How do oxygen conditions differ between complete and incomplete combustion?
Complete combustion has enough oxygen; incomplete combustion occurs when oxygen is limited or mixing is poor.
What products form from carbon and hydrogen during complete combustion?
Carbon forms carbon dioxide; hydrogen forms water vapour.
What three substances can be released during incomplete combustion of a hydrocarbon fuel?
What can unburned hydrocarbons from incomplete combustion contribute to in the atmosphere?
Particulates.
What does sulfur in a fuel form when it reacts with oxygen during combustion?
Sulfur dioxide.
Under what condition should sulfur dioxide be predicted as a combustion product when a fuel burns in oxygen?
When the fuel contains sulfur, either as an impurity or as part of its composition.
How are oxides of nitrogen formed during combustion in air?
High temperatures cause nitrogen and oxygen in the air to react, rather than the oxides simply coming from the fuel.
