That's not a complete chemical equation. It looks like you're trying to write the balanced chemical equation for the combustion of ethane (C2H6) with oxygen (O2), which produces carbon dioxide (CO2) and water (H2O).

Here's the balanced equation:

2 C2H6 + 7 O2 → 4 CO2 + 6 H2O

Let me break it down:

* C2H6 represents ethane, a hydrocarbon fuel.

* O2 represents oxygen, the oxidant.

* CO2 represents carbon dioxide, a product of combustion.

* H2O represents water, another product of combustion.

The coefficients (2, 7, 4, and 6) balance the equation, ensuring that the number of atoms of each element is the same on both sides of the reaction.
