Explain why complete combustion is desirable?
The advantages of a complete combustion reaction are that they don't release as harmful toxic pollutants. In an incomplete combustion Carbon dioxide, carbon monoxide and carbon is released. A complete combustion only releases carbon dioxide.
What pollutants are released from fossil fuel combustion?
Carbon dioxide, carbon monoxide, nitrogen oxides and sulfur oxides are the pollutants released from fossil fuel combustion.
Combustion as a source of energy can lead to formation of air pollutants like CO and NO and how can each of these pollutants form from the combustion of fuel?
There is carbon and nitrogen in fuel. Burning it with oxygen (incomplete) produces CO and NO.
Is more oxygen used in an incomplete combustion than a complete combustion?
More oxygen is used in a complete combustion.
How does the carbon in fossil fuels get into the atmosphere?
The carbon in fossil fuels is released by burning. This combustion emits carbon dioxide, water and some other pollutants depending on how complete the combustion was. This carbon dioxide, which is slightly heavier than air, become mixed all through the atmosphere by the action of the winds.
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.
Does combustion release oxygen into the atmosphere?
no it burns the oxygen and releases co2 (carbondioxide) among other pollutants
What are pollutants emitted by an internal combustion engine?
carbon monoxide, due to improper combustion Hydrocarbon and nitrogen oxides Also, if the fuel contains sulfur, oxides of sulfur
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 products of combustion of a marshmallow?
If the combustion is complete, carbon dioxide and water.
What does the complete combustion of coal produce?
The complete combustion of organic compounds produces Carbon Dioxide (CO2), Water (H2O), and a residue of any impurities which were present in the coal before combustion. Complete combustion requires a great surplus of molecular Oxygen to occur.
When the weather man says ozone what does he mean?
Usually he means ozone produced by sunlight and infernal combustion pollutants.
