Students investigate the polarity of the water molecule and design tests to compare water to less polar liquids for evaporation rate, surface tension, and ability to dissolve certain substances.

Water and the bad smelling molecule hydrogen sulfide do not seem to have a lot in common at first sight. However, when ...

How does water form at the molecular level? Water forms when one oxygen atom bonds with two hydrogen atoms. This chemical bond creates a water molecule, symbolized as H₂O. Hydrogen and oxygen atoms ...

TL;DR: Researchers from Northwestern University have observed the formation of a water molecule on the nanoscale for the first time. Using palladium to catalyze the reaction, they witnessed ...

We all know the ingredients for water. You take two atoms of hydrogen and one of oxygen, moosh them together just so, and ...

The dot and cross diagram shows that a water molecule is made up of one oxygen atom joined to two hydrogen atoms, so the formula of water is H 2 O. A nitrogen molecule is made up of two nitrogen ...

Sparkling water has a slightly acidic pH. Over time, drinking a lot of it may contribute to the erosion of tooth enamel, says ...

The country's water resources are massively contaminated by a molecule produced by the degradation of flufenacet, a pesticide ...

The molecule, called pyrene, is made up of four fused planar rings of carbon. It's therefore categorized as a polycyclic aromatic hydrocarbon (PAH) — one of the most abundant complex molecules ...

News reports of so-called forever chemicals in drinking water have left people worried about the safety of tap and bottled ...

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 ...
