Answer 2

Formulas of Compounds by Valency:

Here are the formulas of the compounds mentioned, categorized by their valency:

1. Valency III: - Sg(III)O: Sg2O3 - MgN(III): Mg3N2 - HS(II): H2S

2. Valency IV: - Mn(IV)O: MnO2

3. Valency V: - Mn(V)O: Mn2O5 - N(V)O: N2O5 - P(V)O: P2O5 - As(V)O: As2O5

4. Valency VI: - Si(IV)H: SiH4

Please note that the valency of an element refers to its ability to form chemical bonds. The valency of an element determines the number of electrons it can gain, lose, or share in order to achieve a stable electron configuration. The valency of an element can vary depending on the specific compound it forms.
