Is oxidizing a physical or chemical change?

Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.

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.

Justify why electrolysis of water is a chemical irreversible change?

Electrolysis of water involves the decomposition of water molecules into hydrogen and oxygen gases through the passage of an electric current. This results in a chemical reaction that cannot be easily reversed by simply recombining the hydrogen and oxygen gases back into water. The process requires energy input and irreversible transformation of the water molecules into different chemical substances.

Is metal rusting a physical change in matter?

Yes, metal rusting is a chemical change in matter. It involves the metal reacting with oxygen in the presence of moisture to form a new compound (rust), which changes the chemical composition of the metal.

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 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 oxidizing a physical or chemical change?

What is a reacts with oxygen is it physical or chemical?

When a substance reacts with oxygen to form a new substance, it is a chemical reaction. This type of reaction is known as oxidation.

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 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.

What is the chemical equation of oxygen reacting with hydrogen to yield water?

The chemical equation for the reaction of oxygen reacting with hydrogen to yield water is 2H2 + O2 → 2H2O.

What chemical reaction produces hydrogen?

Water electrolysis is a chemical reaction that produces hydrogen gas. In this reaction, water (H2O) is split into hydrogen gas (H2) and oxygen gas (O2) using an electric current.

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 reacting with oxygen a physical property of hydrogen?

No, reacting with oxygen is a chemical property, not a physical property, of hydrogen. Physical properties are characteristics that can be observed without changing the substance's chemical composition, such as density or color. Chemical properties, on the other hand, describe how a substance can change or react to form new substances.
