the state or arrangement of molecules without affecting their chemical composition, which can also result in energy absorption or release.
Where is chemical potential energy stored?
Chemical potential energy is stored in chemical bonds between atoms and molecules. When these bonds are broken or formed during a chemical reaction, energy is released or absorbed.
