What happens to oxygen when hydrogen is removed from h2o?
The oxygen atoms left behind from the water molecules join into diatomic oxygen molecules.
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.
What does balance the equation mean?
In terms of Chemistry it means to make sure that there are equal numbers of atoms on both sides of the equation. For example, H2O2 +O2 = OH + O2 is not balanced as there are only four atoms of oxygen and two atoms of hydrogen on the left, and there are 3 atoms of oxygen and an atom of hydrogen on the right. To balance it, you make it so that it looks like this: H2O2 + O2 = 2OH + O2. Now, you have 2 atoms of hydrogen on the left with four atoms of oxygen, and 2 atoms of hydrogen on the right with four atoms of oxygen. Here is another balanced equation: 6 CO2 + 12 H2O + energy → C6H12O6 + 6 O2 + 6 H2O Carbon dioxide and water plus energy yields sugar, oxygen, and water. This essential chemical reaction is known as photosynthesis.
Carbon and other nonmetals are found in which area of the periodic table?
they are usually found in the top right area of the table (carbon, nitrogen, oxygen, phosphorus, sulfur, selenium) and hydrogen in the very top left
Is potassium hydroxide flammable?
Nope, the formula of potassium hydroxide is K-O-H oxygen can combine with exactly two elements normally. K (potassium) can combine with one the same for hydrogen. There is no more reacting with oxygen left to do, so it will not burn in air. It is corrosive though, it will eat metals, and flesh, and it will also release hydrogen gas when combined with aluminum and water. Hydrogen gas is flammable.
What happens when hydrogen and oxygen is mixed?
water is left
What gasses are left when copper reacts with oxygen in the air?
Hydrogen
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.
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 happens to oxygen when hydrogen is removed from h2o?
The oxygen atoms left behind from the water molecules join into diatomic oxygen molecules.
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.
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.
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.
