The size of the molecule. Usually if a membrane is semi - permeable (only allows some molecules through by simple diffusion) the molecule that will be allowed through most is H2O(water).
Every time you talk to someone, the sound of your voice is going through H2O.
No, H2O is covalent.
Water?
h2o is an example of a polar molecule because when you look at the molecule it is not symmetrical. therefore it is polar.
H2o
H2o
liquid or water
no
is an example of h2o and oxy gen
Water (H2O) is an example.
Gas molecules move by diffusion, and water molecules move by osmosis. Edit: Osmosis refers only to water molecules (H2O) while diffusion refers to all over molecules.
