From a chemist's perspective, organic molecules are best viewed as largely carbon-based entities equipped with functional groups that contain heteroatoms such as nitrogen, oxygen, halogens, sulfur ...

The molecular sizes of oxygen, nitrogen, and argon are 0.299, 0.305, and 0. ... This selectivity sensitively depends on the structure and property of a gas molecule and the geometry (size and ...

Using nothing but water and said olive oil, he managed to calculate the size of a single olive oil molecule as being 1.63 nanometers in length. To achieve this feat, he took 0.81 mg of olive oil ...

Gases are not separated by weight. It's true that carbon dioxide has a higher molecular weight than oxygen and nitrogen, said Suzanne Paulson, a professor of atmospheric and oceanic science at the ...

Save guides, add subjects and pick up where you left off with your BBC account. Big question. Grit, determination, hardworking, handsome, charming, funny. Teacher: Well, I guess. But you're ...

In some subterranean aquifers, cells have a chemical trick for making oxygen. It offers new insight into how life survives deep underground on Earth—and where it might lurk in space.

This increases the ratio of oxygen to nitrogen, above what’s in air. If you breathe this gas at a depth of 20 meters, which is 3 ATM, the oxygen would be at PPO 2 of 0.4 × 3 ATM, which equals 1 ...

Nitrogen-filled tires offer benefits like stable pressure, reduced moisture, and less corrosion. But regular tire maintenance is key, no matter what’s inside.

Scientists previously knew tiny amounts of oxygen lofted in Venus' night-side and, last November, a different team of researchers detected the molecule on the planet's day-side too.

Maintaining optimal levels of nitric oxide in your body is essential for your overall health. This article reviews the top 5 ways to increase your nitric oxide production naturally.

Nitrogen oxides form when oxygen and nitrogen from the air interact during a high-temperature combustion event. These conditions occur in car engines and fossil fuel-powered electricity plants.
