a.) Write the balanced complete combustion reaction for ethane (C2H6), producing CO2 and water vapour. Make sure to include phases. Also, make sure that the stoichiometric coefficients are whole numbers and are not fractions.

Question

b.) What is the enthalpy of reaction (ΔH°rxn), in kJ, for the process in part (a)?
c.) Calculate the heat (q), in kJ, produced when 265.0 g of ethane burns completely.
d.) Write the balanced incomplete combustion reaction for ethane (C2H6), producing CO and water vapour. Make sure to include phases. Also, make sure that the stoichiometric coefficients are whole numbers and are not fractions.
e.) What is the enthalpy of the reaction (ΔH°rxn), in kJ, for the process in part (d)?
f.) Calculate the total heat (q), in kJ, produced by 265.0 g of ethane when 6.00% by mass of it burns incompletely and the remainder burns completely.

(...I tried so hard to do these questions, but I just can't do them! Please explain the steps, please!

Answer 1

2C2H6 + 7O2 ==> 4CO2 + 6H2O
b.
dHrxn = (n*dHf products) - (n*dHf reactants)

c.
q = dHrxn from b x (265g/2*molar mass C2H6)

d.e.f. Follow a,b,c steps.
Post your work if you get stuck.

Answer 2

What is the difference between writing a COMPLETE and an INCOMPLETE equations in a) and d)?

Answer 3

whats the chemical eqn for the combustion of ethane to form CO tho
