Question

When cadmium sulfide is treated with sulfuric acid, fumes of hydrogen sulfide are given off. express your answers as chemical formulas separated by commas?

Answer 1

Answer: The chemical species are
`CdS,H_2SO_4,H_2S\text{ and }CdSO_4`

Step-by-step explanation:

When cadmium sulfide reacts with sulfuric acid, it leads to the production of hydrogen sulfide and cadmium sulfate.

The chemical equation for the reaction of cadmium sulfide and sulfuric acid follows:

`CdS+H_2SO_4\rightarrow H_2S+CdSO_4`

This is a double displacement reaction because here, exchange of ions are taking place.

Hence, the chemical species are
`CdS,H_2SO_4,H_2S\text{ and }CdSO_4`

Answer 2

The chemical formulas for their respective substances are the following:

Cadmium Sulfide: CdS
Sulfuric Acid: H₂SO₄
Hydrogen Sulfide: H₂S

This is a double replacement reaction where the substances of the reactants interchange to yield two products. The complete balance reaction would be:

CdS (s) + H₂SO₄ (aq) ----> CdSO₄ (aq) + H₂S (g)

The other product is Cadmium Sulfate.
