what is the mass in grams of oxygen, is needed to complete combustion of 6 L of methane?
For the incomplete combustion of one molecule of methane (CH4) to form carbon monoxide (CO) rather than carbon dioxide (CO2), one molecule of oxygen (O2) is needed. This results in the equation: CH4 + O2 -> CO + H2O.
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.
To react completely with one molecule of methane (CH4), two molecules of oxygen (O2) are needed. This is because the balanced chemical equation for the combustion of methane is CH4 + 2O2 → CO2 + 2H2O. Each molecule of methane requires two molecules of oxygen to form carbon dioxide and water.
For the combustion of 50 mL methane only 1,05 g oxygen are needed.
Complete combustion is the reaction with oxygen of a material containing at least one of carbon and hydrogen to convert all of the carbon content of the material to carbon dioxide and all of the hydrogen content to water. For methane, CH4 + 2 O2 = CO2 + 2 H2O. But minimum speed range for the CNG vehicle in driving condition should be atleast 50 km per hour for optimum oxygen ratio with methane to achieve complete combustion of CNG
When methane is burned in oxygen, assuming complete combustion, the products are carbon dioxide and water.

The general equation for the complete combustion of a hydrocarbon fuel such as fossil fuels is: hydrocarbon + oxygen → carbon dioxide + water For example, the complete combustion of methane (CH4) would be: CH4 + 2O2 → CO2 + 2H2O.
Oxygen + organic molecule -------> carbon dioxide + water
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.
