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

The film discusses the evolution of chemistry from alchemy, highlighting key figures like Joseph Priestley and Antoine Lavoisier. It explains significant experiments that led to the discovery of ...

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 ...

ETH chemists have developed a tiny, high-performance oxygen sensor that fulfils a wide range of performance criteria. The main innovation is that the sensor works in a similar way to the light ...

Antoine-Laurent de Lavoisier, the French scientist, is known as the Father of Chemistry (Specifically, the Father of Modern ...

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 ...

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.
