Question

please give the chemical formula and valency of the following
✔️ferric hydroxide
✔️cupric
✔️ phosphide
✔️carbite
✔️borate
✔️nitrite

give the valency also

I will give you 15 points only for correct answer ​

Answer 1

1) Fe(OH)₃    VALENCY = 1

2) Cu₂O       VALENCY = 2

3) Phosphide itself is nothing, Phosphide ion is P³⁻   VALENCY = 3

4) It itself is nothing.....

5) BO₃³⁻ VALENCY = 3

6) NO₂⁻   VALENCY = 1

Answer 2

Answer:

The chemical formula and valency of the below given compounds are:

Explanation:

Ferric Hydroxide has the chemical formula Fe(OH)3 and its valency is 1.

Cupric oxide  has chemical formula Cu2O and its valency is 2.

Phosphide is an ion but not compound denoted by P3- and valency 3.

Carbide is also an ion C2- and valency 2.

Borate chemical formula is BO3. It has valency 3.

Nitrite has chemical formula NO2. it has valency 1.
