Chemistry Flashcards
no crystal lattice
liquid water
crystal lattice forms
in ice
which is more dense, water or ice
water is more dense
polar molecules and ions dissolve readily in water
hydrophilic
non polar molecules do not dissolve in water
hydrophobic
water loving
hydrophilic
water fearing
hydrophobic
what is hydrophobic interaction
water forces nonpolar molecules together
why do hydrophobic ineractions occur
minimizes the disruptive effects of non polar molecules on the hydrogen bonded water network
name the chemical bonds (strong to weak)
covalent, h-bonding, ionic, hydrophobic, van der waals
what is a mole
the amount of a substance in grams whose weight is equal to its molecular weight
what is 1 molar solution
one mole of a compound dissolved in water to make one liter
release/donate h+ ions
acids
accept h+ ions
base
what is a buffer
makes the overall solution resistant to pH change
what do buffers react with
both acids and bases
pH is defined as
the negative logarithm of h+ concentration in moles/liter
name the macromolecules
lipids, sugars/carbohydrates, proteins, nucleic acids
reaction to remove a monomer from a polymer
condensation reaction
water is released
reaction to add a monomer from a polymer
hydrolysis
water is added
