Combustion of alkane will produce

The combustion of an alkane produces carbon dioxide (CO2) and water (H2O). Here are the steps to understand this:

1. Identify the alkane: Alkanes are hydrocarbons, meaning they consist only of hydrogen (H) and carbon (C) atoms. The simplest alkane is methane (CH4).

2. Understand combustion: Combustion is a chemical reaction that occurs in the presence of oxygen (O2), producing heat and light.

3. Write the combustion reaction: For methane, the combustion reaction is CH4 + 2O2 -> CO2 + 2H2O. This means that one molecule of methane reacts with two molecules of oxygen to produce one molecule of carbon dioxide and two molecules of water.

4. Generalize for alkanes: For any alkane CnH2n+2, the combustion reaction is CnH2n+2 + (3n+1)O2 -> nCO2 + (n+1)H2O. This means that one molecule of an alkane reacts with 3n+1 molecules of oxygen to produce n molecules of carbon dioxide and n+1 molecules of water.

So, the combustion of any alkane will produce carbon dioxide and water.
