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.
Examples of Charles Law
By: Cyrus Irani
Charles law states that if the volume of a gas is kept constant, the pressure of the gas is directly proportional to the temperature. Which suggests that in an ideal situation where the volume does not change, if either the pressure or temperature is increased...

Phlogiston does not exist and never did. However, during much of the 17th and 18th centuries many scientists and philosophers believed that it did, and that it solved the age-old problem of explaining what happened when things burned. Robert Boyle (1627-91) had discovered that fire...
The specific gravity of helium
By: Cathy Wieder
The Specific Gravity (SG) of Helium is 0.138 at normal temperature and pressure (NTP). Helium is slightly more than 7 times lighter than air, which is why helium filled balloons rise into the atmosphere and float away. -Characteristics of Helium- Helium, which is abbreviated...

Batteries are an electrochemical system that generates an electrical current by taking advantage of the electron movement between different metals submersed in a conductive liquid. This net flow of electrons provides power to electronics. They are critical to our modern, technology driven society. There are...

Here’s a fun science experiment to try that’s sure to raise a few eyebrows. Making your own bio-polymer, or “bio-plastic,” from household items. It’s a biodegradable idea that’s starting to become popular as both a hobby and a serious...
Fun ways to explain atoms and matter for kids
By: Marilyn Martin
The easiest way to explain atoms, molecules and matter to kids, is with visual displays or games. Just reading a book or seeing things on a chalkboard, will not impress the average student. Nor will it inspire them to read further, let alone consider a...

Chemistry science fair projects: Making pH neutral soaps Learning how to make pH neutral soap is an excellent, and moderately easy, project to choose for a Chemistry Science Fair Project. Before we actually delve into the process of how to actually make soap pH...

Iron is one of the most useful metals that exist on earth. Because of its physical properties, like strength and high melting point, it is used to make several industrial machines and everyday commodities. Examples include bridges, iron sheets for roofs of houses, doors and...
How understanding chemistry can help you in daily life
By: Kevin J. Browne
I remember as a kid being very bored in chemistry class. A few experiments here and there and a mountain of equations somehow could not compel me to curiosity for molecules and chemical reactions. How unfortunate. The worst part is that my boredom was almost...

A reaction rate is simply the speed at which a reaction occurs. Chemical kinetics, the study of reaction rates, analyzes the five main factors that influence the rate of a chemical reaction: temperature, concentration, particle size, the nature of the reaction, and the presence of...
