Justify why electrolysis of water is a chemical irreversible change?
A chemical change is always irreversible; that's part of the definition of "chemical change". This is because a new substances with new properties are formed. In this example, hydrogen and oxygen gas.
What is water electrolysis the chemical separation of?
Hydrogen & Oxygen.
Is corrode a chemical change?
When a metal corrodes, it reacts with a chemical in the environment to produce a new substance. Often the metal reacts with oxygen to form a metal oxide. A well-known example is iron reacting with oxygen to form iron oxide, known as rust.
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.
Can a chemical reaction occur during the electrolysis of water?
yes. hydrogen and oxygen gas will be evolved
Is a silver teapot turning black a chemical or physical change?
It is a chemical change but it can be reversed since that cahnge is only on the surface. It is merely an oxidization that occurs when silver is exposed to oxygen and has no contact with oil (which blocks the pores of the metal from reacting with oxygen).
Is electroplating physical or chemical change?
Chemical because it breaks apart the individual compounds on the molecular scale.
What chemical changes does water undergo?
Electrolysis will turn water into hydrogen and oxygen gas.
Is rusting of an iron hammer a chemical change and why?
yes because oxygen is reacting with iron
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 a rusting bicycle a chemica or physical change?
Chemical - It's the iron atoms reacting with the oxygen atoms in the air. For future reference, a chemical change is irreversible, whereas a physical change can be reversed, usually quite easily.
Is reacting with oxygen a physical property of hydrogen?
Reactivity is a chemical property.
Is the formula of oxide a chemical or physical property?
Reacting with oxygen to form an oxide is a chemical property.
