A solution is 0.034M in Na2SO4 and 0.035M in Na2CrO4. Solid Pb(NO3)2 is added without changing the volume of the solution.
A. Which salt will precipitate first?
B. What is the [Pb^2+] when the salt is in (a) first begins to precipitate?
Calculate the maximum non-expansion work that can be done on the surroundings from the combustion per kilogram of H2(g) at constant pressure and 298.15K.
Periodicity in the ionization energy and balancing the equation - Complete the following chemical reactions by writing the product(s) and balancing the equations:
Estimate the triple point pressure and temperature of water, given that the standard enthalpies of fusion and vaporization are 6008 j/mol and 43990 J/h at 273.15k and 298.15 k, respectively the vapor pressure of water at 25 c is 23.8 torr
Cobalt was used as an internal standard to analyze a sample of titanium with atomic absorption spectroscopy. A mixture was prepared by combining a 4.50 mL Ti solution of unknown concentration with 2.00 mL of a 10.5 micrograms/mL solution of Co
Carbon monoxide and water vapor, each at 190 Torr, were introduced into a 250 mL container. When the mixture reached equilibrium at 690 ?C, the partial pressure of CO2(g) was 108 Torr.
C6H5NH3Cl is a cation chloride salt with acid. If 37.1 g of C6H5NH3Cl are dissolved in water to prepare a 150 mL solution, which is the initial molarity of the cation?
Celsius and takes 96 seconds. How long would you expect the reaction to take if ran at 50 degrees Celsius?
Calculate the partial pressure of the hydrogen gas using the atmospheric pressure and the vapor pressure of water at the temperature of the solution. Assuming ideal gas behavior, calculate the number of moles of hydrogen gas evolved.
The well-preserved remains of a now extinct woolly mammoth is entombed in the permafrost lands of Siberia. Scientists have conducted carbon dating experiments on plant debris found in the stomachs of this mammoth.
