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.

What chemical reactions do both ethane and ethene undergo?
Combustion.
How will we prepare ethane from iodoethane?
The reduction of iodomethane with a mixture of Zinc and hydrochloric acid produces ethane.
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).
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
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
What is the specific enthalpy of combustion of ethane?
-51.88 kJ/g

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! ;)

The reaction for the combustion of methane is?
Reaction of combustion of methane will give off lot of energy. In any combustion reaction there will always be formation of water vapor and heat. Methane + oxygen = combustion reaction.
How many grams of carbon dioxide are produced by the combustion of 224 liters of ethane gas CH in standard conditions?
88
What is the balanced combustion reactions for liquid ethanol?
Combustion of Ethane: 2C2H6+7O2-->4CO2+6H2O Combustion of Ethanol: C2H5OH+3O2-->2CO2+3H2O
What is the balanced equation for the combustion of ethane C2H6 in air oxygen to form carbon dioxide and water?
2C2H6 + 7O2 --> 4CO2 + 6H2O You must have the same total number of atoms of each element on either side of the arrow. To do this, you must use whole-number coefficients (as needed) in front of each reactant and product. They must be expressed in the lowest possible ratio.
