Write the balanced equations for the following reactions : * (ii) `SO_(2_((g)))+H_(2)S_((aq))rarrS_((s))+H_(2)O_((1))`

Explanation

Step 1 : Rewrite the given equation as it is
`SO_(2_((g)))+H_(2)S_((aq))rarrS_((s))+H_(2)O_((1))`
Step 2 : Write the number of atoms of each element in the unbalanced equation on both sides of equations.

The number of hydrogen atoms on both sides of the equation are same , therefore , equalise the number of sulphur atoms and oxygen atoms.
Step 3 : To balance number of sulphur atoms :

To equalise the number of sulphur atoms , we use as the factor in the product , now the equation becomes
`SO_(2)+H_(2)Srarr2S+2H_(2)O`
Step 4 : To equalise the number of oxygen atoms the unbalance equation.
ltbgt To equalise the number of sulphur atoms, we use 2 as the factor in the product i .e `H_(2)O` , now the unbalanced equation becomes
`SO_(2)+2H_(2)Srarr2S+2H_(2)O`
Now , count the atoms of each element on both sides of the equation ,there are less number of sulphur atoms in the product . Now equalise the sulphur atoms , the balanced equation becomes,
`SO_(2)+H_(2)Srarr3S+2H_(2)O`
Now indicate the physical states of reactants and products.

`SO_(2_((g)))+2H_(2)S_((aq))rarr3S_((s))+2H_(2)O_((1))`
