Is electrolysis of water to form hydrogen and oxygen a physical or chemical change?

It is a chemical change because you are breaking the water into its elements, hydrogen and oxygen, and it is no longer water.
I NEED THE NUMBER'S
^ Here They are
Oxidation of ions or neutral molecules occurs at the anode, and the reduction of ions or neutral molecules occurs at the cathode. For example, it is possible to oxidize ferrous ions to ferric ions at the anode:Fe2+
aq → Fe3+
aq + e-
It is also possible to reduce ferricyanide ions to ferrocyanide ions at the cathode:Fe(CN)3-
6 + e- → Fe(CN)4-

Are the changes produced by electrolysis chemical or physical in nature?
The changes produced by electrolysis are chemical.
Is electrolysis of NaCl a chemical change or not?
Electrolysis is a chemical change.

Chemical
Is decomposition a physical or chemical property?
Decomposition is the process of a compound breaking up into the elements it was comprised of. For example, in electrolysis water decomposes to create hydrogen and oxygen. Because the chemical bonds holding the hydrogen and oxygen molecules were broken, decomposition is a chemical change.

Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
When an electric currents is passed through water during the process of electrolysis?
It is a chemical change which manifests a physical effect of gas being evolved from a liquid. If the gases already existed and were just coming out of solution, it would be a physical change, but since it is a change from water molecules to oxygen and hydrogen molecules it is definitely a chemical change, not a physical one.
When an object does not react with hydrogen is that a chemical change or physical change?
Easy, chemical change.
