The combustion of hydrogen produces water:
2H2 + O2 = 2H2O
when 2 molecules of hydrogen gas and one molecule of oxygen react with each other then they form water(H2O)
When hydrogen burns, water is formed.
The gas formed when hydrogen atoms fuse is helium. Stars do this.
Water 2H2+O2 --> 2H2O
Hydrogen Chloride
The reaction produces hydrogen gas as will most reaction between an acid and a metal.
When water splits, hydrogen gas and oxygen gas are formed.
Decompose water with electrolysis, hydrogen gas and oxygen gas is formed. React water with sodium metal, hydrogen gas is formed. React magnesium metal with any acid, hydrogen gas is formed. React hydrochloric acid with calcium carbonate, carbon dioxide gas is formed.
by doing something.....
hydrogen gas
hydrogen gas
H plus H is H2.Hydrogen gas is formed.
