What is minimum concentration of oxygen required for combustion?
The minimum concentration of oxygen required for combustion is typically around 16% in air. Below this level, the fuel will not be able to sustain a flame or combust.
Combustion is the rapid reaction between what?
Oxygen and a compound (or a mixture of compounds) able to burn.
Is oxygen required in combustion?
Yes, oxygen is required for combustion to occur. During combustion, oxygen reacts with the fuel in the presence of heat to produce energy in the form of heat and light. This chemical reaction is known as oxidation.
Is moecular oxygen a reaction during a combustion?
No. Molecular oxygen is a reactant in a combustion reaction.
Is oxygen one result of combustion?
Yes, oxygen is used as a reactant in combustion reactions and is often depleted during the process as it combines with other elements to form combustion products such as carbon dioxide and water vapor. These combustion products contain the oxygen atoms that were part of the original reactant.
How hot does oxygen burn and what are the factors that influence its combustion temperature?
Oxygen itself does not burn, but it supports combustion. The temperature at which oxygen supports combustion varies depending on the material burning. Factors that influence combustion temperature include the type of material, the amount of oxygen present, and the efficiency of the combustion process.
How can oxygen produce combustion?
Oxygen is a required reactant in a combustion reaction - without oxygen, you do not have combustion. If you combine a hydrocarbon with oxygen and add heat, you will cause a combustion reaction that results in carbon dioxide and water being formed (provided there was complete combustion).
What happens to burning candle if there is no oxygen?
If there is no oxygen, a burning candle will not be able to sustain the combustion process since oxygen is needed for the flame to continue burning. The candle will eventually go out in the absence of oxygen.
What gas from the air is needed for combustion?
the three essentials for combustion are :- (i) combustible substance (ii) oxygen (iii) ignition temperature
Does combustion remove oxygen from air?
Yes, combustion is a chemical reaction that consumes oxygen as it oxidizes the fuel. This process leads to the removal of oxygen from the air in the immediate vicinity of the combustion reaction.
What percentage of oxygen for fire?
Oxygen comprises about 21% of the air we breathe. For combustion to occur, the oxygen level needs to be around 16% or higher. If the percentage drops below that, a fire will be deprived of oxygen and will not be able to sustain itself.
Is more oxygen used in an incomplete combustion than a complete combustion?
Yes, more oxygen is used in incomplete combustion compared to complete combustion because incomplete combustion results in the partial burning of the fuel, leading to the formation of more byproducts like carbon monoxide and soot. This requires additional oxygen to combine with these byproducts, using up more oxygen overall.
