To answer this question I would have to know the elements in the compound
13 atoms are in the chemical formula AI(PO4)3
hope that helps :-)
We write the following substances' chemical formula as follows:
Ferric hydrogen sulphate = Fe(HSO4)3.<span>
Tungsten (V) peroxide = </span>W2(O2)5<span>
Nitric acid = HNO3
Aluminum acetate = </span>C6H9AlO6
Hope this answers the question. Have a nice day.

Answer:
C
Explanation:
The oxidation number of Sulphur in SO4^2- is;
x + 4(-2) = -2
x - 8 = -2
x = -2 + 8
x = 6
Now,
the oxidation number of sulphur in H2SO3 is
2 (1) + x + 3(-2) = 0
2 + x -6 = 0
-4 + x = 0
x = 4
Hence, the oxidation number of sulphur changed from +6 to +4 which signifies gain of two electrons as shown in option C.
The answer would be option A which is the Earth’s Orbit
