questions with answers
Electric Dipole Moment - ** VERIFIED ANSWERS **✔✔Neutral molecule with uneven charge
distributions (partial charges) e.g. H2O
Diffusion - ** VERIFIED ANSWERS **✔✔Movement of molecules from areas of high to low
concentrations e.g. Volatile Perfume distributing through the air
Osmosis - ** VERIFIED ANSWERS **✔✔Diffusion of WATER through a membrane e.g. Aquaporins
(biological proteins)
Hydrophilicity - ** VERIFIED ANSWERS **✔✔"Water Loving" e.g. Charged ions that interact with
the Electric Dipole Moment in water. (Soluble)
Hydrophobicity - ** VERIFIED ANSWERS **✔✔"Water Fearing" e.g. molecules with equal
distribution of charge such as Triglycerides (Insoluble)
