2) Potassium nitrate
3) Ferric phosphate
4) Calcium oxide
5) Aluminum hydroxide

PLEASE WRITE EACH AND EVERY STEP....
PLEASE GIVE ACCURATE ANSWERS ......
I'LL DEFINITELY MARK AS BRAINLIEST....
OR ELSE I'LL REPORT IT....
PLEASE....
☺️☺️☺️☺️☺️​

Answer 1

Answer:

here is the answer of your question

explanation:

● Answers -

Chemical formula is deduced on the basis of cation & anion in the compound.

1) Sodium sulphate contains Na+ cation & (SO4)2- anion, thus molecular formula of sodium sulphate is Na2SO4.

2) Potassium nitrate contains K+ cation & (NO3)- anion, thus molecular formula of potassium nitrate is KNO3.

3) Ferric phosphate contains Fe2+ cation & (PO4)2- anion, thus molecular formula of ferrous phosphate is FePO4.

4) Calcium oxide contains Ca2+ cation & O2- anion, thus molecular formula of calcium oxide is CaO.

5) Aluminium hydroxide contains Al3+ cation & OH- anion, thus molecular formula of aluminum hydroxide is Al(OH)3.
