Question

Hey mates ❤️❤️

!! provide me the symbols of the following compounds step by step .

1. Calcium Carbonate

2. Ferrous Oxide

3. Cupric Oxide

4. Sodium Bicarbonate ​

Answer 1

1.CaCO3

Calcium carbonate is a widely available natural inorganic compound, also known as limestone, chalk or marble. Formula and structure: The chemical formula of calcium carbonate is CaCO3and its molar mass is 100.1 g/m

2.FeO
3.Cu2O
Copper(I) oxide or cuprous oxide is the inorganic compound with the formula Cu2O. It is one of the principal oxides of copper, the other being CuO or cupric oxide. This red-coloured solid is a component of some antifouling paints. The compound can appear either yellow or red, depending on the size of the particles
4.NaHCO3

Sodium bicarbonate, also commonly known as baking soda, is commonly seen as a white, fine powder and has the chemical formula NaHCO3

Answer 2

${\huge {\mathfrak {Answer :-}}}$

✨ 1

Calcium is Ca and its valency is 2.

Carbonate is CO3 and valency is 2.

➡️ Hence, we get,

Calcium Carbonate = CaCO3.

✨ 2

Ferrous is Fe, with valency 2.

Oxide is 0, with valency 2.

➡️ So, we have

Ferrous Oxide = FeO.

✨ 3

Cupric is Cu, with Valency 2.

Oxide is O, with Valency 2.

➡️ Then,

Cupric Oxide = CuO.

✨ 4

Sodium is Na, having valency 1.

Bicarbonate is HCO3, with valency 1.

➡️ Thus,

Sodium Bicarbonate = NaHCO3.
