Given the equation representing a reaction: H + H ---> H₂What occurs during this reaction? a. A bond is broken and energy is absorbed. b. A bond is broken and energy is released. c. A bond is formed and energy is absorbed. d. A bond is formed and energy is released.

The correct answer option d.

Explanation:

When chemical bonds are broken energy is supplied to bond to break it where as when bond is formed energy released during that process.

(ΔH = Positive)

The above reaction represents that two hydrogen atoms are combing together to form a single hydrogen gas molecule.During this process bond id forming between two atoms with release in energy.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
