When an hydrocarbon is burned in excess oxygen, the products are:?

Question

a) CO and H2O b). CO2 and H2O c)CO2 only d)H2O only e. none of these

Answer 1

b)...CO2 + H2O.
(The excess oxygen only ensured complete combustion).

Answer 2

based on the previous answer, there are 2 mols of C (from 2 mols of CO2) and 3 mols of H (from a million.5 mols of H2O) that would desire to desire to have come from the hydrocarbon. using actuality rely would be unable to be destroyed, basically converted, this 2:3 element ratio might desire to exist indoors the hydrocarbon 's formulation. the only compound indoors the above checklist that meets this qualification is C4H6 (answer D)......4 C's/6 H's = 2 C's/3 H's you would be valuable that it particularly is the biggest outstanding answer via ability of writing out the combustion reaction and balancing it: 2 C4H6 + eleven O2 ----------> 8 CO2 + 6 H2O (a million mol C4H6 / 4 mols CO2) * 2 mols CO2 = 0.5 mols C4H6 fed on in reaction MW of C4H6 = 4(12) + 6(a million) = fifty 4 g/mol 27.0 g of C4H6 = 27/fifty 4 = 0.5 mols

Answer 3

b) Look at the chemical formulae:
H2C? + O2 = H2O + CO2

Answer 4

h2o and co2

Answer 5

b).

Two points!
