Is using a fuel cell to separate water into hydrogen and oxygen a physical or chemical separation?

It's a physical change. The atoms of Oxygen and Hydrogen that made up the water molecules have simply been separated from each other.

Is using electricity to separate water into hydrogen and oxygen a chemical change?
physical change
Is water a chemical or physical separation?
Physical Separationreversible - can be separated by physical means - E.g shaking a bottle of Greek salad dressing, the different ingredients mix but don't form a new substance.Chemical Separationirreversible - can be separated by chemical means - E.g burning of wood or coal
Is separate sand from grave a physical or chemical change?
Physical because you are not changing the substance.
What is the separation of mixtures based on?
The physical properties of the things in the mixture. It could be that one part of the mixture is soluble, the other part insoluble - both physical properties. It could be that you use the boiling point of 2 liquids to separate them - physical properties. You could use a magnet if one part is magnetic and the other isn't - physical properties. And so on. But you are relying on physical properties rather than chemical properties.
If milk and vinegar is mixed is it a physical or chemical change?
its a chemical change because you cannot reverse the process and just have milk and vinegar separate

Is chemical a method used to separate mixtures?
Separation of mixtures is generally based on physical properties.

How do you separate Hydrogen and Oxygen from HHO hydroxygen or Brown gas?
The method of separation is electrolysis.
Can isotopes be separated by chemical methods?
Since isotopes are nearly chemically identical, the use of chemical processes to separate isotopes is impractical, but it is used to separate deuterium from normal hydrogen. The extreme mass differences of deuterium and hydrogen (being twice its mass), allows for a more noticeable chemical difference: when chemical equilibrium is established with water (H2O or HDO, with one deuterium replacing the hydrogen) with pure light hydrogen gas, there is 3 to 4 times more deuterium in the liquid compound than in the gas. Thus, this difference can be used to separate the heavier deuterium from light hydrogen. But the use of chemical methods would only work if the mass of the isotopes are immensely different, which only occurs with lighter elements. To separate other isotopes, the physical properties of the compounds are used since they directly relate with the slight difference in masses. The most common example of separation by physical properties is the separation by effusion, which is commonly used to separate uranium-235 (used in weapons and power generation) and uranium-238. These mass differences result in a different effusion rate as predicted by the Kinetic Molecular Theory, thus the lighter U-235 effuses faster than U-238, and the process being repeated many times nearly pure U-235 results.
Is separate is a physical or chemical change?
when you separate a substance from a mixture, it's a physical change... Technically, you can get it back in the mixture.
What is used to determine which separating technique is to be used to separate a particular mixture?
- the physical nature of the components- the chemical nature of the components- the amount of the mixture- the availability of necessary devices and materials for separation- the price of componentsetc.
Is separate sand from grave a physical or chemical change?
Physical because you are not changing the substance.
Are physical and chemical change different?
Physical change does not produce a new substance. Chemical change produces a new substanceIn a chemical change the atoms/molecules are chemically joined together so they are very hard to separate. were as they are easyer to separate in a physical change
What physical separation would allow to separate a mixture of muddy water?
It is possible to filter mud out of water.
What is the base word of separation?
The base word of separation is "separate."
