Sodium and chlorine react vigorously when heated, giving an orange flame and clouds of white sodium chloride.

Another reason is that these long skinny molecules are loosely packed together. Polyvinyl chloride is made up of carbon, hydrogen, and chlorine atoms. If you compare polyvinyl chloride to polyethylene ...

When you pour in a salt water mixture it passes through the energized plates and a chemical reaction splits the sodium from the chlorine. A twelve volt power source is necessary for this to work.

or chlorine dioxide may serve as oxidants. Most fuel cells in use today, however, use hydrogen and oxygen as the chemicals. In the future, fuel cells could power our cars, with hydrogen replacing ...

Hydrogen gas is also produced. With very reactive metals such as potassium, the energy of the reaction causes the hydrogen to burn as the reaction takes place.

as catalysts (substances that speed up a chemical reaction without being consumed in the process), making the hydrogen more expensive. The search is on for cheaper catalysts. Researchers are onto ...
