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.

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

The combustion of methane, ch4, releases 890.4kj/mol. that is, when one mole of methane is burned,890.4 kj are given off to the surroundings. this meansthat the products have 890.4 kj less than the reactants. thus, ah for the reaction = - 890.4 kj. a negative symbolforah indicates an exothermic reaction. ch (g) + 20 (g)> co2 (g) + 2 h0 (1); ah = - 890.4 kga) how much energy is given off when 2.00 mol of ch, are burned? b) how much energy is released when 22.4g of ch. areburned?
