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

2C2H2 + 5Ocarbon dioxide 4CO2 + 2H2O (l)

 

Best Answer

2C2H2 + 5Ocarbon dioxide4CO2 + 2H2O (l)

2 V 5 V 4 V

From equation, 2 V of C2Hrequires = 5 V of O2

So, for 400ml C2H, 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
