In all combustion reactions (other than H2 with O2) CO2(g) and H2O(g) will be produced. CO would NOT be produced, as we are talking about COMPLETE combustion.
Why can't the products be in a form of an oxide and a compound gas?

Is more oxygen used in an incomplete combustion than a complete combustion?
More oxygen is used in a complete combustion.
What are the two main constituents of complete combustion of natural gas and oxygen?
carbon dioxide
A complete combustion always produces which two compounds?
h2o-water and co2 carbon dioxide
Why does excess supply of oxygen lead to complete combustion?
Complete combustion of a hydrocarbon yields carbon dioxide & water; incomplete combustion yields carbon monoxide & water. By having excess oxygen you have enough oxygen to ensure complete combustion. For example the combustion of methane (CH4):complete combustion: CH4 + 2O2 --> CO2 + 2H2Oincomplete combustion: CH4 + 1.5O2 --> CO + 2H2OAs you can see you need a 1/2 mole less of oxygen for the incomplete combustion of methane. So as long as you have twice the amount (in terms of moles) of oxygen as methane you will ensure complete combustion. So anything in excess of that will also ensure complete combustion.
Is the burning of petrol in cars an example of complete combustion or incomplete combustion Explain?
Ideally, complete combustion. In practice it isn't always, which is why cars have catalytic converters.
What are the byproducts from the combustion of coal?
non combustible inorganic matters
Water and black stuff out of the tailpipe?
Water and carbon are byproducts of combustion. Its all good...
What are the two products made during the complete combustion of Paraffin Wax?
water vapour and carbon products of combustion.
What are the types of combustion?
There are two main types of combustion. These are complete, in which the reactant burns in oxygen producing a few reactions, such as carbon dioxide and water. Incomplete combustion occurs when there is not enough oxygen to complete a reaction.

What is the color of flame produced by unsaturated hydrocarbons on complete combustion?
The unsaturated hydrocarbons are mor tangled up so it's harder for the oxygen to get in and break the bonds. Because of this some large sections of the hydrocarbon floats up before being broken, making the flame sooty.
