Question

1 volume of gaseous compound consisting C, H and O on complete combustion in the presence of 2.5 volume of O2 gives 2 volume of steam and 2 volume of CO2.  The formula of the compound is (all the measurements are made under similar conditions ​

Answer 1

Explanation:

CxHyOz+2.5O2=2H2O+2CO2

total no. of C in product =2

i.e.x=2

total no. of H=4

i.e.y=4

z=0

therefore formula C2H4
