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.
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 substance formed by the chemical combination of two or more elements in fixed proportions. A solution is a homogeneous mixture of two or more substances where one substance (solute) is dissolved in another substance (solvent).
A substance that cannot be separated physically is a pure substance.
In a mixture, the substances are physically combined, meaning their identities and properties remain unchanged. Each component retains its individual chemical properties and can be separated by physical means.
Pure substances that are physically combined make a mixture.
If it was chemically combined, then no. If it was physically combined, then yes.
Element.
If a substance can be physically separated into its components, it is a mixture, not a pure substance. A pure substance consists of only one type of particle and cannot be separated into other substances by physical means.
The opposite of a pure substance is a mixture.
No, a mixture is not a substance. They are two different items. A mixture is when two or more substances are mixed together using any proportions but can be separated physically. A substance is when two or more compounds or elements are combined chemically into fixed proportions but can only be separated chemically.
A mixture is when two or more substances are physically combined but can be separated by physical means, such as filtering or distillation. The substances in a mixture retain their individual properties and do not undergo a chemical reaction.
it depends on wht compound it its
The substance is a compound, which forms chemical bonds that cannot be physically separated, but only by a chemical change.
