limitation of heating element
If a substance undergoes a decomposition reaction, it is a compound. Pure elements cannot decompose because there is nothing for them to decompose into.
It depends on the substance your are talking about. It could be a compound, mixture, or substance; depending on the substance. If it is an element off the periodic table, it is an element. If it is two elements chemmically combined, it is a compound. If it is two elements that are not chemically combined, it is a mixture.
an element is a single substance while a compound is made up of multiple elements. Theirs no way to now how many elements form to make a compound... only through a microscope/
When one element is combined with another element, a chemical compound results. The elements are chemically bonded together to make this compound.
a pure substance! ;)
The formula of a substance(element or compound) tells us the number of molecules in the in the substance(element or compound).
If a substance undergoes a decomposition reaction, it is a compound. Pure elements cannot decompose because there is nothing for them to decompose into.
A pure substance is either an element or a compound.
I think that its a compound.
Steel is an alloy- which is a compound, or intermixture. So it is not an element or pure substance.

A compound is more that one element (an element is a single atom of a substance ie H hydrogen ) a compound is still considered to be a pure substance
This substance is a compound.
A pure substance is an element or a compound.
It is an element.
A compound or compound substance.
A substance that cannot be broken down is a pure substance
