Non polar molecule example
oils, fats, lipids
Hydrophilic
water loving
polar molecule that dissolves in H2O
How does hydrogen bonding affect life?
when water is solid, it allows H2O to form hydrogen bonds and spread out
solids are less dense
solvent
what is doing the dissolving
A hydrogen bond is formed when
partially negative charged oxygen atoms and the partially positive charged hydrogen atom of a molecule bonds to O, N, F of another molecule
Hydrophobic
water fearing
non polar molecule that do not dissolve in H2O
Active site
specific location where the substance bonds on enzyme
Ion
atom that has lost or gained one or more electrons becomes and ion and carries an electric charge
Compound
pure substance formed when different elements combine
density
compactness of a substance
ratio of mass to volume
d=m/v
Meniscus
cup shaped form at the top of H2O
Capillary action
tendency of a liquid substance to move along a solid substance due to adhesion. cohesion also allows H2O to pull H2O along with it
surface tension
molecules of a liquid stick together
hydrogen bonds cause this with H2O
H2O strider stands of surface of H2O
non polar molecule
molecule without an electical charge
do not dissolve in H2O
ex- lipids
polar molecule
unequal distribution of charges on the water molecule make it a polar molecule
H2O molecule has a positive and negative end
