CEM 142 Exam 2 Questions With Correct
Answers
How |do |you |know |if |a |molecule |or |compound |will |conduct |electricity |in |solution? |- |CORRECT |
ANSWER✔✔-If |there |are |ions |present |in |solution |that |are |freely |moving |(ex: |NaCl)
Is |a |phase |change |a |chemical |reaction? |- |CORRECT |ANSWER✔✔-No. |Same |composition, |just |
breaking |IMFs.
Rearrangement |of |atoms |(atoms |conserved); |changes |in |location |of |valence |electrons; |bond |
breaking |and |forming |- |CORRECT |ANSWER✔✔-chemical |reaction
limited |application |(too |small); |ignores |role |of |water; |products |formed |will |always |be |water |
and |a |salt |- |CORRECT |ANSWER✔✔-Arrhenius |Acid-Base |Model
dissolves |in |water |to |give |H+ |(a |proton) |- |CORRECT |ANSWER✔✔-Arrhenius |acid
dissolves |in |water |to |give |-OH |(hydroxide) |- |CORRECT |ANSWER✔✔-Arrhenius |acid
shows |all |the |details |- |CORRECT |ANSWER✔✔-detailed |ionic |equation
species |that |don't |change |or |"watch |the |reaction" |- |CORRECT |ANSWER✔✔-spectator |ions
only |real |change |in |reaction; |does |no |include |spectator |ions |- |CORRECT |ANSWER✔✔-net |ionic |
equation
, more |general |and |useful |model; |attraction |of |partial |charges |on |two |molecules; |proton |
transferred |assisted |by |lone |pair |on |base; |good |for |when |protons |are |transferred |and |water |is |
the |solvent |- |CORRECT |ANSWER✔✔-Bronsted-Lowry |Model
proton |donor |- |CORRECT |ANSWER✔✔-Bronsted-Lowry |acid
proton |acceptor |- |CORRECT |ANSWER✔✔-Bronsted-Lowry |base
thought |of |as |an |electron |pair |donation; |encompasses |Bronsted-Lowry |and |Arrhenius |theories;
|base |considered |the |initiator |of |reaction; |use |arrow |using |method |- |CORRECT |ANSWER✔✔-
Lewis |Acid |and |Base |Model
electron |pair |acceptor; |have |place |to |accept |electrons |from |a |bond |breaking |- |CORRECT |
ANSWER✔✔-lewis |acid
electron |pair |donor; |have |available |pair |of |electrons |to |donate |into |a |bond |- |CORRECT |
ANSWER✔✔-lewis |base
acids |that |fully |ionize |in |solution |- |CORRECT |ANSWER✔✔-strong |acid
acids |that |partially |ionize |in |solution; |more |of |molecular |form |than |ionized |for |in |solution |- |
CORRECT |ANSWER✔✔-weak |acid
how |can |we |test |strength |of |an |acid |in |solution? |- |CORRECT |ANSWER✔✔-conductivity |test |
with |light |bulbs
tells |us |about |the |amount |of |acid, |NOT |the |strength |of |acid |- |CORRECT |ANSWER✔✔-Dilute |vs.
|Concentrated
