During an experiment, jon exhales through a straw and blows bubbles into a solution. which observation would most likely indicate that a chemical reaction is occurring?
the bubbles disappear into the solution before reaching the surface. the gas forms a layer above the surface of the solution. the solution becomes very stirred up by the bubbles. the solution becomes cloudy with a white solid.

Answer is: The solution becomes cloudy with a white solid.

Balanced chemical reaction:

CO₂(g) + Ca(OH)₂(aq) → CaCO₃(s) + H₂O(l).

CaCO₃ is calcium carbonate, it is white cloudy solid with solubility in water.

Ca(OH)₂ is calcium hydroxide.

CO₂ is carbon (IV) oxide or carbon dioxide, gas that John exhales.

H₂O is water.

The correct answer is D.

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.
