H2 will diffuse fastest as it has the least molecular weight.
co2 because it is lighter than oxygen gas
Well, for starters, I assume that you already know that dry ice, as it is commonly called, is frozen CO2. Second, I assume that the CO2 that you are referring to is in a gaseous state. If these assumptions are true, then mixing dry ice and CO2 would accomplish next to nothing. The gaseous CO2 would get colder, and the dry ice would sublime faster or slower, depending upon the surrounding temperature before adding the gaseous CO2 compared to the temperature of the gaseous CO2. If warmer, it would sublime faster. If colder, it will sublime slower.
There will be more and more carbon dioxide in the air. Carbon dioxide (CO2) is a powerful greenhouse gas. Plants (grass, trees and all vegetation) absorb CO2 out of the air and store it. If the CO2 build up is faster than the plants' consumption then there will be more CO2 in the atmosphere. The CO2 will hold more and more heat from the sun, and earth will get warmer and warmer.
CO2 is much smaller than SO2
H2 will diffuse fastest as it has the least molecular weight.
why does Co2 diffuse faster than So2
CO2 diffuses faster because it has a lower molecular mass.
oxygen

To make a co2 car go faster, make the body streamlined. Keep the weight down and make sure that the axles are smooth.
CO2 has lesser molecular mass than SO2 also Co2 is less reactive than SO2:)
no slower because it is lower pressure
Oxygen and co2
co2 because it is lighter than oxygen gas
Graphite
CO diffuses faster than CO2 because it is a smaller molecule
