Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water cannot be separated into hydrogen and oxygen by boiling. Boiling is a physical change which means the molecule doesn't change at all--liquid water and water vapor are both H2O. Water can be separated into hydrogen and oxygen using electricity, this would be a chemical change.
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.
Is burning of hydrogen in air chemical change?
yes it is a chemical change.
Is hydrogen burning a physical or chemical change?
burning in presence or absence of oxygen is a chemical change.
Is does not react with hydrogen a physical or chemical change?
Chemical
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.

yes it is a chemical change.
Is breakdown of matter by electricity chemical or physical change?

Is hydrogen burning a physical or chemical change?
burning in presence or absence of oxygen is a chemical change.
When an object does not react with hydrogen is that a chemical change or physical change?
Easy, 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.
Why is water change to hydrogen peroxide a chemical change?
Water - H2O; Hydrogen peroxide - H2O2. It is a change of chemical formula , it is another type of molecule.
