Two different compounds have the formulation CoBr(SO4).5 NH3. Compound A is dark violet, and compound B is red-violet. When compound A is treated with AgNO3(aq), no reaction occurs, whereas compound B reacts with AgNO3(aq) to form a white precipitate.When compound A is treated with BaCl2(aq), a white precipitate is formed, whereas compound B has no reaction with BaCl2(aq).
(a) Is Co in the same oxidation state in these complexes?
(b) Explain the reactivity of compounds A and B with AgNO3(aq) and BaCl2(aq).
(c) Are compounds A and B isomers of one another? If so, which category from Figure 23.19 best describes the isomerism observed for these complexes?
(d)Would compounds A and B be expected to be strong electrolytes, weak electrolytes, or nonelectrolytes?
Using the thermochemical data given for NO2 and N2O4 in class, determine the fraction of N2O4 that will dissociate into two NO2 molecules if one mole of pure N2O4 is introduced to a 10 liter constant volume,
Derive the relationship between the total energy and the molecular partition function for indistinguishable particles.
A 25.00 mL aliquot of iron solution was titrated to equivalence with 26.19 mL of 0.0215 M KMnO4. A procedure similar to the one in experiment 7 was followed. Calculate the moles of iron in the original volumetric flask.
To change the equilibrium constant from Kp to Kc, the value of RT at room temp. (25'C) you would have use is:
a nonelectrolyte compound nbspof 33.8 g is dissolved in 160.0 grams of a solvent that has a normal freezing point 27.7
when deltaG=0; a system is at equilibrium. Use values for delta H standard and delta S standard to determind the temperature
While 0.0044 moles of a weak acid are dissolved in enough water to make 0.500 L, the pH of the resulting solution is 6.10. Calculate Ka. Phenol (C6H5OH, as well called carbolic acid) has a pKa of 9.89. It is utilized to preserve body tissues and is..
Imagine that you have a 6.00L gas tank and a 3.50L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
If the temperatures of a sample of gas is held constant and the volume is 5.0 L at a pressure of 1.0 atm. If the volume is reduced to 2.5 L the new pressure of the gas will be
