If you mix hydrogen and oxygen then set the mixture on fire, you'll get water.

The ratio is 2 parts hydrogen atoms to one part oxygen atoms--or really one H2 molecule plus one oxygen atom because that's how hydrogen comes from the welding store you bought it from. If there's too much hydrogen you'll have some left over; too much oxygen and you'll have some of it left over.

Where do you mix hydrogen and oxygen to make water?

Water can not be produced by mixing these to gases, when hydrogen gas is burn in oxygen atmosphere the vapours of water are produced.


Is mixing hydrogen and oxygen together a chemical change or a physical change?

Just the mixing of hydrogen and oxygen isn't a change at all. But if they react under specific conditions, you have a chemical change. The reaction might look like this ... 2H2(g) + O2(g) --> 2H2O


When oxygen combines with hydrogen what substance is form?

When oxygen combines with hydrogen, water (H2O) is formed.


Is water a compound formed by sharing nitrogen?

No, water is a compound formed by sharing oxygen atoms, not nitrogen. Water (H2O) is composed of two hydrogen atoms and one oxygen atom, with the oxygen atom sharing electrons with the hydrogen atoms to form covalent bonds.


If oxygen reacts with hydrogen what do you get?

Water , however if there is insufficient oxygen some hydrogen peroxide is formed, (H2O2 )


What is the formula for the water this is formed by the oxygen and hydrogen?

There are two hydrogen atoms for every oxygen. The formula is H2O.


Why is water formed when you mix hydrogen and oxygen gases?

Water is H2O. 2 hydrogen atoms and 1 oxygen atom. Water is not formed when you mix hydrogen and oxygen. An explosive mixture of hydrogen and oxygen is formed. When you burn hydrogen in oxygen, the resulting compound is water. When you boil water the result is steam, or water vapor. Boiling does NOT separate the hydrogen and oxygen. An electrical current is needed to separate the hydrogen and oxygen. CAUTION: Do NOT put salt in the water to speed up the electrolysis of water. It changes the products. instead of hydrogen and oxygen, you get hydrogen, chlorine (gas), and sodium hydroxide. The last two are very poisonous.


What is broken down and formed in the decomposition of water?

In the decomposition of water, water molecules are broken down into oxygen gas and hydrogen gas through a process called electrolysis. This requires passing an electric current through water to separate the hydrogen and oxygen atoms.


How do you make and create water?

by mixing 2 elements of hydrogen and oxygen. (H2O) this is the recipe for water.


Is a water molecule formed from 1 oxygen atom and 1 hydrogen atom?

No. The molecule for water is H2O, meaning each water molecule contains 2 hydrogen atoms and 1 oxygen atom.


What is produced when hydrogen and oxygen react?

Hydrogen and oxygen undergo combination reaction to form water.When hydrogen and oxygen react together, water is formed.


What molecule is oxidized and what kind of bond is formed when gaseous hydrogen burns in the presence of oxygen to form water?

In this reaction, hydrogen (H2) is oxidized to form water (H2O), and a covalent bond is formed between hydrogen and oxygen atoms in water.
