Question

Determine which elements or compounds are missing from the following reaction equation: silver + sulfur → A Question Progress A. lead bromide B. silver sulfide C. sulfuric acid D. glucose

Answer 1

In the given reaction equation, silver + sulfur, the missing compound that is formed is silver sulfide.

Silver (Ag) is a metal, and sulfur (S) is a non-metal. When these two elements react, they combine to form a compound called silver sulfide (Ag2S).

It's important to note that the subscript 2 in Ag2S indicates that there are two silver atoms bonded to one sulfur atom. This balanced formula accurately represents the compound formed in the reaction.

Therefore, the missing compound from the equation is B. silver sulfide.

Answer 2

Answer: B. silver sulfide

Step-by-step explanation:

The law of conservation of mass states that atoms cannot be created nor destroyed in a chemical reaction, so an element that is NOT on the reactants side (the left side) CANNOT be on the products side (the right side), because that element cannot be created in a chemical reaction.

Our reactants are silver and sulfur, so only silver and sulfur will be in the products, so that eliminates lead bromide and glucose, because they do not have silver nor sulfur in them. Sulfuric acid has sulfur in it, but it also has oxygen and hydrogen, but no silver, so that choice is eliminated as well. That leaves silver sulfide, which is Ag₂S.

I hope this helps! :)
