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 + 2H2O
incomplete combustion: CH4 + 1.5O2 --> CO + 2H2O
As 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.

What are the simularities between incomplete and complete combustion?
Both incomplete and complete combustion involve the reaction of a fuel with oxygen to produce energy. They both generate heat and can produce carbon dioxide as a byproduct. However, incomplete combustion typically results in the formation of carbon monoxide and soot due to insufficient oxygen, while complete combustion produces carbon dioxide and water when there is a sufficient supply of oxygen. Thus, while the basic process is similar, the efficiency and byproducts differ significantly.
Is the burning of petrol in cars an example of complete combustion or incomplete combustion Explain?
The burning of petrol in cars is typically an example of complete combustion where petrol (hydrocarbon) reacts with oxygen to produce carbon dioxide and water. However, in some cases, incomplete combustion can occur, leading to the production of carbon monoxide, particulate matter, and unburnt hydrocarbons due to insufficient oxygen supply or improper engine functioning.
What would be the product when combustion reaction occurs in a small tightly-closed container?
If combustion occurs in a small tightly-closed container, the product would likely be carbon dioxide and water vapor. The limited oxygen supply would hinder complete combustion, leading to the formation of these products rather than just carbon dioxide.
Which flame represents complete combustion why?
The blue flame represents complete combustion. This occurs when there is a sufficient supply of oxygen, allowing the fuel to burn efficiently and produce carbon dioxide and water as the primary byproducts. The blue color indicates that the fuel is burning at a higher temperature and that the combustion is more efficient, resulting in less soot and unburned hydrocarbons. In contrast, a yellow or orange flame typically signifies incomplete combustion, where not enough oxygen is present.
How does fire produce carbon monoxide?
When combustion is incomplete due to limited oxygen supply, carbon monoxide (CO) is produced instead of carbon dioxide (CO2). In a fire, if the conditions are not optimal for complete combustion, carbon monoxide is formed as a byproduct.
How combustion of carbon differs in a limited supply of oxygen compared to when oxygen is in excess?
Oxygen in excess: carbon dioxide is obtained.Not sufficient oxygen: carbon monoxide is obtained.
What colour flame would indicate ethane burning in excess oxygen?
A blue flame would indicate ethane burning in excess oxygen. Blue flames are typically associated with complete combustion and sufficient oxygen supply during the burning process.
Why is it better to burn fuels in a good supply of oxygen?
Burning fuels in a good supply of oxygen allows for more complete combustion, resulting in more energy released and less harmful byproducts like carbon monoxide and soot. Insufficient oxygen can lead to incomplete combustion, creating more pollutants and reducing energy efficiency.
How much oxygen is needed to sustain combustion?
Oxygen is required to sustain combustion as it is the oxidizer that allows for the chemical reaction with the fuel. The exact amount of oxygen needed depends on the type of fuel being burned, as different fuels have different oxygen requirements for combustion. In general, combustion requires a sufficient supply of oxygen to ensure complete oxidation of the fuel.

Thus, while the basic process is similar, the efficiency and byproducts differ significantly.
What is sooty and non sooty flame and why it is occurred?
A sooty flame is yellow and produces soot or carbon due to incomplete combustion of fuel. A non-sooty flame is blue and indicates complete combustion, where fuel is completely burnt. The presence of soot in a flame is caused by insufficient oxygen supply or improper fuel-air mixture in the combustion process.

Which type of engine carries its own supply of oxygen?
A rocket has it's own supply of oxygen.
What happens if there is an insufficient supply of oxygen during the combustion of a hydrocarbon?
Like any other hydrocarbons, benzene and methylbenzene burn in a plentiful supply of oxygen to give carbon dioxide, water and oxygen my guess would be that if you didnt have enough in the first place nothing would happen becuase the eqaution of combustion has to be ballance so if thers 2 h2o there has to be to of everthing else or nothing would happen
How does fire produce carbon monoxide?
