Determine if a precipitate forms when the following solutions are mixed. Write the overall equation, the total ionic equation, and the net ionic equation. PbNO3(aq) + 2KI (aq)?
For a particular redox reaction MnO2 is oxidized to MnO4- and Ag is reduced to Ag. Complete and balance the equation for this reaction in basic solution
Calculate the molar solubility of AgBr in a 1.00 M aqueous solution of ammonia. Then calculate the solubility of AgBr in pure water, and compare the two solubilities. (Ksp for silver bromide is 7.7x10 -13 and Kf for Ag(NH3)2+ is 1.6x10^7)
The osmotic pressure of 0.010M solutions of a non-voliatile electrolyte solure "a" and a non-volitale non-electrolyte solute "b" are 0.605 atm and 0.235 atm respectively
The atomic weight of Sm is 150.36 and that of Nd is 144.24. The isotopic percentage abundance of 147Sm is 15.0 and that of 144Nd is 23.954.
A solution is made by dissolving 21.7 g of HCl in enough water to make 822 mL of solution. Calculate the pH of the solution at 25 degrees Celsius
Most compounds that contain N-H bonds are basic, but saccharin is acidic
0.150 M HC2H33O2 (Ka=1.8E-5) is titrated with 0.300M NaOH, calculate the pH half way to the equivalence point
How much dry solute would you take to prepare each of the following solutions from the dry solute and the solvent?
How much heat in Joules was lost by the water. How much heat would be lost by the water if 1 mole of KCl had dissolved. c) What is (Delta Heat reaction) in kL/mole for this process, which can be written as KCl (s) --> KCL (aq)
Use the character table to derive which vibrational modes are IR active and which are Raman active
In the formation of diacetylferrocene, the product is always the one in which each ring is monoacetylated. Why is no diacetylferrocene produced in which both acetyl groups are on the same aromatic ring?
We did TLC and column chromatography separating methylene blue and fluorescein. The solvent contained mostly ethanol but also had NaOH, and this NaOH formed SiO- with the silica (the stationary phase), which is in competition with the solvent for ..
