If 15.0 mL of 0.200 M calcium nitrate are mixed with 15.0 mL of 0.300 M potassium hydroxide, how many moles of calcium hydroxide will be expected to be made?
What is the the structures of both products and how can you distinguished them using IR spectroscopy?
The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted
When 2-propanol was used as the developing solvent, two substances moved with the solvent front (Rf = 1) during TLC analysis on a silica gel plate. Can you conclude that they are identical? If not, what additional experiment would you perform?
When 50.0 mL of 0.50 M formic acid is titrated with 0.50 M sodium hydroxide, calculate the pH for each of the following: Ka of formic acid = 1.8 x 10^-4 Be sure to account for volume changes at each step.
A sample of 0.0020 mole of HCl is dissolved in water to make a 2000mL solution. Calculate the molarity of the HCl solution, the {H3O}, and the pH.
Styrene, phenylethene, is treated with H3PO4, an acid whose conjugate base is a poor nucleophile.
A solution of ethanol (C2H5OH) in water is prepared by dissolving 87.0 mL of ethanol (density = 0.79 g/cm3) in enough water to make 250.0 mL of solution. What is the molarity of the ethanol in this solution?
What volume of 2M H2S , in L, is required to react with excess O2 to produce enough SO2 to fill a cylinder that is 51ft long and has a diameter of 7ft at a pressure of 464 torr and 30 AC?
How many different signals are expected for this molecule? That is, how many magnetically different hydrogens are present in the molecule? This is in general determinted by differences in bonding, and distance to an electronegative group.
