Question

The combustion of ethane in the presence of excess oxygen yields carbon dioxide and water.

Answer 1

Answer:

C₂H₆ + 3.5O₂ -> 2CO₂ + 3H₂O

For complete combustion, use the following trick for your ease:

$C_{x}H_{y} + O_{2} -> xCO_{2} + \frac{y}{2}H_{2}O$

Then you can simply count the moles of oxygen
