Natural gas is typically about 95% methane. The other 5% is a complex mixture of other hydrocarbons (percent by mass). Let’s assume the 5% is all ethane, C2H6. Balance and calculate the heat of combustion of ethane, ∆Hcomb (kJ/mole), using reaction below.
C2H6 (g) + O2 (g) → CO2 (g) + H2O (g)

Natural gas is mostly methane, but it also contains some ethane and propane. The enthalpies of combustion of methane, ethane and propane are -810, -1420, and -2030 kJ mol-1, respectively. (A) Complete the chemical reactions for the combustion of these fuels and calculate the amount of heat released per mole of oxygen and carbon dioxide produced for the three gases using the enthalpy of the reaction. i.

The combustion of methane (natural gas) is given by the equation: CH4 (g) + 2 O2 (g) → CO2 (g) + 2 H2O (g) ΔH = -890 kJ How much heat (in kJ) is released by the reaction of 48.5 grams of O2 with excess CH4? Remember that if heat is given off, is negative, and should be entered as such)
Consider our dear friend, the combustion of methane/natural gas: CH4 (g) + 2 O2 (g) → 2 CO2 (g) + H2O (l) ΔHreaction = -802.3 kJ/mol If 1.50 mol O2 are consumed, how much heat is produced by this reaction?

Using the standard molar heat of combustion of hydrogen, methane, and ethane (given below), find the enthalpy change for 2CH4(g) → C2H6(g) + H2(g) H2 + ½ O2 → H2O ΔHo = -285.8 kJ CH4 + 2O2 → CO2 + 2H2O ΔHo = -890.4 kJ C2H6 + (7/2)O2 → 2CO2 + 3H2O ΔHo = -1559.9 kJ
To simulate Natural gas mixture over water, 10 moles of methane (CH4) and 1 mole of ethane (C2H6) were injected into a 30.0 L cylinder at a temperature of 30.0 oC? One third of this cylinder is filled with water so remaining volume is left for the binary gas mixture. Answer the following: (i) Calculate mole fractions Xmethane and Xethane ? Hence calculate the, (a) molar Gibbs free energy-change of mixing ΔGm? (b) molar entropy-change of mixing ΔSm? (ii)With both...
A mixture of methane gas, CH4(g), and pentane gas, C5H12(g), has a pressure of 0.5427 atm when placed in a sealed container. The complete combustion of the mixture to carbon dioxide gas, CO2(g), and water vapor, H2O(g), was achieved by adding exactly enough oxygen gas, O2(g), to the container. The pressure of the product mixture in the sealed container is 2.417 atm. Calculate the mole fraction of methane in the initial mixture assuming the temperature and volume remain constant.
A mixture of methane (CH4) and ethane (C2H6) of mass 31.16 g is completely burned in oxygen. If the total mass of CO2 and H2O produced is 150.19 g, calculate the mass fraction of CH4 in the mixture.
Natural gas (mostly methane, CH4) is very abundant in many Middle Eastern oil fields. However, the costs of shipping the gas to markets in other parts of the world are high because it is necessary to liquefy the gas, which has a boiling point of −164 ∘C. One possible strategy is to oxidize the methane (in a 1:1 mole ratio) to methanol, CH3OH, which has a boiling point of 65 ∘C and can therefore be shipped more readily. Part A)...
