CHEM 1465 Test 3 Questions with Complete
Solutions

face centered cubic unit cell coordination number 12




hexagonal closed paced unit cells coordination number 12




hexagonal close-packed every atom has 12 neighbors, but the shape of the pattern is

hexagonal and different from face centered




cubic close packed every atom has 12 neighbors, but the shape of the pattern is hexagonal

and same as face centered




bonding molecular orbital lower energy orbital




antibonding orbital higher energy orbital




n-type semiconductor more electrons; go into conduction band

, p-type semiconductor less electrons; create holes in valence band




p-n junction p-type and n-type connect




change in concentration use Kc formula to determine which reaction occurs; if more on

top, then forward. if more on bottom, then backwards




changing the partial pressue exactly like changing the concentration of a gas




changing the volume of the container if increase in pressure, move to side with less

moles. if decrease in pressure: move to side with more moles.




change in temperature: endo thermic heat added: EQ to right and Keq increases


polar covalent bonds unequal sharing of electrons




most electronegative element flourine
