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.
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.
Why excess air is provided for combustion?
To ensure complete combustion of the fuel used, combustion chambers are supplied with excess air. Excess air increase the amount of oxygen and the probability of combustion of all fuel
What will happen if the amount of combustion drops?
what will happen if the amount of combustion in earth drops?
Why is combustion reactions an oxidation reactions in small amount?
Combustion is an oxidation reaction - a reaction with oxygen.
Why does complete combustion release more energy than incomplete combustion?
in complete combustion the amount of oxygen is higher/more than the amount of oxygen in incomplete combustion. Heat needs oxygen.
What amount of oxygen is needed for a complete combustion reaction in manipulated variable?

Is carbon monoxide made from a complete combustion?
Carbon monoxide is not the result of a complete combustion.Carbon monoxide is made when hydrocarbons are burnt in low amount of oxygen. That means when partial combustion is happened. Carbon monoxide is harmful to the animals.
What will happen if the amount of combustion drops?
what will happen if the amount of combustion in earth drops?
Why LPG is better fuel than wood?
LPG undergoes complete combustion on burning and produces high amount of energy, but not wood
Why do simple machines do the same amount of work to complete a task as not using the simple machine?
Because the action requires the same amount of force.
What do you mean by calorific value?
The amount of heat energy produced in kilojoules by one gram of a fuel on complete combustion in air or oxygen is called as Calorific value.
How do you regulate the size of a flame when using a Bunsen Burner?
by limiting the amount of oxygen you can get incomplete combustion where the flame is coolest and complete where it goes blue and is bare hot

Combustion is an oxidation reaction - a reaction with oxygen.
