when you separate a substance from a mixture, it's a physical change... Technically, you can get it back in the mixture.
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

No. It is a physical change. All you have to do to separate the two is to evaporate the water. There is no chemical change.
No, it's a physical change because you can still separate the two from each other.
Physical because you are not changing the substance.
Physical change is preferable because it is easier than chemical method.
Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
No. It is a physical change. All you have to do to separate the two is to evaporate the water. There is no chemical change.
chemical .... :0)
A physical change, and a chemical change.
physical, because you can technically separate the milk and eggs again.
It is a physical change as an alloy is a solid solution made from various metals. As you can still separate these different metals after the alloy is made it is a physical change and not a chemical change.
