Answer:
Manganese decreases from 4+ to 2+ (reduced and oxidizing agent) and nitrogen increases from 2+ to 5+ (oxidized and reducing agent).
Explanation:
Hello there!
In this case, according to the given redox reaction, we rewrite it as a convenient first step:
Next, we assign the oxidation numbers as follows:
Thus, we can see that both manganese and nitrogen undergo a change in their oxidation number, the former decreases from 4+ to 2+ (reduced and oxidizing agent) and the latter increases from 2+ to 5+ (oxidized and reducing agent).

An acidic solution would turn a blue litmus paper red due to the mobile and free hydrogen (H+) ions. These hydrogen ions affect the colour property of the litmus papers and thus the colour change. A litmus paper dropped into a solution of hydrogen ions turns red to indicate that the solution is acidic.
Answer:
D.) It is between groups 13 to 18 because it is a non-metal.
Explanation:
Here we can see the periodic table and what each element is.
It is a non - metal because it is gaseous.
Answer:
1 mole of Al³+
Explanation:
Balanced chemical equation;
Al³⁺ + Na₃PO₄ → 3Na⁺ + AlPO₄
From the above chemical equation, it is evident that this is displacement reaction which is a reaction involving one atom or charge displacing another one in the chemical reaction.
In this reaction, Al³⁺ has a charge of +3 while Na⁺ has a charge of +1. When Al³⁺ displaces Na⁺, it meets an anion of PO₄³⁻ and since both charges are equal, i.e +3 and -3, there's is a mutual exchange of electrons and bond formation occurs.
The ratio of AlPO₄ to Al³⁺ is 1 : 1
I.e 1 mole of Al³⁺ produce 1 mole of AlPO₄
