Question

water (h₂o) is composed of the same elements as hydrogen peroxide (h₂o₂). how do their properties compare? they have the same properties because they have the same atoms. they have different properties because they have different atoms. they have the same properties because they have the same arrangement of atoms. they have different properties because the arrangement of atoms is different.

Explanation:

The properties of a compound depend on the arrangement of its atoms. Water ($H_2O$) and hydrogen peroxide ($H_2O_2$) have the same elements (hydrogen and oxygen) but different numbers and arrangements of atoms, leading to different properties.

Answer:

They have different properties because the arrangement of atoms is different.
