8. 2500 cc of oxygen was burnt with 600 cc of ethane [C HCalculate the volume of unused oxygen and the volume ofcarbon dioxide formed, after writing a balanced equation:Ethane + Oxygen → Carbon dioxide + Water vapour

Answer»

2 C2H6 + 7 O2 --->4 CO2 +6 H2O

ethane rqd = 2volumeoxygen rqd = 7 volumetherefore for 600 cc of ethanevolume of oxygen rqd = 300 x 7 cc = 2100 ccvolume of carbon dioxide formed will be = 4 volume = 4 x 300 cc = 1200 ccvolume of unused oxygen left = 2500 - 2100 =400 cc
