<span> A pure substance is an material which contains atoms of only one kind.
It has fixed physical and chemical properties such as boiling point, melting point, valency, density and more.</span>
True. In order for a chemical reaction between elements/compounds, the atoms within the chemicals must have sufficient energy in order to be able create a reaction.
