Answer:
A. Bubbles formed
Explanation:
When a student added a piece of limestone to a solution of hydrochloric acid, bubbles are formed.
The bubbles are as a result of the CO2 gas that is formed.
Below is the reaction:
CaCO3+2HCl → CO2+H2O + Ca++ + 2Cl-
From the left hand side, we can see that the reaction is with limestone and hydrochloric acid. Their reaction forms carbon dioxide gas (CO2), water (H2O), dissolved calcium (Ca++) and dissolved chlorine (Cl-) on the right hand side.
With due observation, bubbles will be seen evolving from the reaction. These bubbles formed is the carbon dioxide gas which reveals that a reaction is taking place.

These contradictory descriptions can be reconciled because they capture both sides of what Hester has become because of her experiences. She is seen as pure, warm, and tender, because she has turned her life around. She is pleased to have her daughter, she helps others in the community, and people have begun to see her as a better person.
She is also seen as cold, because she has to carry the burden of holding a secret (the identity of her husband), and cannot be with the man she wants to be with.
