This (and the referenced website) is not correct. At room temperature, the scale height of air is about 8.5 km. The mass of the CO2 molecule is about 1.6 times larger, so the scale height is less – about 5.4 km. There will not be any significant difference in a 50 meter grain silo.

2021-04-07 · The Global Monitoring Laboratory conducts research on greenhouse gas and carbon cycle feedbacks, changes in clouds, aerosols, and surface radiation, and recovery of stratospheric ozone. The air density at sea level does not vary much around the world; the sea-level pressure varies by at most 5%, and the temperature rarely departs by more than 15% from 273 K, so that na remains within 25% of the value calculated here. The number density of CO2 is derived from the mixing ratio CCO2 = 365 ppmv: What is the difference between CO2 and Compressed Air (HPA) for paintball?

Even supercritical CO2 density is only 0.47 g/cc so we expect the mixture of those 2 would result in something in between (0.47 and 1 g/cc). I am looking for an explanation at the molecular level
At 80,000 ppm, CO2 can be life-threatening. CO2 is composed of one carbon atom & two oxygen atoms; Colorless; Odorless; Acrid Taste; Occurs naturally in the atmosphere at about 400 PPM; Formed by human and animal respiratory cycle as well as combustion; Non-flammable gas; Poisoning is rare; Hazard: Displaces oxygen in the room causing asphyxiation; Density: 44.01 kg/m3 (heavier than air) Se hela listan på differencebetween.com And CO2 serves to reradiate this energy back into outer space. This is proven born out by the fact that the energy density of solar radiation at the outer edge of the atmosphere is roughtly 1347 per meter square. And the aereal density at the earth's surface is much less than a quarter - the rest of the energy (simplification) is reradiated to The difference is that at high altitudes, the density of CO2 is too thin to recapture the infrared radiation (heat) that it emits. "In the upper atmosphere," explains Emmert, Because carbon dioxide (CO 2) is heavier than air (which is what you’re trying to prove – safely) it displaces oxygen and, therefore, presents a suffocation hazard.
