is air heavier than carbon dioxide
carbon dioxide heavier than air
Carbon dioxide is a chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom and is heavier than air
I would like to point out that heavier than air reminds me of the joke about which is heavier, a pound of feathers or a pound of lead. When you say heavier you mean which is more dense, CO2 or air. CO2 is more dense and will sink to the bottom of a vessel.
