C = Celsius
A sample of pure, gaseous, hydrocarbon is introduced into a previously excavated rigid 1.00L vessel. The pressure of the gas is 0.2atm at a temperature of 127C
a) Calculate the number of moles of the hydrocarbon in the vessel
b) O2(g) is introduced into the same vessel containing the hydrocarbon. After the addition of the O2(g) the total pressure of the gas mixture in the vessel is 1.4atm at 127C. Calculate the partial pressure of O2(g) in the vessel
The mixture of the hydrocarbon and oxygen is sparked so that a complete combustion reaction occurs, producing CO2 (g) and H2O(g). The partial pressures of these gases at 127C are 0.6atm for CO2 (g) and 0.8atm for H2O(g). There is O2(g) remaining in the container after the reaction is complete.
c) Use the partial pressure of CO2 (g) and H2O(g) to calculate the partial pressure of O2(g) consumed in the combustion.
d) Calculate the mass of the hydrocarbon that was consumed
e) As the vessel cools to room temperature, droplets of liquid water form on the inside walls of the container. Predict whether the pH of the water in the vessel is less than, equal too, or greater than 7.
a) n = 0.00609mol
b) 1.20atm of O2
c) 1atm consumed
d) 0.269g of C3H8
e) Less than 7
