Question

no balanced chemical equation a silver necklace reacts with sulfur in the air which make a black material called silver sulfide (tarnish). the equation is below. 2ag + s → ag₂s which chemical formula(s) represents the reactants? which chemical formula(s) represents the products? how many of each atom is present in the reactants? ag: s: how many of each atom is present in the products? ag: s: is this a balanced equation (yes or no)? explain why

Explanation:

1. Which chemical formula(s) represents the reactants?

In a chemical equation, the reactants are the substances that undergo the reaction and are written on the left - hand side of the arrow. The given chemical equation is \(2\text{Ag}+ \text{S}
ightarrow\text{Ag}_2\text{S}\). So, the formulas on the left of the arrow are the reactants.

In a chemical equation, the products are the substances formed as a result of the reaction and are written on the right - hand side of the arrow. In the equation \(2\text{Ag}+ \text{S}
ightarrow\text{Ag}_2\text{S}\), the formula on the right of the arrow is the product.

The coefficient of \(\text{Ag}\) in the reactant side is 2. So, the number of Ag atoms is equal to the coefficient.

Answer:

\(2\text{Ag}\) (Silver) and \(\text{S}\) (Sulfur)

2. Which chemical formula(s) represents the products?
