DID YOU KNOW?
The lightest gas or substance in Nature is hydrogen. It also makes up almost every thing because it makes up about 90 % of all atoms. Here on earth it is usually combined with some other element. Hydrogen combined with oxygen creates water.
Two ancient Greek words make up the name hydrogen - hydr [meaning water] and gen [origin, birth ]
Water is H₂O - Hydrogen 2 parts and Oxygen 1 part
Hydrogen must somehow become intensely heated before it combines with the oxygen contained in the air. But when this happens water is formed.
Hydrogen has the least weight of all the elements that make up matter.
Matter is simply a mass of atoms It is all the things that get formed by atoms coming together. Everything material is what you can see, touch taste smell, maybe even hear.

EXTRA FACT - Hydrogen Peroxide is H2O2, Hydrogen 2 parts and Oxygen 2 parts. The extra part oxygen is what makes it bubble and clean. When Hydrogen Peroxide gets exposed to heat or light it starts to decompose. It breaks down and separates the extra part oxygen away and leaves just water - H2O. It is this reaction that causes the germs and stuff on whatever it touches to also break down, leaving a sort of bleaching effect. After the bubbling stops only water is left to rinse the area.
Pure hydrogen peroxide is a pale blue color but the bottled product we use is diluted with water and is only a small percent of pure hydrogen peroxide.
