. What volume of oxygen would be required to burn completely 400 ml of acetylene [C2H2]

What volume of oxygen would be required to burn completely 400 ml of acetylene [C₂H₂]? Also calculate the volume of carbon dioxide formed.

2C₂H₂ + 5O₂4CO₂ + 2H₂O (l)

Best Answer

2C₂H₂ + 5O₂4CO₂ + 2H₂O (l)

2 V 5 V 4 V

From equation, 2 V of C₂H₂requires = 5 V of O₂

So, for 400ml C₂H₂, O₂ required = 400 ×5/2 =1000 ml

Similarly, 2 V of C₂H₂ gives = 4 V of CO₂

So, 400ml of C₂H₂ gives CO₂ = 400 ×4/2 = 800ml
