The chemical equation shown below represents a reaction that produces fuel for certain cars. CO + H2O - CO, + H2 Which substance represented in this equation is classified as an element? F CO GH, нсо, J H2 F b G C. H 1

The substance represented in the given chemical equation which is classified as an element is: J.

An element can be defined as a pure substance which comprises atoms with the same atomic number (number of protons) in its atomic nuclei.

Basically, an element is any pure substance that can't be broken down, decomposed or transformed into simpler substances by chemical or physical means.

In Chemistry, some examples of an element include the following:

From the above chemical equation, the substance which is classified as an element is hydrogen ().

The equation to this question is unclear. The equation is as follows:

CO + H2O ---> CO2 + H2

The substance classified as an element is H2.

Explanation:

An element is a substance composed of atoms of the same type. It is the simplest chemical substances that cannot be broken down by any chemical reaction. According to this question showing a chemical equation that produces fuel for certain cars:

CO + H2O ---> CO2 + H2

H2 is the substance that represents an element because it is made up of two atoms of hydrogen to form a molecule. Other substances in the reaction like (CO, CO2, H2O) are made up of two or more different atoms, hence, they are compounds not elements.
