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.

You must remember that oxidation number of hydrogen in acids is always +1, oxidation number of oxygen in oxides & acids is always -2... metals has always oxidation number on plus!
group NO3 comes from HNO3...and oxidation number of whole acid group is always on minus and equal to the amount of hydrogen atoms in this acid... so oxidation number of NO3 = -1
we have 2 NO3 groups so 2*(-1) = -2 and that is the reason why oxidation number of Fe in this formula must be +2... because sum of all elements always gives 0!
Now we could count of oxidation number for nitrogen... we write HNO3 and start counting from right to left:
3*(-2) from oxygens + 1 from hydrogen = -5
so nitrogen must have +5 oxidation number... because sum all in formula must be 0.
False. They don't borrow electrons at all. They already have their respective electron affinities. This is called as electronegativity, and it's an occurence where it already has its own from its actual structure. It never borrows any electrons at all.
