Predict the magnetic susceptibilities (para- or diamagnetic) and determine the number of unpaired electrons of each of the following complexes (consider C2O42- and H2O as strong field ligands which cause a large splitting of the d-orbitals).
K3[Cr(C2O4)3] * 3H2O
K2[Cu(C2O4)2] * 3H2O
K3[Fe(C2O4)3] * 3H2O
K3[Al(C2O4)3] * 3H2O
Determine the formation constant, Kf, of AC5. Kf=? The solubility of AB(s) in a 1.000-M solution of C(aq) is found to be 0.152 M. What is the Ksp of AB? Ksp=?

what is the pH of a solution made by mixing 30.00mL of .10M acetic acid with 40.00 mL 0f .10M KOH? Assume the volumes are additive and Ka=1.8*10^-5 for CH3CO2H
Draw thw active site of an enzyme that contains a macrocycle coordinated to a transition metal. Explain the function of the enzyme
when .65 moles of iron metal react with 40.0 mL of a 2.5 M copper (II)chloride solution to produce copper metal and iron (III) chloride. How many moles of copper will be produced?
Meaning, use and calculation of empirical formulas, In this introduction are given the explanation of how to find out an empirical formula if one has found out the chemical elements of an unknown substance and measured their ratio of masses
Consider a lake containing 39 ppb (parts per billion) of parathion, which has a log Kow = 3.8. If a sample of lake water was mixed with octanol, what is the expected concentration of parathion in the octanol?
When silver crystallizes, it forms face-centered cubic cells. The unit cell edge length is 408.7 pm. Calculate the density of silver. (Enter answer to three significant figures.)
AgNO3 is mixed with a 230 mL sample of a solution that is .13 M in NaCN. After the solution reaches equilibrium, what concentration of Ag remains?
What is the possible chemical explanation for this? I understand that a reaction using a thiamine catalyst at room temperature for 48 hours may lead to lower yield due to catalyst decomposition, but I'd like to know a more technical explanation.
Determine at what temperature should the reaction be run to get a seventy five conversion of carbon monoxide?
