What toxic, odorless gas is produced by a running engine?
The complete combustion of hydrocarbons, hexanes for instance, can be represented by the following reaction:
We could represent incomplete combustion by assuming that SOME of the hydrocarbon was combusted to give carbon monoxide:
Alternatively, under conditions of deficient oxygen, some carbon, and some carbon monoxide may be generated:
In terms of oxidation number, what is the difference between
