Proton donor
Properties of water
cohesive and adhesive liquid at room temp temp change is slow high heat of vaporization frozen is dense
compund
2 or more diff atoms combined
buffers
used to inhibit drastice change in pH
A chemical that resists changes in ph when either an acid or a base is added to a solution containing the buffer in
pH scale

neautral
diatomic
N2, O2, Br2, F2, Cl2, I2, H2
hydrophilic
likes water
ionic bond
transfer electrons
hydrophobic
afraid of water
log rhythmic
each time you change direction it is 10 times greater
protons
positive charge
weight
determined by gravity
exchange rxn
Combo of synthesis and decomposition
isotopes
element with a different number of neutrons
hydrogen bonds
an attraction between the positive and negative poles of charged atoms
