The nitrate anion is Select one: a. a strong acid. b. a strong base. c. amphoteric. d. a strong reducing agent. e. a strong oxid
1 answer:
Answer: Option (e) is the correct answer.
Explanation:
Chemical formula of a nitrate ion is and it acts as a strong oxidizing agent because it itself gets reduced easily.
As we know that an oxidizing agent tends to oxidize other substances by itself gaining electrons. As a result, there will occur a decrease in its oxidation state.
The oxidation number of nitrogen in is +5. So, it gains electrons and helps in oxidizing other substances.
Thus, we can conclude that the nitrate anion is a strong oxidizing agent.

Se detailed explanation.
Explanation:
Hello,
In this case, since both magnesium and calcium ions are in group IIA, we can review the following similar properties:
- Since both calcium and magnesium are in group IIA they have two valence electrons, it means that the both of them have two electrons at their outer shells.
- They are highly soluble in water when forming ionic bonds with nonmetals such as those belonging to halogens and oxygen's family.
- Calcium has 18 electrons and magnesium 10 which are two less than the total protons (20 and 12 respectively) since the both of them have lost two electrons due their ionized form.
- Their electron configurations are:
It means that the both of them are at the region since it is the last subshell at which their electrons are.
Best regards.
