Answer

Explanation:

Step1: Count oxygen atoms on right - hand side

On the right - hand side, in $3CO_2$, the number of oxygen atoms is $3\times2 = 6$, and in $4H_2O$, the number of oxygen atoms is $4\times1=4$. So the total number of oxygen atoms on the right - hand side is $6 + 4=10$.

Step2: Determine $O_2$ coefficient

Let the coefficient of $O_2$ be $x$. Since each $O_2$ molecule has 2 oxygen atoms, we have $2x = 10$. Solving for $x$, we get $x = 5$.
