A compound.A compound is composed of elements. If you were to break down a compound you would get new compounds or elements.
Yeah, so compound just separate by chemical means. It's always been like that and that's the way that it will no doubt stay
a chemical reaction transforms a substance into another. in this case, the melting ice would only add more water to your tea, which is already composed primarily of water, infused with tea (leaves). ice melting is only changes the state of the substance--the substance itself does not change!
A compound can only be separated into elements by chemical means.
A chemical reaction starts with reactants and results in products.
The substance is a compound, which forms chemical bonds that cannot be physically separated, but only by a chemical change.
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'.
Yes.

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.
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
If the item changes form and substance chemically.
The components of a mixture can be separated by physical means, such as filtration or distillation. The components of a compound can be separated only by chemical means, meaning a chemical reaction.
Matter is a pure substance if it can only be separated by chemical means, NOT physical means. This could be a compound or an element. The opposite is a mixture which can be separated/broken into smaller parts by physical means.

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
