A mixture or a substance (Compound) - yes; an element - not.
in chemistry, chemical substance is a form of matters that has constant chemical composition and characteristic properties.it cannot be separated into components by physical separation methods. mixtures are the product of mechanical blending or mixing of chemical substance like elements and compounds ,without chemical bonding or other chemical change.
A compound.A compound is composed of elements. If you were to break down a compound you would get new compounds or elements.
Bye using a chilsele hamer of any other substance tht is hard enought to brake it
Yes,mixing with other compounds can change the properties of a substance. The melting point, boiling point changes. Chemical properties are also can be changed.
The way you phrase that is a little dubious because no mixture is a 'pure substance'. However, compounds like iron sulphide that are actually bonded together areconsidered pure substances. The elements of a mixture are not united by a chemical change and can (in theory) be separated.
The substance is a compound, which forms chemical bonds that cannot be physically separated, but only by a chemical change.

You're only changing the form of the substance, not the chemical compounds in it.
its a chemical change. a physical change does not change the chemical makeup of a substance. it simply changes its form or physical state. examples: ice melting, a tree being chopped down.
A chemical change can help you tell the difference between an element and a compound because an element is a pure substance that cannot be broken down or separated into other pure substances through chemical change while a substance that is made from two or more elements that have combined in a chemical change are known as compounds.
With ionic compounds anyway, they dissociate into their ions. The chemical change is an equilibrium until separated.

A pure substance is a substance that cannot be separated by means of physical separation but only by chemical. It is a change in time.
A Substance that can be separated into two or more substances is call a Composition, if not try Solution.----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- -----From Rafaelrz.Yes. A substance that can only be separated into two or more substances by a chemical change is a 'compound'. If a body can be separated into two or more different substances by only physical processes, then the body is a 'mixture'.
Elements
A mixture There are four types of mixtures: Alloy - homogenous metalic solid Solution - homogenous mix of two or more substances (not all metals) Suspention - not evenly mixed and will separate if left alone Colloid - Sorry, I always forget what this one is
