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-
6

Is electroplating physical or chemical change?
Electroplating involves a combination of physical and chemical changes. The metal ions (chemical change) in the solution are reduced and deposited onto the object's surface using electricity (physical process).
Is water a physical or chemical change?
Water changing from liquid to solid (ice) or gas (steam) is a physical change, as the chemical composition of water remains the same. However, when water undergoes electrolysis to produce hydrogen and oxygen gas, it is a chemical change as the chemical composition of water is altered.
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.
How is the process of making hydrogen from water both a physical and chemical transformation?
The process of making hydrogen from water involves both physical and chemical transformations. Physically, water molecules are separated into hydrogen and oxygen through a process called electrolysis. Chemically, this separation involves breaking the bonds between hydrogen and oxygen atoms, resulting in a chemical 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).

Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
When an object does not react with hydrogen is that a chemical change or physical change?
Easy, chemical change.
Is a reacts with an acid to from hydrogen physical or chemical?
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.
Dissolution of hydrogen chloride gas in water is a physical change or chemical change?
It is a chemical change ....
