That depends on what the substances are and how they are combined or mixed. Something like ethano and water can be separated by distillation, the process taking only a few minutes, but something like a mixture of uranium-235 hexafluoride and uranium-238 hexafluoride must be split by centrifuge, the process takinf weeks to separate a small amount. Other ways of separating a mixture include melting (if it is a solid) and using density properties; dissolution, decanting and evaporation (where one or more substances are soluble in the given solute and others are not); recrystallisation (normally to remove impurities).
the way you would separate a compound would be solubility
Evaporate one of the chemicals how would i seperate the chemicals hydrogen and carbon from gasoline?
It depends on the compound. NaCl is best electolyzed molten as an example.
During a chemical change the composition of the reactants is changed.
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's a physical change because you can still separate the two from each other.
Adding salt to water is not a chemical reaction, nor is it a chemical change. When salt dissolves in water, this is an example of a physical change. Although the sodium and chlorine ions separate in the water, no chemical reaction takes place.
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.
its a chemical change because you cannot reverse the process and just have milk and vinegar separate

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

physical change
both
Whether they give off a sweet smell or not, baking is a chemical change. Can you separate the egg, the flour, the sugar? No, then it is a chemical change.
You could separate it all out.
It depends ont eh chemical change, because in some changes not all the components of the mixture are used.
A physical change, and a chemical change.
