A substance that is chemically combined cannot be separated physically.
In some situations, you can and can't separate combined substances physically. For example, you can separate sand from rocks physically, but you cannot separate water and ice cream, even though the substances did not undergo a chemical change, because the water soaked into the ice cream.
Depends on the substances but I'd say no
It is a substance.
Generally speaking, yes but ...It depends on what the substance is and what you want to separate.If the substance is a mixture of sugar and water then the water can be evaporated off and the sugar remains behind.Water, H2O, itself is not a mixture but a pure substance and it, too, can be separated into hydrogen and oxygen by running an electrical current through it to break the bonds in the molecules.Some substances like paint can have its components forensically determined by running a sample through a gas chromatographwhich will analyse the components of the paint to determine which brand it is which batch it came from and maybe help solve a crime. The gas chromatograph is used for small samples and does not separate larger samples back into its components.

A substance can be categorized into several categories. If a substance cannot be separated through physical means (e.g., distillation, magnetism) it is a pure substance. If a substance can be separated through physical means, it is a mixture. If a mixture is uniform throughout, it is a homogenous mixture, like saltwater. If it is not (i.e., there are different parts to it, like a can of soda), it is a heterogeneous mixture. If a pure substance can be separated through chemical means, it is a compound, like glucose, which is made of carbon, oxygen, and hydrogen. If a substance cannot be separated by chemical means, it is an element, like oxygen, which is made of just oxygen. A substance can be in multiple categories.
compound
A Compound is a chemically combined entity. It cannot be separated physically. A Solution is a physically combined entity. Hence, it can be separated physically.
The components of a mixture are physically combined.
Any substance or compound cannot be physically separated. The broad term for this is simply "substance".
Pure substances that are physically combined make a mixture.
If it was chemically combined, then no. If it was physically combined, then yes.
Element.
It's a compound
mixture
What are the components of solutions?
it depends on wht compound it its
A substance you can't physically change would be copper grains, and iron filings.
The substance is a compound, which forms chemical bonds that cannot be physically separated, but only by a chemical change.
