Is separating water into oxygen and hydrogen an example of a change?

The breaking up of water molecules by separating it into hydrogen and oxygen is an example of chemical change. This is because a chemical change is one where atoms and bonds rearrange to form new molecules.

∙ 13y agoYes, it is a chemical change because it changes the chemical property and water is a different substance now. It is not H2O anymore. It is a new substance.
Wiki User
∙ 13y agoNo it is an heat transfer because it was chemical but since its burning its thermal (heat) :) ur welcome
Wiki User
∙ 8y agoYes, this is definitely a chemical change, absolutely not a physical.
Wiki User
∙ 14y agoNo the process of separating water in to hydrogen and oxygen is a chemical change called hydrolysis.

What is an example of a chemical change that took a long time to occur?
The reaction of hydrogen and oxygen at room temperature.
Are hydrogen and oxygen a change of state?
If water is being split into hydrogen and oxygen then a change of state (phase change) will occur if the water is in liquid form and the hydrogen and oxygen are evolved as gases. If water vapor is being split, then obviously no change of state occurs. Conversely, solid water in the form of ice could be split into hydrogen and oxygen gas, also undergoing a phase change.
What chemical changes does water undergo?
Electrolysis will turn water into hydrogen and oxygen gas.
Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water cannot be separated into hydrogen and oxygen by boiling. Boiling is a physical change which means the molecule doesn't change at all--liquid water and water vapor are both H2O. Water can be separated into hydrogen and oxygen using electricity, this would be a chemical change.
Is using electricity to separate water into hydrogen and oxygen a chemical change?
physical change
Separating water into oxygen and hydrogen is an example of?
elements and compounds?
Separating water into hydrogen gas and oxygen gas requires electricity this reaction is an example of an?
ignition
Is hydrogen and oxygen combining to form water and example of a physical change?
No, it is not.
Can hydrogen be collected out of water by separating it from oxygen using fish gills?
no
What is one example of a chemical change?
Burning hydrogen (hydrogen + oxygen -> water: 2H2 + O2 => 2H2O)
One example of chemical change is what?
Burning hydrogen (hydrogen + oxygen -> water: 2H2 + O2 => 2H2O)
Can oxygen and hydrogen be mixed after separating them from air?
No one obtains hydrogen by separating it from air. There's not enough hydrogen present in air for that to be a viable source. However, it's possible to mix oxygen and hydrogen, yes. It forms a flammable (and explosive, if you get the proportions just right) mixture of gases.
Catalist for separating hydrogen from water?
Catalysts speed a reaction that would naturally happen. Water does not spontaneously decompose into hydrogen and oxygen - it needs energy input to split. There is no catalyst that can change these facts.
Example of physical change and a chemical change?
when water changes to water vapour by heating is an example of physical change. when water is divided into oxygen and hydrogen by passing electricity is an example of chemical change.
What is the difference of water molecules separating and breaking apart?
Water molecules separating means they are spreading, or in other words, the water is evaporating. When they are breaking apart, the hydrogen and oxygen are separating.
What is an example of a chemical change that took a long time to occur?
The reaction of hydrogen and oxygen at room temperature.
Does platinum change water back to hydrogen and oxygen?
Does platinum change water back to hydrogen and oxygen using a current
