* Diffusion is the spontaneous movement of particles from an area of higher concentration to an area of lower concentration. This movement is driven by the random motion of molecules.
* Gases have a high degree of molecular motion, making diffusion a very efficient process.
* CO₂ and Bromine are both gases at room temperature.
* Even though bromine gas has a much higher molecular mass than CO₂, it will still diffuse. This is because diffusion is primarily driven by the concentration gradient and the random motion of molecules.
Therefore, if you were to place a container with CO₂ gas and another container with bromine gas next to each other, the gases would eventually mix through diffusion.
Important Note: Bromine gas is very toxic and dangerous. You should never handle it without proper safety equipment and precautions.
