Question

For balancing the given chemical equation, if the coefficient of CxHy is 4, the coefficient of O, is :
CxHy + 02 - CO2 + H2O
(1) 4x + y
(2) 4x + 4y
(3) 2x + y
(4) 2x + 2y​

Answer 1

Answer:

Formula for balancing a general combustion reaction is-

CxHy + (x+y/4)O2 ---> xCO2 + (y/2) H2O

So, we can see that -

When coefficient of CxHy is 1, coefficient of O2 is (x+y/4)

When coefficient of CxHy is 4, coefficient of O2 will be 4(x+y/4)= 4x+y

Hence, the right answer is Option 1 that is 4x+y
