An ethylene glycol solution contains 19.5g of ethylene glycol (C2H6O2) in 87.0mL of water. A) Evaluate the freezing point of the solution. Presume a density of 1.00 g/mL for water. B) Evaluate the boiling point of the solution. Presume a density of 1.00 g/mL for water.
Carbonyl fluoride, COF2, is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF4 via the reaction
Carbon dioxide and water vapor are produced when heptane (C7H16) combusts. How many grams of octane must be combusted in excess oxygen to generate 588-g of CO2
The initial concentrations of four species in an equilibrium are [Cl2] = 1.40 M, [HCl] = 0.100 M, [O2] = 0.300 M and [H2O] = 0.500 M. Is the reaction at equilbrium? If not in what direction must the reaaction shift for the equilibrium to be reache..
