Calculate the ph at the equivalence point for the following titration 0.20M HCl versus 0.20M methylamine (CH3NH2). The Ka of methylammonium is 2.3x10^-11.
You perform column chromatography on a mixture of reaction products which shows two spots on TLC. However, under the column conditions you chose those two compounds do not separate.
A reaction that is used to propel rockets is N2O4(l) + 2N2H4(l) --> 3N2(g) + 4H2O(g). This reaction has the advantage that neither product is toxic, so no dangerous pollution is released.
A 300.0-mL saturated solution of gold (II) phosphate, contains 0.31 grams of dissolved salt. a. Write an equilibrium expression for the solubility product constant.
what is the equilibrium partial pressure of water vapor above a mixture of 44.0 g H2O and 56.0 g CHOCH2CH2OH at 35 Degree C. The partial pressure of pure water at 35.0 degree C is 42.2 mmHg. Assume ideal behavior for the solution.
A solution of 75.0 g of benzene (C6H6) and 75.0 g of toluene (C7H8) has a total vapor pressure of 80.9 mmHg at 303 K. Another solution of 100.0 g benzene and 50.0 g toluene has a total vapor pressure of 93.9 mmHg at this temperature.
Write a formula for the conjugate base formed when each of the following behaves as a bronzed acid.
Suggest a chemical test that would allow you to distinguish between tert-butyl alcohol and 1 butanol, both of which give a positive ceric nitrate test?
4-chloro-1,4-dimethylhexanol is treated with heat, please show products
A solution is prepared by dissolving 75.0 g HCl(g) in enough water to make 350.0 L of solution. The ph of this solution is?
Acid strength decreases in the series HI > HSO4- > HF > HCN. Which of these anions is the weakest base?
Does anyone know the balanced equation piperonaldehyde (C8H6O3)+ acetophenone (C8H8O)= 3,4-methylenedioxychalcone(C16H12O3)
