A chemical substance is a material with a specific chemical compound.
A common example of a chemical substance is pure water; it has the same properties and the same ratioof hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Some typical chemical substances are diamond, gold, salt (sodium chloride) and sugar (sucrose). Generally, chemical substances exist as a solid, liquid, or gas, and may change between these phases of matter with changes intemperature or pressure. Chemical reactions convert one chemical substance into another.
Forms of energy, such as light and heat, are not considered to be matter, and thus they are not "substances" in this regard.

I don’t know
Are there more pure substances or mixtures found in the world?
mixtures
Is a solubility a Prue substances or a mixtures?
Solubles are homogenous mixtures.
Substances are divided into two classes?
Some people divide matter into pure substances and mixtures. Pure substances are elements and compounds. Mixtures include homogeneous and heterogeneous mixtures. Some people divide matter into homogeneous matter and heterogeneous matter. Homogeneous matter includes pure substances and homogeneous mixtures (solutions). Heterogeneous matter is heterogeneous mixtures.
Mixtures are?
Mixtures are materials made up of two different substances which do not combine chemically.
Do heterogeneous mixtures combine to form compounds?
No. Heterogeneous mixtures are not compounds.
What is formed when two substances combine and form a new substances combine and form a new substance which cannot return to their original form?
a chemical reaction
Do elements that combine in changing ratios form mixtures?

When substances combine to form a compound what happens to the original properties of the substances?
When substances combine and retain their own properties, the result is a mixture.
What are two or more substances placed together but do not combine?
These substances form a mixture.
reactivity?
The ability of two or more substances to combine to form other substances.
