Question

Using the current coefficients, for the following equation to demonstrate the Law of Conservation of Mass, which molecule is represented by X?
2X→2H2O+O2

Answer 1

X=H2O2, oxygen peroxide, called because people in the past thought it was HO >.<

Answer 2

Oh! Okay. At first I thought it would be H2O3.

Answer 3

If it's H2O3 it wouldn't add up!

2H2O means 4H and 2O
O2 means 2O
and so total is 4H and 4O

If you took H2O3 as X, and 2 of them, it will be like 4H and 6 O!

Answer 4

Ah, I get it now. Thanks!
