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.
Biography: Antoine Lavoisier
By: D. Vogt
Antoine Lavoisier (1743-1794) was a French aristocrat, businessman, and chemist best known for his successful attack on the Renaissance theory of phlogiston and his contributions to the law of conversation of mass, the periodic table of elements (in his time, only existing in list form)...
Biography: Joseph Priestley
By: D. Vogt
Joseph Priestley (1733-1804) was a Dissenting theologian and an Enlightenment-era chemist. He is best known for his pioneering study of oxygen, although it occurred within the context of the now-rejected Renaissance theory of "phlogisticated air" which plagued European chemistry until late in his lifetime. -...

In November 2006, Alexander Litvinenko, a former KGB agent who had been granted asylum in the United Kingdom, took 3 weeks to die of radiation poisoning from polonium. Polonium’s discoverers, the Curies, would have been horrified. As Marie Curie once said, “I am...

The periodic table is one of the most well-known systems in chemistry and is used to classify the known elements. It is commonly used in chemical engineering, physics, biology and other hard sciences. Even though it is in widespread use, some confusion still exists about...

The periodic table is universally recognized in chemistry for organizing all known chemical elements. It has widespread use in chemical engineering, physics, biology and other hard sciences. Despite its common use, it can be quite confusing upon first glance. However, after the major parts are...
The combined gas law: Three gas laws in one
By: Joshua Horn - 257112
The combined gas law is the combination of three other gas laws, each of which relates two thermodynamic variables. By combining them into one equation, you can quantify the relationship between all three thermodynamics variables: pressure, temperature and volume. This is extremely useful in chemistry...
Fun home chemistry projects: Making sugar crystals
By: Joan Collins
Chemistry should be elevated to the reputation it deserves. Experiments in chemistry are be exciting and fun. Sometimes they can be downright tasty. Growing sugar crystals presents a fun way to study monoclinic crystals. This will include sharp right angles and smooth faces with a...

When it comes to science, there are tons of misconceptions that bedazzle the way we think about certain things. There are misconceptions when it comes to nutrition, when it comes to biology, when it comes to chemistry as well as when it comes to physics...
Everyday examples of mixtures
By: Asra Arshad
A mixture is when there is a combination of at least two or more substances physically combined together, not chemically. This means that the atoms of each of the substance to do not chemically bind together and can therefore be removed through simple processes. If...

Transport coefficients are mathematical constants that arise in differential equations in times and places that describe physical phenomena in the area of non-equilibrium statistical mechanics. These transport coefficients describe the behavior of the physical system when there is a deviation from equilibrium state. This deviation...
