A gaseous fuel mixture contains 25.3% methane (CH4), 38.2% ethane (C2H6), and the rest propane (C3H8) by volume.
When the fuel mixture contained in a 1.76 L tank, stored at 756 mmHg and 298 K, undergoes complete combustion, how much heat is emitted? (Assume that the water produced by the combustion is in the gaseous state.)
Express your answer with the appropriate units.
This problem requires some literature data:
* Enthalpy of vaporization of water = 41 kJ/mol
* Enthalpy of combustion of methane = -882 kJ/mol
* Enthalpy of combustion of ethane = -1561 kJ/mol
* Enthalpy of combustion of propane = -2220 kJ/mol
Now,
A gaseous fuel mixture contains 25.3% methane (CH4), 38.2% ethane (C2H6), and the rest propane (C3H8)...
A gaseous fuel mixture stored at 745 mmHg and 298 K contains only methane (CH4) and propane (C3H8). When 11.3 L of this fuel mixture is burned, it produces 760 kJ of heat. What is the mole fraction of methane in the mixture? (Assume that the water produced by the combustion is in the gaseous state.)
A) Three gases (8.00 g of methane, CH4, 18.0 g of ethane, C2H6, and an unknown amount of propane, C3H8) were added to the same 10.0-L container. At 23.0 ∘C, the total pressure in the container is 3.90 atm . Calculate the partial pressure of each gas in the container. Express the pressure values numerically in atmospheres, separated by commas. Enter the partial pressure of methane first, then ethane, then propane. B) A gaseous mixture of O2O2 and N2N2 contains...
