Question

A hydro carbon C10Hx requires 40 moles of O2 for combustion of 2.5moles. Calculate value of" X"

Answer 1

C10Hx + O2 --> CO2 + H2O

Find the whole number ratio of O2 to C10Hx

40/ 2.5 = 16

Balance carbon and oxygen atom

C10Hx + 16 O2 --> 10 CO2 + 12 H2O

Now, the value of x to balance the hydrogen atoms is 24.
