pass an electric current through water - H20, and the current will divide the water molecules into hydrogen gas and oxygen gas
Hydrogen itself IS an atom.
The product is hydrogen. to test for hydrogen, take a lighted match or a splint and bring it near the place where you think there is hydrogen and if you hear a squeaky "POP!" there is hydrogen there
chinese
Cesium
Hydrogen and Chlorine
It can be both.
water
Yes, hydrogen is a product of this reaction.
When hydrogen burns, the product is water. 2H2 + O2 ==> 2H2O
Hydrogen can be a reactant or a product, it depends on the chemical reaction. Anything to the left of the arrow is consumed by the reaction and is thus a reactant, so hydrogen is a reactant in the reaction O2 + 2H2 -> 2H2O. A product is on the right of the arrow and is produced by the reaction, so hydrogen is a product in the reaction Zn + 2HCl -> ZnCl2 + H2
There is only one product - water. Hydrogen burns in the oxygen in air to form hydrogen oxide or water vapour. 2H2 (g) + O2 (g) = 2H20 (g)
The reactant, because it is reacting to form the product of H2O.
