Ethane (C2H6) is a colorless, odorless gas that is highly flammable. The UNBALANCED chemical equation for the combustion of ethane is written below: C2H6(g) + O2(g) → CO2(g) + H2O(g) Balance this chemical equation so that the smallest whole number coefficient appears in front of each substance. Then, use your balanced equation and the standard enthalpies of formation provided below to calculate the standard enthalpy change, (ΔH°, in kJ) for the reaction. Substance ΔHf° (kJ/mol

Question
Ethane (C2H6) is a colorless, odorless gas that is highly flammable. The UNBALANCED chemical equation for the combustion of ethane is written below:
C2H6(g) + O2(g) → CO2(g) + H2O(g)
Balance this chemical equation so that the smallest whole number coefficient appears in front of each substance. Then, use your balanced equation and the standard enthalpies of formation provided below to calculate the standard enthalpy change, (ΔH°, in kJ) for the reaction.
Substance | ΔHf° (kJ/mol) |
CO2(g) | –393.51 |
C2H2(g) | +227.4 |
C2H4(g) | +52.4 |
C2H6(g) | –84.0 |
O2(g) | 0 |
H2O(l) | –285.83 |
H2O(g) | –241.82 |
