C2H6(g)+nO2→CO2(g)+H2O(l)C_{2}H_{6}(g) + nO_{2} \rightarrow CO_{2}(g) + H_{2}O(l)

In this equation, the ratio of the coefficients of CO2CO_{2}and H2OH_{2}O is**.**

A

1 : 1

B

2 : 3

C

3 : 2

D

1 : 3

Answer

2 : 3

Explanation

Solution

The balanced equation is

2C2H6+7O2→4CO2+6H2O2C_{2}H_{6} + 7O_{2} \rightarrow 4CO_{2} + 6H_{2}O. Ratio of the coefficients of CO2CO_{2} and H2OH_{2}O is 4 : 6 or 2 : 3.
