I got 2C₂H₂(g) + 5O₂(g) → 4CO₂(g) + 2H₂O for a Acetylene Oxygen Combustion.

A ratio of 2 parts Acetylene and 5 parts Oxygen.

I am trying to calculate the reaction if I am using Air .

I know Air has Nitrogen, Oxygen and other gases. Do I have to factor in the other gases?

Thank you for any help.

Air contains 21% O₂.
But the equation is the same. You need about 5 times more air as 100% oxygen.
