how many of each atom is present in the

Explanation:

For "Which chemical formula(s) represents the reactants?"

In a chemical equation, reactants are the substances that undergo a chemical reaction and are written on the left - hand side of the arrow. In the equation \(2Ag + S
ightarrow Ag_2S\), the substances on the left side of the arrow are silver (represented by \(Ag\)) and sulfur (represented by \(S\)).

In a chemical equation, products are the substances that are formed as a result of the chemical reaction and are written on the right - hand side of the arrow. In the equation \(2Ag+S
ightarrow Ag_2S\), the substance on the right side of the arrow is silver sulfide, represented by \(Ag_2S\).

Step 1: Analyze the number of Ag atoms

In the reactant side, the formula for silver is \(2Ag\). The coefficient 2 in front of \(Ag\) indicates the number of silver atoms. So, the number of silver (\(Ag\)) atoms is 2.

Step 2: Analyze the number of S atoms

In the reactant side, the formula for sulfur is \(S\) (with an implicit coefficient of 1). So, the number of sulfur (\(S\)) atoms is 1.

Answer:

\(Ag\) (silver) and \(S\) (sulfur)
