Chem 162 Exam 2 with 100% Correct
Answers
Crystalline Solid - ANS-A solid that is made up of crystals in which particles are
arranged in a regular, repeating pattern
Amorphous solid - ANS-A solid made up of particles that are not arranged in a regular
pattern
Ionic - ANS-Made of ions; strong electrostatic attraction
Molecular - ANS-Made of molecules; weak IMFs
Network Atomic - ANS-Normal atoms and covalent bonds
Metallic - ANS-Metallic bonds
Parts of Crystal Structure - ANS-node<linear lattice<plane lattice<space lattice
Simple Cubic Cell - ANS-8(1/8)=1 atom
Body-centered Cubic - ANS-8(1/8)+1=2 atoms
Face-centered Cubic - ANS-8(1/8)+6(1/2)=4 atoms
Non volatile solute - ANS-Decreased Pvap of solution relative to pure solution
BP Elevation Formula - ANS-dTbp=iKbbsol.
Vant Hoff Factor (i) - ANS-Keep track of number of ions in solution
Osmosis - ANS-Net solvent flow across semi-permeable membrane from low
concentration to high solute concentration
Henry's Law - ANS-The partial pressure of a gas dissolved in a solution is directly
proportional to the partial pressure of that gas above the solution.
Osmotic Pressure - ANS-pi=iMRT
Isotonic - ANS-Same pi-soln
