Yes, it is a chemical change; new compounds (elements) are formed !

∙ 12y agoA chemical change is when one substance combines with another to form a new substance or when one substance decomposes into one or more substances.
since water is breaking into two separate chemical, ie hydrogen and oxygen, which are chemicals in its own right, so the answer is yes.

∙ 16y agowater is a molecule created from two types of atoms (oxygen and hydregen) connected by a strong chemical bond, if you break it you're changing the chemical water to the two atoms
Wiki User
∙ 10y agoYes it is a chemical change .Because when oxygen and hydrogen get mixed they form a new substance called water.
Wiki User
∙ 13y agoWater cannot be decomposed by a chemical change because it can only be separated by artificial means.
Wiki User
∙ 12y agoYes. It is called electrolysis, and decomposes water into oxygen gas and hydrogen gas.

Is hydrogen burning a physical or chemical change?
burning in presence or absence of oxygen is a chemical change.
Is it a chemical or physical change when a scientist break-up water into oxygen and hydrogen gas?
It would be chemical change.
Is using electricity to separate water into hydrogen and oxygen a chemical change?
physical change
Why is the electrolysis of water is classified of physical change but the freezing of water is not?
Freezing is a phase transition and does not change the chemical makeup of H2O. (melting restores). Electrolysis changes the chemical structure of the water, decomposing the H2O into oxygen (O2) and hydrogen gas (H2).
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 decomposing water physical or chemical change?
Chemical change; bonds are broken when water decomposes into hydrogen and oxygen.
Is hydrogen burning a physical or chemical change?
burning in presence or absence of oxygen is a chemical change.

Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
Is breaking water up into oxygen and a hydrogen gas a physical or chemical change?
Breaking water into the component parts of hydrogen and oxygen is a CHEMICAL change.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
What is a sentence using hydrogen oxygen chemical change compound water?
There are many sentences that could include these terms. One such sentence is the following: The process by which hydrogen and oxygen convert to water is a chemical change. Also: water is formed in a chemical change involving hydrogen and oxygen.
Is hydrogen and oxygen combing into water a chemical change?
Yes, hydrogen and oxygen combining into water is a chemical change, represented by the following equation: 2H2 + O2 ---> 2H2O
Is the element hydrogen and oxygen combine to form hydrogen peroxide a chemical change?
Yes it is.
Is hydrogen burns in chlorine gas chemical or physical change?
When you combust hydrogen in air, the hydrogen will combine with oxygen to form water. Therefore, the hydrogen and oxygen are undergoing a chemical change to become bonded together producing H2O: 2H2 + O2 → 2H2O + Heat
What are the two criteria for whether a change is chemical or physical?
Oxygen and hydrogen
Is a sugar a chemical change?
Sugar is a chemical compound or rather a group of compounds containing carbon oxygen and hydrogen, not a chemical change.
