When ethane burns in air, the products formed are carbon dioxide (CO2) and water (H2O), along with the release of heat and light. The balanced chemical equation for the combustion of ethane in air is:

C2H6 + 7O2 -> 2CO2 + 3H2O

This reaction is an example of complete combustion, where ethane reacts with oxygen to produce carbon dioxide and water. The heat and light released during this exothermic reaction make it a useful source of energy.

When ethane reacts with potassium, it does not undergo https://bbgate.com/tags/nitroethane/ a direct reaction. Ethane is a hydrocarbon, and potassium is a highly reactive metal. The reaction between them is not favorable under normal conditions.

However, it's worth noting that potassium can be used as a reducing agent in the synthesis of ethane. For example, ethyl iodide can be reduced to ethane using potassium metal. This reduction reaction involves the replacement of the iodine atom in ethyl iodide with hydrogen from the potassium metal.

C2H5I + 2K -> C2H6 + 2KI

This reaction is an example of a metal-mediated reduction, where the metal (potassium) acts as a reducing agent to convert the organic compound (ethyl iodide) into the desired product (ethane).

It's important to handle potassium with caution due to its reactivity, and such reactions should be carried out under appropriate laboratory conditions.
