Answer:

The given statement shows that the two families knew each other. Some people had left their home due to the war many years ago. Those who had stayed back thought that the ones who had left would never come back. That is why the woman feels surprised to see one of them come back. It also shows that selfishness of human behavior. People care for material things done for human beings. But it can't be said of all human beings. The narrator and her mother were totally different in their nature. They were trusting and loving human beings. Thus the given statement does give some clue about the story.

DIA [1.3K]

Answer:

Option B. 4 moles of the gaseous product

Explanation:

Data obtained from the question include:

Initial volume (V1) = V

Initial number of mole (n1) = 2 moles

Final volume (V2) = 2V

Final number of mole (n2) =..?

Applying the Avogadro's law equation, we can obtain the number of mole of the gaseous product as follow:

V1/n1 = V2/n2

V/2 = 2V/n2

Cross multiply

V x n2 = 2 x 2V

Divide both side by V

n2 = (2 x 2V)/V

n2 = 2 x 2

n2 = 4 moles

Therefore, 4 moles of the gaseous product were produced.
