Answer

Explanation:

Step1: Balance carbon atoms

For the reaction of butane ($C_4H_{10}$) combustion, the number of carbon - atoms in reactants and products should be equal. In $2C_4H_{10}$, there are $2\times4 = 8$ carbon atoms, and in $8CO_2$ there are also 8 carbon atoms.

Step2: Balance hydrogen atoms

In $2C_4H_{10}$, there are $2\times10=20$ hydrogen atoms. In $10H_2O$, there are $10\times2 = 20$ hydrogen atoms.

Step3: Balance oxygen atoms

In $10O_2$, there are $10\times2=20$ oxygen atoms. In $8CO_2 + 10H_2O$, the number of oxygen atoms is $8\times2+10\times1=16 + 10=26$ oxygen atoms. The correct coefficient for $O_2$ should be 13 to balance the oxygen atoms. So the incorrect part is $10O_2$.

Answer:

$10O_2$
