. 1250cc of oxygen was burnt with 300cc of ethane [C2H6]

1250cc of oxygen was burnt with 300cc of ethane [C₂H₆]. Calculate the volume of unused oxygen and the volume of carbon dioxide formed:

Best Answer

From the equation, 2V of ethane reacts with 7V oxygen.

So, 300 cc of ethane reacts with

Hence, unused O₂ = 1250 - 1050 = 200 cc

From 2V of ethane, 4V of CO₂ is produced.

So, 300 cc of ethane will produce
