Starting with a stock solution of 18.0 M H2SO4, what is the
proper procedure to create a 1.00 L sample of a 3.0 M solution
of H2SO4 in a volumetric flask?
A. Add 167 mL of the stock solution to the flask, then fill the
flask the rest of the way with distilled water while swirling
the solution.
B. B. Add 600 mL of the stock solution to the flask, then fill the
flask the rest of the way with distilled water while swirling
the solution
C. Fill the flask partway with water, then add 167 mL of the
stock solution, swirling to mix it. Last, fill the flask the rest of
the way with distilled water.
D. Fill the flask partway with water, then add 600 mL of the
stock solution, swirling to mix it. Last, fill the flask the rest of
the way with distilled water.Correct
Answer: CExplanation:C Use M1V1 = M2V2 to determine the
necessary volume of stock solution.(18.0 M)V1 = (3.0 M)(1.0
L)V1 = 0.167 L = 167 mLWhen creating solutions with acid,
you always add some water first, as the process is extremely
exothermic and the water will absorb the generated heat.
$3B
$2B
A The temperature increase is indicative
of energy being released, meaning the
reaction is exothermic. The entropy
(disorder) of the system is increasing as it
moves from three gas molecules to five.
Answer is D
The overall reaction (excluding
spectator ions) is: 2 OH- + Cu2+ →
Cu(OH)2(s). Both the K+ and the
NO3- are spectator ions which are
present in solution both before and
after the reaction. Additionally, if
equimolar amounts of the two
reactants are initially present, the
OH- will run out before the Cu2+,
meaning that some Cu2+ ions will
also be present in the final solution.
Temperature in Kelvins is a
measure of kinetic energy.
When that temperature
doubles, so does the kinetic
energy. However, a doubling
of the temperature in
Celsius, while increasing the
amount of kinetic energy,
would not double it. ‫كان‬ ‫السؤال‬
‫فيه‬
° C
The farther away an electron is
from the nucleus, the less
ionization energy that is required to
eject it, and as a result, the
electron will have more kinetic
energy after it is ejected ‫يطرد‬
. The
3p subshell is the farthest one that
a neutral chlorine atom would have
electrons in. Beware of choice (D);
chlorine does not have a 3d
subshell.
10. N2(g) + O2(g) + Cl2(g) ↔ 2NOCl(g) ΔG° = 132.6 kJ/molFor the
equilibrium above, what would happen to the value of ΔG° if the
concentration of N2 were to increase and why?
A. It would increase as the reaction would become more
thermodynamically favored.
B. It would increase as the reaction would shift right and create more
products.
C. It would decrease because there are more reactants present.
D. It would stay the same because the value of Keq would not
change.Correct
Answer: DExplanation:D Adding (or removing) any species in an
equilibrium reaction does not change the equilibrium constant and also
does not change the magnitude of the Gibbs free energy at standard
conditions.
SF4(g) + H2O(1) → SO2(g) + 4HF(g) ΔH = -828 kJ/molWhich of the
following statements accurately describes the above reaction?
A. The entropy of the reactants exceeds that of the products.
B. H2O(l) will always be the limiting reagent.
C. This reaction is never thermodynamically favored.
D. The bond strength of the reactants exceeds that of the products.
Correct Answer: DExplanation:D One way to calculate enthalpy is by
subtracting the strength of the bonds broken in the reactants from the
strength of the bonds formed in the products. If the first value is greater
than the second value, the overall enthalpy change will be negative.

Isoelectronic. refers to two atoms , ions or molecules that
have the same electronic structure and same number of
valence electrons. The term means "equal electric" or "equal
