Consider the following equilibrium process at 686°C: CO2(g) + H2(g) ? CO(g) + H2O(g) The equilibrium concentrations of the reacting species are [CO] = 0.050 M, [H2] = 0.045 M, [CO2] = 0.086 M, and [H2O] = 0.040 M. (a) Calculate Kc for the reaction at 686°C. (b) If we add CO2 to increase its concentration to 0.50 mol/L, what will the concentrations of all the gases be when equilibrium is reestablished?
If a nonvolatile, yellow crystalline solid sample of 0.351 g is dissolved in benzene (C 6 H 6 ) of 15.8 g formed a solution. this solution freezes at the temperature of 4.77 degree celsius.
How many metric tons of 5%-S coal would be needed to yield the H2SO4 required to produce a 2.5-cm rainfall of pH 2.00 over an area of 100 square kilometers?
Determine how much energy will be required to heat 69.7 gal of H 2 O from 22 degree Celsius to 110 degree Celsius if it is given that 1.00 gal weighs 3.77 kg and water has a specific heat capacity =4.184 J/g C
If each bottle contains 0.358 pint of mouthwash with a density of 0.880g/mL , how many kilograms of alcohol are in 200 bottles of the mouthwash.
Find out How many grams of gasoline will fill a 12.5gal tank if a particular brand of gasoline has the density of 0.737 g/mL at the temperature of 25 degree Celsius?
Consider a cylindrical container partially filled with ethanol (C2H6O). Using the model in which ethanol vapor pressure is a result of equilibrium between the rate of ethanol evaporation and condensation.
Following a terrorist release of Cesium-137 (half-life of 30 years) in downtown, clean up efforts were successful in removing all but 100 curies. How long will it take for the contamination to decay to about 5 curies?
Suppose the volume of this system is compressed to one-half its initial volume and then equilibrium is reestablished. what would be the new equilibrium total pressure.
What is the osmotic pressure of human blood at 37°C if human blood is isotonic to 0.16 M NaCl solution? Remember that NaCl almost completely ionizes in water.
Determine ?H for the formation of one mole of aluminium(III) oxide, Al2O3(s) from the elements?
why we call benzene phenyl and not benzyle when one hydrogen is removed because in case of alkanes we name them alkyl on the removal of one hydrogen atom.
