a 2L container is charged with 2atm of O2 at 298 Kelvin. Ch4(g) + 2O2(g) --> CO2(g) + 2H20(g) calculate the partial pressure of methane needed to react completely with the O2 in the vessel. What is the total pressure after the reaction is complete if the temperature ...

a mixture of methane CH4 and ethane C2H6 is stored in a container at 294 mmHg. The gases are burned in air to form CO2 and H2O. If the pressure of CO2 is 346mmHg at the same temp and volume as the original mixture, calculate the ratio of moles of CO2 produced to moles of the ...
