How to find speed of carbon dioxide?
At a certain tempature, the speed of oxygen molecules is 0.082 m/s. What is the speed of carbon dioxide at the same tempature?
I was gone for a few days and I need help catching up on chemistry.

Use Graham's law, which is derived from the fact that at the same temperature, the gases will have the same average kinetic energies.
Basically: (speed of A)/(speed of B) = [(mass of B)/(mass of A)]^(1/2)
So in this case, (speed of CO2)/(0.082 m/s) = (32.00/44.01)^(1/2)
and thus speed of CO2 = 0.070 m/s. A slower speed is expected since CO2 has more mass than O2, and therefore must have a lower velocity if they are to have the same average kinetic energy.
