Water can be split by electrolysis to produce hydrogen and oxygen. if you do this you find you get twice as much hydrogen as oxygen and no other products. if the two gases are combined again by adding a spark, water is produced, again with no other products (apart from a loud BANG if you have a large sample :-)
What else can I help you with?
What is difference between hydrogen sulfide and hydrogen sulphide?
There is no difference between hydrogen sulfide and hydrogen sulphide. The term "sulfide" and "sulphide" both refer to the chemical compound H2S, also known as hydrogen sulfide. The difference in spelling is simply a matter of regional or historical variation.
When was heavy hydrogen discovered?
13 of November,1555 it was discovered by Mr.Robert Boyle
In a chemical formula H2O what does the 2 tell you?
The formula H2O tells you that one molecule of water contains one Oxygen atom and two Hydrogen atoms.
What is the word equation for the reaction between hydrogen and fluorine?
Hydrogen + fluorine ---> hydrogen fluoride
How many product atoms are there in hydrogen?
There is one atom of hydrogen in a hydrogen molecule.
What chemical is made when hydrogen burns?
When hydrogen burns, it combines with oxygen to form water (H2O).
How can you tell if hydrogen gas has been let off?
You can use a lit splint and hold it over where you think the hydrogen is, and if you hear a loud squeaky pop sound it will prove the existence of hydrogen there. You can also test of hydrogen using a Hydrogen Leak Detector.
Which is larger a hydrogen atom francium or atom and how can you tell?
The francium atom is larger.
What is difference between hydrogen sulfide and hydrogen sulphide?

What does every element in the first period have?
i dont know i was waiting for u to tell me.....
How can you tell there is more oxygen in hydrogen peroxide than in water?
You can tell that there is more oxygen in hydrogen peroxide than in water because hydrogen peroxide has an extra oxygen atom compared to water. The chemical formula for hydrogen peroxide is H2O2, while the formula for water is H2O. This extra oxygen in hydrogen peroxide makes it a more oxidizing chemical compared to water.
How can you tell glucose is organic?
The formula for glucose is C6H12O6. The carbon and hydrogen indicate that it is an organic compound.
What can you tell about the makeup of water from its symbol?
its made of two hydrogen atoms and one oxygen. obviously.
What is some interesting things about hydrogen?
Well, it's not an atom I'll tell ya that much!! BYE!!
How can you tell the difference between helium and hydrogen gas?
The easiest way to distinguish them is by the combustion test. Hydrogen is flammable and will burn. You can also pass hydrogen, which is reactive, through various solutions and it will be combined, whereas helium will almost never chemically react.
Density of Hydrogen?
Gaseous hydrogen has a density of 0.08988 g/cm. Liquid and solid hydrogen have a density of about 0.07 g/ccAt standard temperature and pressure (stp), hydrogen as a gas has density 0.08988 grams per litre. Hydrogen atoms have atomic mass of 1, and diatomic hydrogen molecules have molecular mass of 2. From this we can tell that hydrogen is the lightest (least dense) element in the periodic table.
Is potassium hydrogen the same as potassium hydride?
It's impossible to tell. "Potassium hydrogen" is clearly an error of some kind; it might be a somewhat confused attempt to write "potassium hydride," or it could be an omission error for something like "potassium hydrogen carbonate."
