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.
Tips for making candy glass
By: Sandra Louis
Candy glass is easy and fun to make. The project involves chemistry and cooking, a win-win combination. As the sugar is heated with the other ingredients, the sugar’s chemical structure changes and it binds to the other materials. Heat becomes an important catalyst in...
Factors that affect vapor pressure
By: Ernest Capraro
The molecules (and atoms) of liquids and solids are constantly in motion. When they have enough energy, they may, upon reaching the surface, escape into the surrounding environment as a gas. Vapor pressure refers to the partial pressure of this gas at equilibrium. That is...

In movies, you see a fight such as a barroom brawl. Someone hurls another person through a glass window or door. You hear a spectacular crashing sound but the person gets away unhurt except for some fake blood. The jagged pieces of glass look real...

Borax snowflakes are an excellent project to welcome the new year and the snowy month of January.Students will enjoy making the Borax snowflakes. They can be used to create and beautiful blizzard in the classroom.A crystal is a solid with flat sides. It...
How to safely create an endothermic reaction
By: Sandra Louis
Do you care if a chemical reaction is endothermic? Do you like ice cream? Without an endothermic reaction, ice cream would just be soup. First, what is an endothermic reaction? Glad you asked. An endothermic reaction is a chemical reaction that requires energy. Simply put...

An iconic classic, the potato battery has been found in classrooms, in kitchens, and yes - even on the 80’s television series “MacGyver”. From a nutritional standpoint, the potato is sometimes hailed as a miracle food. Is there something special about potatoes that...

There are hazards associated with any chemical reaction, though some receive more attention than others. Danger is clearly associated with fires and explosions, which are produced by exothermic reactions that can release tremendous amounts of energy. Still, even endothermic reactions, which take in energy, have...
An overview of the new chemical element Copernicium
By: D. Vogt
Copernicium (Cn), previously known as ununbium (Uub), is a chemical element with atomic number 112 (making it one of the highest-numbered and heaviest elements known to exist). Thus far, less than a hundred atoms of copernicium have ever been confirmed to exist following creation in...

There are two main risks associated with using kitchen glassware for chemistry experiments. The first centers on the type of glass itself, and whether it is appropriate for the experiment. The second deals with the potential for cross-contamination between food and chemistry uses. As with...
