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.

∙ 13y agoChemical change; bonds are broken when water decomposes into hydrogen and oxygen.

Yes, decomposing water into hydrogen and oxygen is a chemical change because it results in the breaking of the bonds holding the water molecules together to form new substances.

∙ 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?
The burning of hydrogen is a chemical change because it involves the rearrangement of the atoms in the hydrogen molecule to form water. This process also releases energy in the form of heat and light.
Is decomposing water by passing an electric current through it a chemical or physical change?
Decomposing water by passing an electric current through it is a chemical change because it involves the breaking of the chemical bonds in water molecules (H2O) to form hydrogen gas (H2) and oxygen gas (O2). This reaction results in the formation of new substances with different chemical properties.
Is separating water into oxygen and hydrogen an example of a change?
Yes, separating water into oxygen and hydrogen is an example of a chemical change. It involves breaking the bonds between the hydrogen and oxygen atoms in water molecules, resulting in the formation of new substances with different properties (oxygen and hydrogen gas).
Is using electricity to separate water into hydrogen and oxygen a chemical change?
Yes, using electricity to separate water into hydrogen and oxygen is a chemical change because it involves breaking the bonds between the hydrogen and oxygen atoms in water molecules to form separate hydrogen and oxygen molecules. This process is known as electrolysis.
Is mixing hydrogen and oxygen together a chemical change or a physical change?
Mixing hydrogen and oxygen to form water is a chemical change because new substances with different properties are formed. The reactants (hydrogen and oxygen) are chemically combined to create the product (water), resulting in a new chemical composition.
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?
The burning of hydrogen is a chemical change because it involves the rearrangement of the atoms in the hydrogen molecule to form water. This process also releases energy in the form of heat and light.
Why is the electrolysis water classified as a chemical 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).
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 decomposing water by passing an electric current through it a chemical or physical change?
Decomposing water by passing an electric current through it is a chemical change because it involves the breaking of the chemical bonds in water molecules (H2O) to form hydrogen gas (H2) and oxygen gas (O2). This reaction results in the formation of new substances with different chemical properties.
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 separating water into oxygen and hydrogen an example of a change?
Yes, separating water into oxygen and hydrogen is an example of a chemical change. It involves breaking the bonds between the hydrogen and oxygen atoms in water molecules, resulting in the formation of new substances with different properties (oxygen and hydrogen gas).
Is using electricity to separate water into hydrogen and oxygen a chemical change?
Yes, using electricity to separate water into hydrogen and oxygen is a chemical change because it involves breaking the bonds between the hydrogen and oxygen atoms in water molecules to form separate hydrogen and oxygen molecules. This process is known as electrolysis.
Is the element hydrogen and oxygen combine to form hydrogen peroxide a chemical change?
Yes it is.
