A 15.0-g sample of a hydrocarbon is placed in a balloon at 1.00 atm and 25°C, and the volume of the balloon is 12.2 L. The hydrocarbon is 79.89% carbon and 20.11% hydrogen by mass. Determine the molecular formula of the hydrocarbon.
What is the total pressure in torr of a gas in a sealed flask that contains oxygen at a partial pres. of 0.41atm and water vapor at a partial pres. of 358mmHg?
During evaporation, molecules escape from the surface of a liquid and enter the gas phase. This physical change requires an energy input: a molecule cannot become gaseous unless it has sufficient energy to break free of its interactions with neigh..
The freezing point depression of water is a rather small 1.86 deg C kg/mol. Addition of 0.454 g of zinc chloride to 3.33 g of water lowers the melting point by 5.2 deg C. Calculate the expected melting point for this mixture and account for any di..
compute the water volume that is released upon its total metabolism to carbon dioxide and H 2 O, taking into account any oxidative phosphorylation that might occur.
The boiling point of pure ethanol is 78 degres celsius .At the first sign of condensing vapors(when maybe just one drop of distillate has been collected) do you think you have pure ethanol?why or why not
What are the values of delta H and delta S for dissolution of PbI2? PbI2 (s) --> Pb^(2+) (aq) + 2I^(-) (aq) You may assume that delta H and delta S are independent of temperature.
For the analyte with pka= 5.6 and 60/40 acetonitrile/water eluent composition what should be the pH of an aqueous portion of the mobile phase to ensure complete ionization
Explain why this compound fails to react as a diels-alder diene- 2 hexagons joined in middle with a double bond in each
Enough of a monoprotic acid is dissolved in water to produce a 1.54 M solution. The pH of the resulting solution is 2.95. Calculate the Ka for the acid.
Which is the correct arrangement of types of radiation when ordered in decreasing energy per photon. a. Radio waves, microwave radiation, ultraviolet light, X-rays
The pKb values for the dibasic base B are pKb1 = 2.1 and pKb2 = 7.8. Calculate the pH at each of the following points in the titration of 50.0 mL of a 0.60 M B(aq) with 0.60 M HCl(aq).
When 76.0 grams of calcium and 36.9 grams of nitrogen gas undergo a reaction that has a 90.0% yield what mass of calcium nitride is formed?
