Product Description
O2 refers to molecular oxygen, which is a diatomic molecule consisting of two oxygen atoms bonded together. Here are some key points about O2:
- Chemical Formula: O2
- Molecular Weight: 32.00 g/mol
- Structure: O2 has a linear molecular geometry, where the two oxygen atoms are bonded by a double bond. The molecule is relatively stable due to the presence of a double bond.
- Physical Properties: Molecular oxygen is a colorless, odorless, and tasteless gas at room temperature and atmospheric pressure. It has a boiling point of -183.0°C (-297.4°F) and a melting point of -218.8°C (-361.8°F).
- Abundance: Oxygen is the third most abundant element in the universe and the most abundant element in the Earth's crust. It constitutes approximately 21% of the Earth's atmosphere.
- Reactivity: O2 is highly reactive and readily participates in various chemical reactions. It supports combustion, allowing substances to burn in the presence of oxygen. Many biological processes, including respiration, rely on the utilization of oxygen.
- Importance: Molecular oxygen is crucial for sustaining life on Earth. It is essential for aerobic respiration, the process by which organisms convert nutrients into energy. O2 is also involved in various chemical and industrial processes, such as steel production, combustion engines, and the synthesis of various chemicals.
- Ozone: O3 is a form of oxygen that consists of three oxygen atoms instead of two. Ozone is an unstable gas formed by the reaction of O2 with ultraviolet (UV) radiation. It plays a vital role in the ozone layer of the Earth's atmosphere, where it helps protect the planet from harmful UV rays.
