Answer

Answer:

The coefficient of $O_2$ is incorrect.

Explanation:

Step1: Balance carbon atoms

For the carbon - containing reactant $C_4H_{10}$ and product $CO_2$, from $2C_4H_{10}$, we have $2\times4 = 8$ carbon atoms on the left - hand side, and $8CO_2$ has 8 carbon atoms on the right - hand side, which is balanced for carbon.

Step2: Balance hydrogen atoms

From $2C_4H_{10}$, we have $2\times10=20$ hydrogen atoms on the left - hand side. In $10H_2O$, we have $10\times2 = 20$ hydrogen atoms on the right - hand side, which is balanced for hydrogen.

Step3: Balance oxygen atoms

On the right - hand side, in $8CO_2$ there are $8\times2 = 16$ oxygen atoms and in $10H_2O$ there are 10 oxygen atoms, so in total there are $16 + 10=26$ oxygen atoms. On the left - hand side, if we assume the coefficient of $O_2$ is $x$, then the number of oxygen atoms is $2x$. Solving $2x=26$ gives $x = 13$. So the correct coefficient of $O_2$ should be 13, not 10.
