Final answer:
The chemical formula for Carbon Monoxide is CO, consisting of one carbon atom and one oxygen atom bonded together.
Step-by-step explanation:
The chemical formula for Carbon Monoxide is CO. This compound is composed of one carbon atom (C) and one oxygen atom (O) joined by a triple covalent bond, with one of the bonds being a coordinate covalent bond. In this bond, one of the atoms contributes both of the electrons for the shared pair. Carbon monoxide is a toxic gas formed during the incomplete combustion of fossil fuels. When Carbon Monoxide (CO) reacts with additional oxygen (O2), it forms Carbon Dioxide (CO2), which is another gas produced by the combustion of fossil fuels and implicated in global climate change.
