Chemistry

Every moment of every day, chemistry plays a part in all we experience. This branch of the Helium network humbly attempts to illuminate the vast array of chemical knowledge, making it accessible to all. Let our site inform, inspire, and awe you with chemical wonders.
What happens chemically when acids and bases are mixed
By: James Johnson
What happens chemically when acids and bases are mixed? If general the two cancel each other out and you end up with salts and water! What happens chemically when you mix acids with bases? You can get strange smells and hot solutions, and some can...
Chemistry experiments for elementary school students
By: James Johnson
Science is important for understanding how the physical things in the universe work. The more we understand science, the better we will be able to use the things we have. It is also important to note that younger children learn most things quicker than we...

Benzoyl peroxide has the chemical formula C14H10O4, and can be envisioned as a pair of benzoic acid molecules, joined together at the oxygen atoms from which the acidic hydrogen atoms are missing. Benzoyl peroxide belongs to the general class of organic peroxides. Its reactive properties...
Element facts: Argon
By: D. Vogt
Argon (atomic number 18; abbreviation Ar) is a colourless, oudorless gas which is classified as one of the noble gases (also known as inert gases). It is commonly found in certain industrial activities and in certain types of electric lighting, and is also used in...
What is clinical chemistry?
By: Virginia Gaces
Clinical chemistry is defined in layman’s language as the study of the substance in biological fluids most specifically blood, the methods and principles of determination, the intrinsic and extrinsic precautions, the normal levels and the clinical significance of abnormal values. It belongs to...
Exploring the composition of air
By: D. Vogt
Air refers to the mixture of gases and water vapour which make up the atmosphere of the Earth. Note that this particular balance is specific to Earth - other planets have other atmospheres, and therefore different air. For example, the atmosphere of Mars is 95%...
Element facts: Neon
By: D. Vogt
Neon, like argon and helium, is an inert gas or noble gas: that is, it is a gas with no smell and no colour which does not react with other chemicals under normal conditions outside the laboratory. Neon's chemical symbol is "Ne," and it...
By: D. Vogt
That helium makes your voice squeaky is known to everyone who joyfully discovered this little trick while playing with helium balloons as a child. In a sense we are all, then, highly fortunate that the inert and harmless helium was discovered and manufactured in large...
What is a zeolite?
By: Frank Kero
Zeolites are complex and beautiful hydrated inorganic structures that can best be described as molecular sieves since they can selectively separate gases and liquids on the molecular level by virtue of inherent supramolecular cage structures. The principle chemistry of these structures finds practical application in...
Easy definitions of chemistry
By: D. Vogt
Chemistry, at its most basic, is the branch of science which studies the nature of, and changes in, physical matter - that is, chemicals. Whereas physics studies the composition of matter from the perspective of movement and energy, chemistry does so from the perspective of...
