No, H₂O (water) and H₂O₂ (hydrogen peroxide) do not have the same properties. They are distinct chemical compounds with different structures, physical properties, and chemical reactivity.

Here's a table summarizing the key differences:

| Property | H₂O (Water) | H₂O₂ (Hydrogen Peroxide) |

|---|---|---|

| Structure | Two hydrogen atoms bonded to one oxygen atom | Two hydrogen atoms bonded to two oxygen atoms |

| State at room temperature | Liquid | Liquid |

| Boiling point | 100 °C (212 °F) | 150.2 °C (302.4 °F) |

| Density | 1 g/mL | 1.45 g/mL |

| Flammability | Non-flammable | Flammable |

| Reactivity | Relatively unreactive | Strong oxidizer, highly reactive |

| Toxicity | Non-toxic | Toxic, can cause skin irritation and burns |

| Uses | Drinking, cleaning, industrial processes | Disinfectant, bleaching agent, rocket fuel |

In summary:

* H₂O is a stable, essential compound for life, while H₂O₂ is a reactive and potentially dangerous chemical.

* While they both contain hydrogen and oxygen, the different arrangement of these atoms leads to significantly different properties.
