∙all made of carbon, hydrogen, and oxygen
∙one form of energy storage
,colligative properties: physical property of a substance that depends only on
the concentration of solute

1. vapor pressure
-how quickly a liquid will evaporate
-adding solute decreases vapor pressure
2. boiling point
-with a lower vapor pressure, it is harder for a liquid to vaporize
-adding solute increases boiling point
3. freezing point
-solute particles prevent liquid particles to organize themselves to
condense into a solid
-adding solute decreases the freezing point

conversion of a substance into different substance (ex: rusting iron)
conversion factor
Give this one a try later!
a ratio of equivalent measurements used to convert a quantity from
one unit to another
,non electrolyte

∙not conductive
∙when dissolved, it does not ionize at all

∙polymers of nucleotides
∙linked by phosphodiester bonds between sugars in
adjacent nucleotides
∙one end of the nucleotide has a free phosphate group,
and the other end has a sugar with a free hydroxyl
group
