A1.738 g sample of a component of the light petroleum distillate called naphtha is found to yield 5.327 g co2(g) and 2.544 g h2o(l) on complete combustion.
this particular compound is also found to be an alkane with one methyl group attached to a longer carbon chain and to have a molecular formula twice its empirical formula.
the compound also has the following properties:
melting point of −154 ∘c ,
boiling point of 60.3 ∘c ,
density of 0.6532 g/ml at 20 ∘c ,
specific heat of 2.25 j/(g⋅∘c) , and
δh∘f=−204.6kj/mol .
part c
calculate the enthalpy of combustion, δh∘comb, for c6h14. you'll first need to determine the balanced chemical equation for the combustion of c6h14.
express your answer to four significant figures and include the appropriate units.
