how are the products of combustion differ when carbon is burn rather than methane?

Answer 1

Carbon exists with a lot of impurities like sulphur etc.So the burning of carbon yields the oxide of these impurities like sulphur dioxide.
Besides the burning of carbon occurs with different supply of oxygen at the burning site such that the end products are 1. Carbon particles (soot) and 2.Carbon monoxide (The deadly gas in more ways than one).3.carbon dioxide 4. watervapour.

Methane, on the other hand, burns with a smokeless blue flame in a plentiful supply of oxygen to give carbon dioxide and watervapour.
In a reduced supply of oxygen Methane burns with a yellow flame and the products are 1.carbon monoxide 2. unburnt carbon particles and 3. carbon dioxide 4. watervapour.

The advantage of burning methane is that the amount of methane can be adjusted to be sufficient for the oxygen available.

Answer 2

Burning methane will yield carbon dioxide AND water vapor
Burning carbon will only create carbon dioxide.
C + O2 ---> CO2
or
CH4 + 2 O2---> 2 H2O + CO2

the difference lies in the fact that you need to deal with the hydrogen in the hydrocarbon.

Answer 3

Burning methane will yield carbon dioxide and water vapour
Burning carbon will only create carbon dioxide.
C + O2 ---> CO2
or
CH4 + 2 O2---> 2 H2O + CO2
Carbon is not available in pure from generally. It leaves ash and hydrogen as well.

Answer 4

I study someplace that burning methane (to run a motor vehicle) is extra ideal than letting it go obviously into the ambience. and that i recognize for a undeniable reality that a methane-burning motor vehicle pollutes a best purchase less than a gas-burner. i recognize this because I actual have a replica of the emissions try from my 1999 Ford Crown Victoria, which runs on organic gas in effortless words (methane), and it pollutes way, way less than a similar motor vehicle that runs on gas. it is also fantastically cool to be waiting tochronic round and by no skill use a drop of gas, ever, pollute a lot less, and save gobs of money collectively (organic gas is at the moment 97 cents a gallon the position I stay). in simple terms my 2 cents on the placement...

Answer 5

Burning pure carbon gives carbon dioxide.

If you burn a hydrocarbon such as methane you get carbon dioxide and water as hydrocarbons contain hydrogen

Answer 6

When carbon is burnt in a plentiful supply of oxygen, carbon dioxide is formed. When it is burnt in a limited supply of oxygen, carbon monoxide is formed.

The products of combustion of methane are carbon dioxide and water

Answer 7

Carbon - C
Methane - CH4

C + O2 --> CO2
or if there is a limited amount of oxygen, 2C + O2 --> 2CO.

CH4 + O2 --> CO2 + 2H2O
Similarly, if there is a limited amount og oxygen,
2CH4 + 3O2 --> 2CO + 4H2O
or even,
CH4 + O2 --> C + 2H2O
