Answer
Explanation:
Step1: Balance carbon atoms
There are 2 carbon atoms in $C_2H_6$. So, to balance carbon in $CO_2$, the coefficient of $CO_2$ should be 2. $C_2H_6+\ O_2\rightarrow\ H_2O + 2CO_2$
Step2: Balance hydrogen atoms
There are 6 hydrogen atoms in $C_2H_6$. So, the coefficient of $H_2O$ should be 3 to balance hydrogen. $C_2H_6+\ O_2\rightarrow3H_2O + 2CO_2$
Step3: Balance oxygen atoms
On the right - hand side, there are 3 oxygen atoms in $3H_2O$ and 4 oxygen atoms in $2CO_2$, making a total of 7 oxygen atoms. So, the coefficient of $O_2$ should be $\frac{7}{2}$. But we usually use whole - number coefficients. Multiply the entire equation by 2 to get whole - number coefficients. $2C_2H_6 + 7O_2\rightarrow6H_2O+4CO_2$
