Yea an element can not be broken down anymore but a compound is a group of elements
The only way to break down a compound is through a chemical reaction.
Compound, crystal is not an element so obviously what it is made up of must be a compound <><><><> Crystals can be either an element (diamonds are carbon- and crystalline) or a compound (salt, sugar). Unsure of your meaning of "broken down".
yes
it is a compound, an element is a substance which can not be broken down into anything else through chemical processes
Ammonium compound breaks down into nitrites, and back to nitrates
The product of a decomposition reaction can be either a compound or an element. It depends on the specific reactants involved in the reaction. If a compound breaks down into simpler compounds or elements, the product will be a compound or element.
A substance that cannot be broken down is a pure substance
A compound
Sulfuric acid is an element known to break down paper, as it reacts with the cellulose in the paper to break it down into simpler compounds.
Soap is a compound mixture, an element cannot be broken down into smaller parts. Soap can be broken down into the parts that made it. Elements are pure.
If an something is an element you will not be able to break it down any further by chemical means.
