The Gibbs free energy change is calculated from the expression Δ G = Δ H - T(Δ S) For the combustion of ethene (assuming it takes place at 25oC): C2H4 + 3O2 --> 2CO2 + 2H2O you need to find the enthalpy and entropy changes, which are Δ H (combustion) = - 1400 kJ/mol Δ S (combustion) = - 1102 J/mol/K Substituting into the first equation, remembering to divide the entropy value by 1000 because it's in J per mol per kelvin, not kJ, and converting the 25 degrees C to kelvin, we get: Δ G = -1314.35 kJ http://www.docbrown.info/page07/delta3SGc.htm
What else can I help you with?
What is the specific enthalpy of combustion of ethane?
The specific enthalpy of combustion of ethane is approximately -1560 kJ/mol.
What is the chemical formula for ethane burns?
The chemical formula for ethane is C2H6. When ethane burns, it reacts with oxygen to produce carbon dioxide (CO2) and water (H2O) as products. The balanced equation for the combustion of ethane is: 2C2H6 + 7O2 -> 4CO2 + 6H2O.
Would you expect the following equation to represent the mechanism by which ethane burns?
No, the equation provided is not balanced and does not correctly represent the mechanism by which ethane burns. The complete combustion of ethane is typically represented as C2H6 + 7/2 O2 -> 2 CO2 + 3 H2O.
What is the balanced equation for the combustion of ethane?
ethane + Oxygen --> Carbon dioxide + Water
Ethane plus oxygen equals carbonmonoxide plus water?
The balanced chemical equation for the reaction is: 2 C2H6 + 7 O2 -> 4 CO + 6 H2O. This reaction represents the combustion of ethane where ethane reacts with oxygen to produce carbon monoxide and water.

What is the energy change associated with the combustion of c2 h4?
i at first wrote out the enthalpies of combustion for hydrogen ethene and ethane and then manipulated the equations , ultimately my answer ended up being -137 but when i tried to find out the enthalpy on google it just came up this quiestion did you find out what the answer was!?
Can ethane be broken down by chemical change?
Yes. Ethane can undergo combustion, in which it reacts with oxygen to produce carbon dioxide and water. 2C2H6 + 7O2 --> 4CO2 + 6H2O
Can ethane be broken down by a chemical change?
Yes. Ethane can undergo combustion, in which it reacts with oxygen to produce carbon dioxide and water. 2C2H6 + 7O2 --> 4CO2 + 6H2O
What is the word equation for a incomplete combustion?
Incomplete combustion of a hydrocarbon typically produces carbon monoxide and water vapor. The word equation for incomplete combustion of ethane, for example, is: ethane + oxygen → carbon monoxide + water
What is the chemical formula for ethane burns?

Are there gases which support combustion and are also supporters of combustion?
Yes there are. These gases are hydrogen,methane,ethane,propane,butane,pentane. Hope this helped! ;)

What is the amount of heat released in the combustion of 1mol of ethane if 6.0g produces 312KJ?
You can approach this from a stoichiometry perspective or a proportions perspective. Before you do one of these methods, you want to calculate the molar mass of ethane. Ethane has two carbons and six hydrogens. Using the periodic table, we find that the molar mass is 30.06 g/mol. If you do the stoichiometry, we have (1 mol)×(30.06 g/mol)×(312 kJ / 6.0 g) = 1600 kJ. Or you can say that if 6.0 g = 312 kJ, then 30.06 g = x kJ where "x" is your unknown, or (6 g / 312 kJ) = (30.06 g / x kJ). Solving for x provides 1600 kJ. Both involve the same calculations but have slightly different modes of thinking. Note that the answer has only two significant digits because 6.0 has only two significant digits. We can assume that 1 mole is a discrete value and that our answer shouldn't have one significant digit.

How many carbon dioxide molecules will be formed in two ethane molecules?
Ethane does not have any molecule of carbon dioxide. However when ethane undergoes combustion then two molecules of carbon dioxide are formed (as ethane contains two carbon atoms).
