What happens to oxygen when hydrogen is removed from h2o?
When hydrogen is removed from H2O, oxygen atoms remain. These oxygen atoms may bond with other atoms to form new compounds or molecules, such as O2 (oxygen gas) or H2O2 (hydrogen peroxide), depending on the conditions.
Does hydrogen leave residue on burning?
Nothing is left because hydrogen is an element, from which only water is formed when burning (explosively) with oxygen.
Why is it necessary for there to be a polar covalent bond in order for a hydrogen bond to occur?
A hydrogen bond occurs when a hydrogen atom from one molecule is attracted to an atom (usually oxygen) of another molecule. There is a small positive charge on a hydrogen atoms in many covalent bonds due to H's very low electronegativity. This results from a polar covalent bond. Likewise, there is usually a small negative charge on an oxygen atom in a covalent bond due to O's relatively large electronegativity. This is also the result of a polar covalent bond. The +/- attraction that results from these polar bonds is what a hydrogen bond actually is. In the absence of a polar covalent bond, there will be no residual charge left on either the hydrogen or the oxygen and therefore no hydrogen bonding will occur!
What percentage of body mass is left if you eliminate nitrogen and oxygen?
If you mean the "pure" gases, more than 99%. If you're referring to the compounds that include N2 & O2 then only a few percent would be left.
What is left when water loses a hydrogen ion?
A hydroxide ion (OH-)hydroxide ion
What happens when hydrogen and oxygen is mixed?
water is left
What gasses are left when copper reacts with oxygen in the air?
Hydrogen
Can water be formed by mixing hydrogen and oxygen?
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.
What chemicals were the products in the reaction in producing of hydrogen and oxygen gases?
This question answers itself. The products of a reaction PRODUCING hydrogen and oxygen are, well, hydrogen and oxygen!If you are asking what hydrogen and oxygen are made FROM, than the REACTANT is water. If a voltage is applied to water, hydrogen and oxygen gas are made.If you are asking what the product of a reaction is when hydrogen and oxygen are the REACTANTS, then the answer is also water.See the Related Questions for more information to the left of this answer.

What changes when you burn a popsicle stick?
Wood is made of three basic elements: hydrogen, oxygen, and carbon. When it burns the oxygen and hydrogen combust and the carbon is left over. This is the quick and easy explanation.
If hydrogen peroxide is left outside?
It degrades into water and oxygen gas. That is why hydrogen peroxide bottles are brown, to keep light from breaking it down.

Nothing is left because hydrogen is an element, from which only water is formed when burning (explosively) with oxygen.
When hydrogen and oxygen are mixed they form water then why exist in gaseous form?
very high temperature is needed to combine hydrogen and oxygen. at that temperature, water exists in gaseous form Oxygen exists as a gas in our atmosphere, because there isn't very much hydrogen in the atmosphere. If the Earth's atmosphere contained a substantial amount of hydrogen mixed with the oxygen, it would be an explosive mixture. Any spark would set it off. They the oxygen and hydrogen would combine to form water, and we would be left without enough oxygen to breathe.
How do you know the that water is not a mixture of hydrogen and oxygen?
Since water and carbon dioxide are both compounds which contain oxygen, it is possible to obtain oxygen from either, but you get a different residue depending upon which compound is the source of the oxygen. Take the oxygen out of water and you are left with hydrogen gas; take the oxygen out of carbon dioxide and you are left with carbon, which is a black solid. It is easy to spot the difference between hydrogen and carbon.
Do carbon dioxide water and glucose hve all elements?
No. Carbon Dioxide (CO2)= 1 Carbon molecule, 2 Oxygen. Water (H2O)= 1 Oxygen, 2 Hydrogen. Glucose (C6H12O6)= 6 Carbon, 12 Hydrogen, 6 Oxygen. There are 115 left. Hope this helps.
Who first showed that water consists of hydrogen and oxygen?
John Dalton in 1803.See the Web Links to the left of this answer for more information.
