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.

Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water can be separated into hydrogen and oxygen through a chemical change called electrolysis, which uses an electric current to break apart the water molecules. Boiling water is a physical change that only changes the state of the water from liquid to gas, but it does not separate the water into its component elements.
Is using hydrogen as a fuel in cars a chemical change?
To get Hydrogen as a fuel to be used in electric vehicles, the hydrogen combines with oxygen giving of 2 electrons which powers the application. The waste product is H20 (water!). If you want a simple yes or no, then the answer is Yes, because you are converting Hydrogen into Water to produce electricity.
Why is separating water into oxygen and hydrogen chemical change?
Separating water into oxygen and hydrogen is a chemical change because it involves breaking the chemical bonds within the water molecule and forming new bonds to create the two separate elements. This process requires a reaction to occur, resulting in a chemical transformation.
Is using a fuel cell to separate water into hydrogen and oxygen a physical or chemical separation?
Using a fuel cell to separate water into hydrogen and oxygen is a chemical separation process. It involves the electrolysis of water, which is a chemical reaction that breaks down water molecules into hydrogen and oxygen gases.
Is hydrogen burning a physical or chemical change?
The burning of hydrogen is a chemical change because it involves the rearrangement of the atoms in the hydrogen molecule to form water. This process also releases energy in the form of heat and light.
What would cause a chemical change water?
Adding electric current to separate hydrogen from oxyge.
Example of physical change and a chemical change?
when water changes to water vapour by heating is an example of physical change. when water is divided into oxygen and hydrogen by passing electricity is an example of chemical change.

Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.

Is breakdown of matter by electricity chemical or physical change?
chemical change
How do you separate hydrogen from water using the sun?
Firstly, we tend not to use the word 'separate' when talking about a chemical change such as this. You have to decompose the water into hydrogen and oxygen. The easiest way to do this is to pass electricity through the water, a process called electrolysis. There are two ways to make electricity from the Sun's energy. The first is to use a photovoltaic cell, which converts light to electricity. You can also use the Sun's heat to boil water, to make steam, which can drive a conventional electrical generator. This produces alternating current, so you would also need an inverter.
