Question

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

Answer 1

C₂H₆ + 3.5O₂ -> 2CO₂ + 3H₂O

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

`C_(x)H_(y) + O_(2) -> xCO_(2) + (y)/(2)H_(2)O`

Then you can simply count the moles of oxygen
