PART B
101 .
I II
The ideal gas law does not hold under low
temperatures and high pressure
BECAUSE interactions between particles cannot be
neglected under these conditions.
102 .
I II
An increase in entropy leads to a decrease of
randomness
BECAUSE the lower energy state of ordered crystals has a
high entropy.
103 .
I II
Two electrons in the 2s subshell
must have opposite spins
BECAUSE the Pauli exclusion principle states that no two electrons in the
same atom can have identical quantum numbers.
104 .
I II
Atom A with seven valence electrons forms AB 2 with atom B with
two valence electrons
BECAUSE B donates its electrons to fill the
outer shell of A.
105 .
I II
CO 2 is able to sublimate at atmospheric pressure BECAUSE its liquid form is impossible to produce.
