Mrs. Zerlinsky wrote a chemical equation on the board and asked her class what should be changed to make it correct. She wrote:

water + glucose → carbon dioxide + oxygen + energy

What should be changed to show the correct chemical reaction?

Water should be traded with oxygen.
Glucose should be traded with oxygen.
Water should be traded with carbon dioxide.
Glucose should be traded with carbon dioxide.

Oxygen should be traded with water.

Explanation:

The proper equation is

glucose + oxygen  =>  carbon dioxide + water + 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.
