Question

the chemical equation shown below represents a reaction that produces fuel for certain cars. co + h₂o------->co₂ + h₂ which substance in this equation is classified as an element? o₂ h₂ co₂ co

Explanation:

An element is a pure substance that cannot be broken down into simpler substances. \(H_2\) is made up of only hydrogen atoms. \(O_2\) is not in the reaction equation. \(CO_2\) is a compound (carbon and oxygen). \(CO\) is a compound (carbon and oxygen).

Answer:

\(H_2\)
