<span> Gas collisions are elastic. Gases mix faster than solids or liquids. Gases with larger molecular weights diffuse slower than gases with lower molecular weights. </span>

One from fe
And two from cl2
<span>Each mole contains Avagodro's number of atoms i.e. 6.023x10^23, so
3 moles x 6.023x10^23 atoms/mole = 18.069x10^23 atoms = 1.8x19^24 atoms </span>
How difficult it is to change an objects motion. Think of a tablecloth; it takes energy to move it from underneath objects on the table, and it takes energy to move the objects themselves on the table.
