Water treatment plants commonly use chlorination to destroy bacteria. a byproduct is chloroform- CHCl3, a suspected carcinogen. This is produced when HOCl, formed by reaction of Cl2 and water, reacts with dissolved organic matter. There is a limit of 100 ppb for CHCl3 in drinking water. Convert this concentration to mass percent.
A sample of argon gas at a pressure of 0.981 atm and a temperature of 29.7oC, occupies a volume of 12.5 liters. If the gas is allowed to expand at constant temperature to a volume of 19.1 liters, the pressure of the gas sample will be
4.41-g sample of a salt dissolves in 9.10 g of water to give a saturated solution at 25°C. What is the solubility (in g salt/100 g of H2O) of the salt.
Ammonium nitrate (NH4NO3) decomposes into nitrogen, oxygen, and water. If 12g of ammonium chloride decompose entirely at 300 C with delta H reaction =-236.kJ
Choose the selection which correctly identifies the forces which must be overcome to convert NH3 from a liquid to a gas. a) Only London dispersion forces must be overcome. b) Only dipole-dipole forces must be overcome
What is the molar concentration of Cl- in solution? What is the molar concentration of Na+ in solution. What is the molar concentration of OH- in solution
Assuming levels of atmospheric CO2 are 390 ppm CO2, what is the pH of rainwater in equilibrium with the atmosphere for the pre-industrial atmospheric CO2 concentration of 280 ppm,v.
calculate the volume of 0.1205 M NaOH that will neutralize 10.0 mL of 3.8% (by mass) citric acid solution.Assume the density
For the equilibrium PCl5(g) PCl3(g) + Cl2(g), Kc = 2.0 × 101 at 240°C. If pure PCl5 is placed in a 1.00-L container and allowed to come to equilibrium, and the equilibrium concentration of PCl3(g) is 0.13 M, what is the equilibrium concentration o..
Calculate the vapor pressure of the solver over the solution at 25 degrees C. The vapor pressire of pure water at 25 degrees C is 23.8 mm Hg
Write the equations for the following reversible systems A) solid KMnO4 in a saturated aqueous solution of KMnO4 B) a mixture of solid and gaseous forms of CO2 in a closed container
What weight of A would be removed from a solution of 10g of A in 100mL of water by a single extraction with 100 mL of hexanes? What weight of A would be removed by four successive extraction with 25-mL portions of hexanes?
The instruction booklet for your pressure cooker indicates that its highest setting is 12.5 psi . You know that standard atmospheric pressure is 14.7psi
