Question

Balance this equation plz
SO2+O2+H2O------->H2SO4​

Answer 1

Answer: The balanced equation is
`2SO_(2) + O_(2) + 2H_(2)O \rightarrow 2H_(2)SO_(4)`.

Step-by-step explanation:

A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.

For example,
`SO_(2) + O_(2) + H_(2)O \rightarrow H_(2)SO_(4)`

Here, number of atoms present on reactant side are as follows.

• S = 1
• O = 5
• H = 2

Number of atoms present on product side are as follows.

• S = 1
• O = 4
• H = 2

To balance this equation, multiply
`SO_(2)` by 2 and
`H_(2)O` by 2 on reactant side. Also, multiply
`H_(2)SO_(4)` by 2 on product side.

Hence, the equation can be re-written as follows.

`2SO_(2) + O_(2) + 2H_(2)O \rightarrow 2H_(2)SO_(4)`

Now, the number of atoms present on reactant side are as follows.

• S = 2
• O = 8
• H = 4

Number of atoms present on product side are as follows.

• S = 2
• O = 8
• H = 4

Since, the atoms present on both reactant and product side are equal. Hence, the equation is now balanced.

Thus, we can conclude that the balanced equation is
`2SO_(2) + O_(2) + 2H_(2)O \rightarrow 2H_(2)SO_(4)`.
