What else can I help you with?
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.
Physical changes of oil and water?
Oil and water do not mix because they have different polarities. When oil and water are mixed, they separate into distinct layers due to their different densities. This separation is a physical change where the molecules of each substance retain their original properties.
The distillation of sea water is it physical or chemical change?
The distillation of seawater is a physical change because it involves the separation of water molecules from salt and other impurities in the seawater using heat to evaporate the water and then condense it back into liquid form. The chemical composition of the water remains the same throughout the process.
How is the process of making hydrogen from water both a physical and chemical transformation?
The process of making hydrogen from water involves both physical and chemical transformations. Physically, water molecules are separated into hydrogen and oxygen through a process called electrolysis. Chemically, this separation involves breaking the bonds between hydrogen and oxygen atoms, resulting in a chemical change.
Is mixing oil and water a chemical change?
Oil floating on water is not a "change", so asking whether it's a physical change or a chemical one is nonsense. To the extent there's any meaning at all to the question, it's a phenomenon caused by the physical properties of the two materials.
Is separation of water and gasoline a physical change?
No, it is a physical change. The water and gasoline retain their chemical and physical properties.
Is dissolving in water physical or chemical?
Dissolving in water is a physical change because it only involves the separation of molecules within a substance without changing their chemical composition.
Is the separation of a mixture a chemical or a physical change?
physical change
Is water desalination a physical change?
Yes, water desalination is a physical change. It involves the separation of salt and other impurities from water using physical processes such as evaporation or reverse osmosis, without altering the chemical composition of water.

The chemical composition of the water remains the same throughout the process.
Why is salt water a physical separation?
Salt water is a physical separation because the salt dissolves in the water, creating a homogeneous mixture. The salt molecules do not chemically combine with the water molecules and can be separated through physical means, such as evaporation or filtration.
What compound can separated by explosion?
None, explosion is chemical, separation is physical.
Does distillation produce a chemical Change or a physical Chang in petroleum?
it is a physical change
What is water electrolysis the chemical separation of?
Hydrogen & Oxygen.
