Combinations of palladium(II) cations, triphenylphosphine molecules, chloride anions, and ammonium cations result in the formation of a series of five coordination compounds.
a) Write the modern formulas for the members of this series.
b) Which compound or compounds would have the greatest conductivity in solution? Briefly explain your answer.
c) Write the formula for the neutral member of this series as Werner would have written it. Assuming that palladium(II) has a square planar coordination sphere, how many isomers would this compound have?
A buffer solution of a weak base and its salt had a pH of 5.26 when the base was 0.123 M and the cation was 0.747 M. Calculate the equilibrium dissociation constant (Kb).
If only COF2 is present initially at a concentration of 2.00 M , what concentration of COF2 remains at equilibrium? Express the molar expression numerically
a platinum electrode is immersed into an aqueous solution of 1m nacl ph7 that issaturated with n2g at s.t.p. i.e.
What volume (in ml) of coffee should be diluted to 25ml prior to analysis using only standard transfer pipets with integer values from 1-10ml
Lime, CaO, is produced by reaction CaCO3(s) CaO(s) + CO2(g). What weight of CaO is obtained by the decomposition of 38.7g of CaCO3.
When might you want to do this. explain what we really are doing in this step and why it could not possibly be to salt-out the product at that point.
A voltaic cell consists of a Mn/Mn2+ electrode (E° = -1.18 V) and a Fe/Fe2+ electrode (E° = -0.44 V). Calculate [Fe2+] if [Mn2+] = 0.050 M and Ecell = 0.78 V at 25°C.
calculate the stoichiometric air-fuel ratio of a fuel blend containing 80 vol.% ethanol and 20 vol.% gasoline
The total pressure for a mixture of N2O4 and NO2 is 1.5 atm. If Kp=7.1 (at 25 degrees C) calculate the partial pressure of each gas in the mixture. 2NO2(g) N2O4(g)
A titration is performed to determine the amount of sulfuric acid, H2SO4, in a 12.00 mL sample taken from car battery. About 50 mL of water is added to the sample, and then it is titrated with 48.62 mL of a standard 0.6403 M NaOH solution
A 30.5-g sample of an alloy at 93.0°C is placed into 50.0 g of water at 22.0°C in an insulated coffee cup with a heat capacity of 9.2 J/K.
What can you conclude from a graph where the plot of ln p (pressure) versus t (time) is linear instead of curved? (for conversion of methyl isonitrile into acetonitrile)
