Answer 2

Answer : The correct answer is $S_8+8O_2\rightarrow 8SO_2$.

Explanation :

Balanced equation : It is defined as an equation for a reaction in which the number of atoms of each element and charge should be same on both the reactant and product sides.

The unbalanced equation is,

$S_8+O_2\rightarrow SO_2$

On the reactant side, there are 8 sulfur atoms and 2 oxygen atoms but on the product side, there are 1 sulfur atom and 2 oxygen atoms. In this reaction, each elements are not balanced. So, for the balance reaction, the reactant side of oxygen and the product side of $SO_4$ multiplied by 8.

Therefore, the balanced equation is,

$S_8+8O_2\rightarrow 8SO_2$
