Question

what is the empirical formula of this compound? h₂o₂ ho h₂o h₄o₄

Explanation:

The empirical formula is the simplest whole-number ratio of atoms in a compound. For $\text{H}_2\text{O}_2$, the ratio of H to O is 2:2, which simplifies to 1:1 by dividing both subscripts by their greatest common divisor (2). Thus, the empirical formula is $\text{HO}$.

Answer:

HO
