I want you to explain the chemistry in this problem
A student has analyzed several 1 nL volume samples of a 10-12 M solution. What is the expected precision due to Poisson statistics
The selectivity coefficient for a glass electrode is around 10-11. Explain what error in pH is expected for a solution of 0.05 M NaOH
A solution is prepared by dissolving 285 g of sucrose (C12H22O11) in 624 g of water. What is the vapor pressure of this solution at 30°C? (The vapor pressure of water is 31.8 mmHg at 30°C.)
The chemical mechanism of the reaction involves transfer of phosphoryl group to the enzyme, forming a phospho-enzyme intermediate: a His residue is phosphorylated, and H2O hydrolyzes the P enzyme intermediate. Determine the type of mechanism
Suppose that all 175 L of liquid nitrogen in a tank accidentally vaporized in lab that measured 10.00 m X 10.00 m X 2.50 m. What maximum fraction of the air in the room is displaced by the gaseous nitrogen?
The sample requires 48.24 mL of 0.08893 mol/L Na2S2O3 to reach the equivalence point. Assuming that the AU3+ and Li+ ions are unreactive during the titration, determine the mass percent of LiCLO in the sample.
In a titration, a 0.7529 gram sample of a mixture of solid C6H5COOH and solid NaCl is dissolved in water and titrated with 0.150 M NaOH. The equivalence point is reached when 24.78 mL of the base solution is added.
Calculate the molar solubility of barium fluoride in water at 25 degrees celsius. The sp constant for BaF2 at this temperature is 1.0x10^-6.
Silver chloride usually does not ppt in solution of 1.0M NH3. However AgBr has a smaller Ksp. Will AgBr ppt form a solution containing 0.01M AgNO3, 0.01M NaBr and 1.0 M NH3? Ksp = 5 x 10^-13
