Answer:
A. Energy is necessary for bond formation.
C. Breaking bonds takes energy.
D. When bonds are formed, energy is released.
Energy is always required for bond formation because when a chemical reaction occurs, either molecular bonds are broken or other bonds are formed to make different molecules. Energy is released during bond formation and is an exothermic process because bond formation represents a stable configuration and the energy lost is released as heat energy that makes it more stable. Breaking bonds takes energy and is an endothermic reaction because energy is absorbed to break bonds.
Hope that helps. x

<u>Answer:</u>
<em>Adsorption is a phase conversion process that changes a mixture component from one state of matter to another is a </em><u><em>false statement.</em></u>
<em></em>
<u>Explanation:</u>
Adsorption is a process in which a solute accumulates on the surface of an adsorbent to form an atomic film.
The solute may be a gas or a liquid and the adsorbent will be a solid.
The resultant atomic film what we get is known as an adsorbate.
So molecules accumulate on the external or internal surface of the solids.
