Combustion of liquids

Postby AtreyiMitra2L » Tue Jan 23, 2018 5:28 pm

Hello! When a liquid combusts, will liquid water be produced and not gaseous water? Does this always happen? I am asking this specifically in reference to num 93 in which the combustion of c6h6 seems to produces liquid water. Thanks!

Hi!
The book states that "the products of the combustion of an organic compound are carbon dioxide gas and liquid water." (on page 291).
Additionally, the example given on page 297 shows that liquid water is produced in result of a combustion reaction.

So I think that in general, regardless of the physical state of the substance that is being combusted, the products should be : CO2(g) and H20 (l).

Also, in combustion, it's almost always the vapor burning- not the liquid.

In combustion reactions, the products normally come in the form of gaseous CO2 and liquid H20, unless otherwise specified.

It's usually liquid H2O because the temperature of the reactions in our homework problems is stated or assumed to be 25 degrees Celsius
