A solution of household bleach contains 5.25% sodium hypochlorite, NaOCl, by mass. Assuming that the density of bleach is the same as water, calculate the volume of household bleach that should be diluted with water to make 500.0 mL of a pH = 9.80 solution.
calculate the vapor pressure of a solution of glycerol of 265ml in 3.80x10^2ml of H2O at the normal boiling point of H2O
Calculating Rate and Activation Energy of Diffusion, a) How do I calculate the time that will it take for 0.001 moles of CO2 to leak from a container at steady-state, assuming that the amount of CO in the surroundings is insignificant?
propose two reasons why the results of some of your reactions in this lab do not agree with what is predicted using the established solubility riles.
Which of the following statements is incorrect about benzene?
Gases diffuse faster compared to liquids because of the reason that the liquid molecules A. are held together by stronger inter-molecular forces.
Calculate the pH of a solution prepared by mixing 250. mL of 0.174 m aqueous HF (density = 1.10 g/mL) with 38.7 g of an aqueous solution that is 1.50% NaOH by mass (density = 1.02 g/mL).
The carbohydrate glyceraldehyde is shown below in several different Fischer projections. Sort the structures according to whether the Fischer projection represents glyceraldehyde
If 50 mL of the solution from part a is added to each of the beakers shown here(i through iv), in which beakers, if any, will a precipitate form? State water and mixture is allowed to come to equilibrium
The solubility product of PbBr2 is 8.9 10-6. Determine the molar solubility in the following. (a) pure water
A compound has the empirical formula CH2O. When 0.0866g is dissolved in 1.000g of ether, the solution's boiling point is 36.5 degrees C. Determine the molecular formula of this substance.
Aqueous solutions of each of the following salts {sodium acetate, sodium phosphate, sodium formate, and sodium carbonate} have a pH that is > 7. The reason for this is that the anion undergoes a so-called "hydrolysis reaction".
