Astudent hears in chemistry class that a certain object is made of a pure substance. what can the student conclude about the object based on this information?

The object is made up either elements or a compound.

Explanation:

A pure substance is defined as the substance which is formed by same or different type of atoms which are chemically combined in a fixed ratio by mass.

Elements and compounds are considered as pure substances.

Elements are formed by the combination of similar type of atoms and compounds are formed by the combination of different type of atoms.

We are given:

An object is made of a pure substance.

Hence, the object is made up either elements or a compound.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.
