Balance the following equation: _ H202 --> _H20+_02
When the equation is balanced, what would be the coefficient in front of H20
Type your answer...

Given :

A chemical equation :

H₂O₂ → H₂O + O₂

Solution :

We can see that there are 2 oxygen atoms in LHS and 3 on RHS .

So, we can reduce the oxygen atoms to two in THS by just dividing it by 2.

H₂O₂ → H₂O + O₂

Now, multiplying both sides by 2, we get :

2H₂O₂ → 2H₂O + O₂

Therefore, the balanced chemical equation is 2H₂O₂ → 2H₂O + O₂ .
