What is ethanol burned in air balanced equation?
The balanced equation for ethanol (C2H5OH) burned in air is: C2H5OH + 3O2 -> 2CO2 + 3H2O. This equation shows that ethanol reacts with oxygen to produce carbon dioxide and water.
What is the calorific value of methane?
The calorific value of methane is approximately 55.5 megajoules per cubic meter when burned in air.
What is the mole ratio of air to methane gas in the cumbustion of methane?
The balanced chemical equation for the combustion of methane is CH4 + 2O2 -> CO2 + 2H2O. This means that the mole ratio of air to methane gas is 2:1, as two moles of oxygen from the air are required to react with one mole of methane gas.
What is the word equation for methane burning in the air?
The word equation for methane burning in air is: Methane (CH4) + Oxygen (O2) -> Carbon dioxide (CO2) + Water (H2O).
What happens when methane is burnt in air?
When methane is burnt in air, it reacts with oxygen to produce carbon dioxide and water vapor, releasing heat energy in the process. The chemical equation for the combustion of methane is: CH4 + 2O2 → CO2 + 2H2O + heat. This reaction is exothermic, meaning it releases energy in the form of heat.

What is the word equation for methane burned in a Bunsen burner?
No it is not essential. It will burn in air or oxygen if ignited by some spark or match but there are many other ways to get burning in chemistry. The requirements for burning are fuel, oxygen and heat. Oxygen can be supplied by the air for many fires. Heat must often be introduced initially to ignite the fuel but the heat of combustion will then be enough to sustain the burning. Fuel could be methane but there are many other potential fuels in chemistry, for example hydrogen, propane, wood ... Many dry foodstuffs will burn in air if lit.
What is the calorific value of methane?
The calorific value of methane is approximately 55.5 megajoules per cubic meter when burned in air.

When methane is burned in a lime kiln why are the wast gages carbon dioxide and nitrogen?
When methane is burned in a lime kiln, the waste gases are carbon dioxide and nitrogen because methane (CH4) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water vapor (H2O) during combustion. Nitrogen is also present in the air and is not directly involved in the combustion process, so it remains as a waste gas in the form of nitrogen (N2).
What kind of natural gas is siphoned off from some landfills and burned to produce electricity?
Methane is commonly burned at landfills. It is not siphoned; it is a byproduct of decomposing materials inside the landfill. Since methane is lighter than air, it rises from the ground. Burning it keeps the landfill safe and is a great source of energy.
What happens when methane is burnt in air?
When methane is burnt in air, it reacts with oxygen to produce carbon dioxide and water vapor, releasing heat energy in the process. The chemical equation for the combustion of methane is: CH4 + 2O2 → CO2 + 2H2O + heat. This reaction is exothermic, meaning it releases energy in the form of heat.
Does natural gas release nitrogen oxide when burned?
Yes, burning natural gas releases nitrogen oxides (NOx) along with carbon dioxide and water vapor. NOx emissions contribute to air pollution and can have negative impacts on air quality and human health.
What is the balanced equation for the combustion of alkane in air?
The general equation isCnH2n+2 + (1.5n+0.5)O2 -> nCO2 + (n+1)H2OTechnically, that's only really balanced for odd n; for even n you need to double it.
Why do the waste gases contain CO2 and Ni you methane when burned?
When methane is burned, it reacts with oxygen in the air to produce carbon dioxide (CO2) and water vapor. If the methane contains impurities like sulfur compounds, it can produce sulfur dioxide (SO2) as well. The presence of nickel (Ni) in the waste gases might come from the combustion of nickel-containing materials in the environment or from the machinery used for burning the methane.
What happens to methane when burned in little oxygen?
When methane is burned with limited oxygen, incomplete combustion occurs, leading to the formation of carbon monoxide and soot (carbon particles). This results in a less efficient and dirtier combustion process compared to when methane is burned with sufficient oxygen.
