Achemical reaction has not occurred if the products have

A chemical reaction has not occurred if the products have not been formed.

Explanation:

Chemical reactions involves the process by which reactants undergo chemical change, and they yield one or more products, which usually have properties different from the reactants.

the energy to form plasma comes from heat or electricity in the atmosphere!

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.

hope this .
