The chemical equation for the reaction of silver (Ag) and sulfur (S₈) to form silver sulfide (Ag₂S) is:

16Ag + S₈ → 8Ag₂S

Here's a breakdown:

* 16Ag: This represents 16 atoms of silver.

* S₈: This represents a molecule of sulfur containing 8 sulfur atoms.

* 8Ag₂S: This represents 8 molecules of silver sulfide, each containing 2 silver atoms and 1 sulfur atom.

Explanation:

* Silver and sulfur react directly when heated together.

* The reaction involves the transfer of electrons from silver atoms to sulfur atoms, forming ionic bonds.

* The resulting compound is silver sulfide, a black solid.
