Question

write stepwise formula for the given compound
1. calcium carbonite 2.ammonium Sulphate​

Answer 1

Answer:

Calcium carbonate is a chemical compound with the formula CaCO3

The formula mass for sodium sulfate was calculated on page T-9. Referring to those numbers, the formula Na2SO4 means: two moles sodium (45.98 g), one mole sulfur (32.06 g), and four moles oxygen (64.00 g) combine to form one mole of sodium sulfate (142.04 g).

Answer 2

1. The chemical formula of calcium carbonate is CaCO3. The molecule is formed by the calcium cation Ca+2 and the carbonate anion CO3−2.

2. The chemical formula of ammonium sulfate is (NH4)2SO4. Each molecule of ammonium sulphate contains two NH4 + ions and one SO4 2- ions.
