The initial amounts are given for the reactants, and a final
observed concentration for the product. If these amounts are
sufficient to permit equilibrium to be reached (you must determine
this) calculate Keq for the reaction at this temperature. (Hint:
notice the phase of each participant.) Assume V = 1.0 L
Balanced chemical equation: 6 H2 (g) + P4 (s) <-> 4 PH3
(g)
initial amounts: (6 H2) 3.86 x 10^(−3) / (P4)M 0.500 g/ (4PH3)
6.05 x 10^(−5)M

Determine the pH, pOH, and the concentration of all species at
equilibrium for each of the following solutions.
c) A solution containing 0.042 M ammonia (pKb = 4.74)
d) A solution containing 0.024 M ammonium chloride e) The pH of
a 0.125M solution of HCN is 2.87. Calculate Ka for HCN.
f)A weak monoprotic acid has a Ka of 1.6 X 10-5. Determine the
pH, pOH, and the concentration of all species at equilibrium if the
initial concentration of acid...

Determine the final temperature and pressure of a mixture of
CO2 (MW=44) and nitrogen if 3 kg of CO2 at
20°C and 1.5 MPa is mixed with 1 kg of nitrogen at 100°C and 0.75
MPa. Use cv of CO2 as 0.656 kJ/kg K and
cv of nitrogen as 0.752 kJ/kg K. The process can be
considered to be adiabatic.

What is the final concentration of a mixture of 1.50 liters of
1.50 M H2S04 and 500 mL of water ? Why does the moles of water not
effect the calculation? Why not use Mv (intial) =Mv(final) ?

1. Create a
relative frequency distribution table and
histogram to determine the percentage of students getting a
particular grade in statistics class. Do this by separating into 7
different classes by using 40’s, 50’s, 60’s, 70’s, 80’s, 90’s,
100’s. This will essentially be a table and graph of the
probability distribution for final grade.
2. Determine the
following
