Diffusion is a type of passive transport but the answer I think you are looking for is this: water, gasses(N,O2,CO2...), and ions(K+, Na+...)
Liquids diffuse at a slower rate than do gases because they have much less kinetic energy.
Hydrogen and Helium
The two unreactive gases in the air are nitrogen (about 78%) and oxygen (about 21%).
Oxygen and carbon dioxide are the two important gases that diffuse across the respiratory membrane. Oxygen moves from the alveoli into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
snails use there thin layer of skin to diffuse any organic gasses.
No, they diffuse until an equilibrium is established meaning there is an equal spread of the gasses molecules. - Tony
Many gasses, water and lipids to name a few.
Carbon and Oxygen. The gas is carbon-monoxide.

Oygen and Hydrogen
No. Earth is composed of slolid minerals. Earth's atmosphere is mostly made up of two gasses: nitrogen and oxygen.
Methane and carbondioxide.
