Tallow (2)
(1) hard, fatty substance made from rendered animal fat
(2) used in making soap and candles
protonation
The addition of a proton to a particle, forming a conjugate acid
thiosulfate ion
S2O3, 2 minus
Steric # 5
trigonal bipyramidal
isotopic notation (2)
(1) inverted mass # and atomic #, followed by element symbol, followed by (possible) ionic charge as a superscript
(2) aka nuclear notation
atomic mass (2)
(1) mass in u
(2) nearly the same as mass number, except for mass defect
tetrahedron (2)
(1) a solid figure having four equal, triangular faces (2) a triangle based pyramid
frequency, physics (2)
(1) the number of waves that pass a fixed point, per unit time; (2) measured in Hz (hertz)
boiling point of water
212 degrees Fahrenheit, 100 degrees Celsius
molecular dissolving in water (3)
(1) dissolves well if there are dipole-dipole forces (2) even better if there are hydrogen bonds (3) unlike ionic compounds, molecules do not dissociate in solution
distillation
the process of separating the components of a liquid mixture through selective evaporation and condensation
electrostatic
relating to stationary electric charges or fields, rather than electric currents
amorphous
having no definite shape or form
charge vs mass (4)
(1) two fundamental properties of objects and particles (2) the former is how strongly it responds to an electrical force (3) the latter is how strongly it responds to a gravitational force (4) ie how strongly such forces will “pull on it”
dipole
a molecule in which a region of positive charge is separated from a region of negative charge
