AP Chemistry Final Exam Multiple
Choice Questions with Answers
Which of the following diatomic species has a bond order
of 2?
Li2
B2
N2
O2
F2 - Answer>> O2 (O2 has a double bond)
Which of the following has the largest bond dissociation
energy?
Li2
B2
N2
O2
F2 - Answer>> N2 (because N2 has a triple bond, making
it have the largest bond dissociation energy)

Answer>> trigonal planar
In which of the following process are covalent bonds
broken?
I2(s) → I2(g)
CO2(s) → CO2(g)
NaCl(s) → NaCl(l)
C(diamond) → C(g)
Fe(s) → Fe(l) - Answer>> C(diamond) → C(g)

solution. This decomposition is believed to occur
according to the reaction mechanism above. What is the
rate law? - Answer>> k[N2H2O2]/[H+]
Which is a precipitation reaction?
(A) H2SeO4(aq) + 2 Cl-(aq) + 2 H+(aq) → H2SeO3(aq) +
Cl2(g) + H2O(l)
(B) S8(s) + 8 O2(g) → 8 SO2(g)
(C) 3 Br2(aq) + 6 OH-(aq) → 5 Br-(aq) + BrO3-(aq) + 3
H2O(l)
(D) Ca2+(aq) + SO42-(aq) → CaSO4(s)
