Oxygen began entering Earth's oceans around 2.32 billion years ago, and shallow seas followed within a few million years.

The aim of the book “Oxygen atom transfer reactions” is to outline some recent developments in the studies of oxygen atom transfer mechanisms in catalytic oxidation reactions based on several ...

In what's described as a key advancement for the development of systems to help propel humans into deep space, scientists have demonstrated a method of extracting oxygen from water in microgravity ...

Nearly 4,000 m beneath the Pacific, in water so dark that sunlight has never penetrated, scientists have stumbled on a new ...

Chemists, when they are designing or building new molecules, can be thought of as architects and builders. An organic chemist can plan a blueprint for a new molecule, and synthesize it with precision ...

To make oxygen in the laboratory the same apparatus that was used for the preparation of hydrogen is used. Hydrogen peroxide is poured into a conical flask containing some solid manganese(IV) oxide.

Oxygen is a non-metal element that is a gas at room temperature. Its molecules contain two oxygen atoms. Oxygen is vital for respiration, which is the process that transforms energy from glucose to ...
