this passage describes a chemical reaction. read the passage. then, follow the instructions below. people have used silver (ag) throughout history to make jewelry and silverware. silver items are valued for their shiny appearance, but over time, they can become dull. the dullness comes from a layer of tarnish that gradually forms on the surface of silver items. tarnish, which is made of silver sulfide (ag2s), forms when silver combines with hydrogen sulfide (h2s) from the air. fortunately, you can remove tarnish by polishing silver. complete the table to classify the substances in this chemical reaction. substance reactant product hydrogen sulfide (h2s) silver (ag) silver sulfide (ag2s)
Answer
Answer:
| Substance | Reactant | Product |
|---|---|---|
| hydrogen sulfide ($H_2S$) | $\boxed{\surd}$ | |
| silver ($Ag$) | $\boxed{\surd}$ | |
| silver sulfide ($Ag_2S$) | $\boxed{\surd}$ |
Explanation:
Step1: Define reactants and products
Reactants are starting - materials, products are end - results.
Step2: Identify reactants
Silver ($Ag$) and hydrogen sulfide ($H_2S$) combine, so they are reactants.
Step3: Identify product
Silver sulfide ($Ag_2S$) is formed, so it is a product.
