Chemical symbols are represented with their coefficients in a balanced reaction. Ethane and oxygen are the reactants, whereas carbon monoxide and water are the products.

4 HCl (g) + O₂ (g) → 2 Cl₂ (g) + 2 H₂O (l)

<h3>What is Carbon monoxide?</h3>

Carbon monoxide, a colorless, incredibly lethal, odorless, tasteless, and flammable gas with the chemical formula CO, is a little less dense than air. Carbon monoxide is a compound made composed of one carbon atom and one oxygen atom joined by three bonds. This is the simplest molecule in the oxocarbon family. The term "carbonyl" refers to the carbon monoxide ligand in coordination complexes. It is an essential part of many industrial chemistry procedures.

Carbon monoxide plays important biological roles in all phylogenetic kingdoms.
