Question #62c6b

Answer 1

`2C_2H_6+7O_2->4CO_2+6H_2O`

Explanation:

I'm assuming you are talking about complete combustion ("burns completely") of ethane, in that case it will be

`C_2H_6+O_2->CO_2+H_2O`

To balance it, let's balance the oxygens and hydrogens on the right side first.

`C_2H_6+O_2->2CO_2+3H_2O`

Then, balance the oxygen on the left side.

`C_2H_6+3.5O_2->2CO_2+3H_2O`

There is a fraction with a half, so we can multiply everything by `2`.

`2C_2H_6+7O_2->4CO_2+6H_2O`
