The balanced equation is:

In this case the coefficient is 2.

I could double everything then it would be 4.

I guess that is what you mean by "standard form"?

The balanced chemical equation for the combustion of **ethane**, or

This means that the coefficient in front of **4** - option **D**.

**SIDE NOTE** *You'll sometimes see this written with fractional coefficients, but the standard form equation has coefficients that are integers for all species involved*.

*don't use this version when asked for standard form*.
