If a substance can be physically separated into its components is it a pure substance or a mixture?

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.


What element or compound cannot be physically separated?

An element or compound that cannot be physically separated is an atom. Atoms are the smallest unit of matter that retains the properties of an element and cannot be further broken down by physical means. Compounds, on the other hand, can be separated into their individual elements through chemical reactions.


What is substance can be separated into simpler substance is only by chemical means?

The substance is a compound, which forms chemical bonds that cannot be physically separated, but only by a chemical change.


What is a substance made of 2 or more different atoms that cannot be physically separated?

Elements


What substance cannot be separated physically but can be separated chemically?

A compound, such as water (H2O), cannot be physically separated into its component elements (hydrogen and oxygen) but can be chemically separated through a chemical reaction, such as electrolysis, which breaks the bonds between the elements.

What is difference between a compound and solution?

Can a combined substance be separated physically?

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.


What do you call matter that can't be physically Separated?

I believe that we call matter that can no longer be separated into unique parts an atom. You cannot get any smaller than an atom and still have a recognizable substance. We can separate molecules into individual atoms. Elements consist of the same type of atom (i.e. gold is an element because it consists entirely of the atoms with the same number of protons and neutrons).


When matter cannot be separated into more than one substance by physical or chemical means it is called?

A pure substance.


Substance that can't be separated?

An example of a substance that cannot be separated into simpler substances by physical or chemical means is an element like gold or oxygen. Elements are made up of only one type of atom, so they cannot be broken down further by ordinary methods.
