In an exothermic reaction where does the energy released as heat come from ?

Many chemical reactions give out energy in the form of heat, light or sound. Some reactions give out their energy over a long time. The energy comes from the bonds that hold the atoms together in the molecules

Explanation:

exothermicOf a chemical reaction that releases energy in the form of heat.

the answer is

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
