I think what you are thinking of is the decomposition of Hydrogen peroxide, which has the equation:

2H2O2 --> O2 + 2H2O which when balanced then equals 8.

2(H2O2) --> 2H2O +O2

|4*2|=8 -->|3*2|=6 +2= 8

That is the entire equation completed and balanced. Hope it helped!

Is H2O2--H2O plus O2 a balanced equation?

No. There are two O's on the right side and three on the left. The balanced form is 2 H202 -> 2 H20 + 02. All of the O's are the letter 0 in this equation. All numbers are subscripts except the two 2's in front of the H's that have a space after them. I've taken college-level chemistry, so I remember how to do this.

In the chemical equation H2O2(aq)-H2O(1) plus O2(g)then H2O2 is a?

If you had the equation of H2O2(aq) ==> H2O(l) + O2(g), it wouldn't be balanced, so is incorrect. If it were 2H2O2 ==> 2H2O + O2, then it would be balanced, and H2O2 would be an example of a disproportionation reaction, where H2O2 is both the oxidizing and reducing agent, i.e., the O is both oxidized and reduced to form H2O and O2. Not sure if this is what you are looking for as the question is rather vague.
