Question

oxygen + carbon \stackrel{\text{reactants}}{\longrightarrow} carbon dioxide \stackrel{\text{product}}{\longleftarrow}
is the reaction between oxygen and carbon reversible?
(1 point)
\bigcirc yes, because the reaction is indicated by two arrows.
\bigcirc no, because the product is not breaking down into reactants.
\bigcirc no, because there are more reactants than products.
\bigcirc yes, because the reaction is occurring in both directions.

Explanation:

In a reversible reaction, the products can break down to form the reactants. Here, the reaction is shown with a single arrow from reactants (oxygen and carbon) to product (carbon dioxide). This indicates that the reaction is going in only one direction (from reactants to product) and the product (carbon dioxide) is not breaking down into the reactants (oxygen and carbon).

Answer:

No, because the product is not breaking down into reactants.
