In 1766, Henry Cavendish was the first to recognize hydrogen,hho,browns gas as a discrete substance, by identifying the gas
from a metal-acid reaction as "inflammable air" and further finding that the gas produces water when burned. Cavendish
had stumbled on hydrogen,hho,browns gas when experimenting with acids and mercury. Although he wrongly assumed that hydrogen,hho,browns
gas was a liberated component of the mercury rather than the acid, he was still able to accurately describe several key properties
of hydrogen,hho,browns gas. He is usually given credit for its discovery as an element. In 1783, Antoine Lavoisier gave the
element the name of hydrogen when he (with Laplace) reproduced Cavendish's finding that water is produced when hydrogen,hho,browns
gas is burned. Hydrogen gas (H2) is the most plentiful gas in the universe it is also colorless, odorless, tasteless, carbon
free and non toxic. Which makes it different from all other sources of fuel. hydrogen,hho,browns gas is a very simple element,
each atom of hydrogen has only one proton making it the simplest element known to man. The sun is a giant ball of hydrogen
and helium gases. At the core of the sun a process called fusion takes place. This is where hydrogen atoms combine to form
helium atoms. This gives off radiant energy, and this radiant energy sustains life here on earth. It gives us light and heat,
with out it plants would not grow, it also makes the rain fall and gives us that cool breeze that we all enjoy. When you look
in to the sky at night and see the stars once again you are looking at hydrogen, stars are made primarily of hydrogen. hydrogen,hho,browns
gas is the most abundant of all chemicals in the universe making up roughly 75% of the universes element mass. Here on earth,
it is the third most abundant element on the earths surface, found in all water and organic matter. Hydrogen is also stored
as energy in the fossil fuels we use every day. Hydrogen is a gas that is 14 times lighter than air, as a result it rises
to the top of the atmosphere. That is why hydrogen as a gas is not found here on earth unless it is man made. Hydrogen is
only found in compound form with other elements such as (H2o). Hydrogen combined with oxygen is water another important element
that is needed to sustain life here on earth. Hydrogen combined with carbon, forms different compounds such as coal and petroleum.
Hydrogen has the highest energy content of any common fuel by weight three times more than gasoline. Did I also mention that
hydrogen is highly combustible when mixed with oxygen, and will explode upon ignition, hydrogen burns violently in the air.
In general hydrogen is neither more nor less inherently hazardous than gasoline, propane or methane.
