What phase is water in in a combustion reaction?

Postby sofiakavanaugh » Mon Mar 12, 2018 8:13 pm

Hi,

There are some homework problems where we have to write combustion reactions, and I know the products are always CO2 and H2O, but is the water in the liquid or gas phase?



Thanks

Water will usually be in its liquid phase because it is occurring at room temperature. CO2 I believe is always in the gaseous state but I think that the problem will usually give you the phase of each of the substances.

It depends. Combustion reactions vary because the definition is vague "hydrocarbons react with O2 to form water and carbon dioxide". I believe often, however, the reactants are all gaseous.
