A mixture is a combination of two or more subtances.Subtances in a mixture can be separated.This means that they are chemically combined.I would prefer physical change cause mixtures are made by physically combining two or more subtances.The solids,liquids,or gases in a mixture are not chemically combined.They can be easily seperated.
physical change because a mixture means that the 2 substances are not chemically combined so the 2 substances can be easily separated.
you would physically separate a mixture but would chemically separate a compound.
This depends on the specific situation and cost: chemical properties but also physical properties can be used for separation from mixtures.
Physical change.
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
Classifying chemicals by their chemical properties, like their chemical functions, or the way they react chemically, allows them to be grouped together according to their functions.
yes dissolving sugar in a coffee is a physical change in a chemical change a new substance will be formed, and the component of this substance will be different from the parent substance. but in the case of sugar dissolving in coffee, mixture of sugar and coffee retain their respective properties. Moreover we can also separate the constituents from that mixture.and there is no new substance is formed
Separation of mixtures is generally based on physical properties.
They tend to all have fairly similar chemical and physical properties and can be tricky to separate. Neodymium and praeseodymium in particular are hard to separate (the -dymium part comes from Greek "didymos" meaning "twin").
when you separate a substance from a mixture, it's a physical change... Technically, you can get it back in the mixture.
Physical because you are not changing the substance.
both
They have different molecular weights and chemical/physical properties.

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.
A physical change, and a chemical change.

A chemical property is the properties exhibited by a material in a chemical reaction. This gives a substance the ability to have a chemical identity and is also used in building chemical classifications. The properties can be used in identifying a substance that is unknown or to separate substances. The property also helps in providing information on the application of a substance.
The method of evaporation to separate substances in a mixture is purely physical because no chemical reaction occurs.
