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.

What are the particles called that carry the electric current through through the metal wires in electrolysis?

The particles that carry electric current through metal wires in electrolysis are electrons. Electrons are negatively charged particles that flow from the negative terminal of the power source to the positive terminal, creating an electrical circuit that drives the electrolysis process.


Name of the process that decomposes water?

The process that decomposes water into hydrogen and oxygen gas is called electrolysis. It involves passing an electric current through water to split it into its constituent elements.


How do you strip hydrogen from water?

To strip hydrogen from water, a process called electrolysis is used. In electrolysis, an electric current is passed through water to split it into hydrogen and oxygen gases. The hydrogen gas is collected at the cathode while the oxygen gas is collected at the anode.


How can the use of electric currents be employed to create a magnet?

Electric currents can create a magnet by running through a coil of wire, which generates a magnetic field. This process is known as electromagnetism.


Which type of chemical reaction takes place when electric current is passed through water?

The process is called electrolysis, and it usually results in a decomposition reaction. For example, passing an electric current through water results in the reaction 2H2O --> 2H2 + O2.
