Is Granite A Pure Chemical Substance

Impure materials may be mixtures of elements mixtures of compounds.

Is granite a pure chemical substance.

A pure chemical substance is any matter that has a fixed chemical composition and characteristic properties. But there are exceptions to this definition. A pure substance or chemical substance is a material that has a constant composition is homogeneous and has consistent properties throughout the sample. A pure substance is by definition composed of one compound.

In chemistry a pure substance consists of only one type of atom molecule or compound. Pure and impure chemical substances a pure element or compound contains only one substance with no other substances mixed in. All matter consists of various elements and chemical compounds but these are often intimately mixed together. Just like granite marble is a mixture.

Common definition of a pure substance. All samples of sodium chloride are chemically identical. Very few samples of matter consist of pure substances. In other words it is free of contaminants.

However unlike granite marble is typically more than 90 calcium carbonate so it might count as a pure substance. A pure substance participates in a chemical reaction to form predictable products. However unlike granite marble is typically more than 90 calcium carbonate so it might count as a pure substance. So in addition to elements compounds and alloys a pure substance might include honey even though it consists of many different types of molecules.

So option b sodium chloride is a right option. According to this definition a chemical substance can either be a pure chemical element or a pure chemical compound. A pure substance can also be defined as a form of matter that has both definite. Mixtures contain more than one chemical substance and they do not have a fixed composition.

A compound may be composed of different elements. It is considered a pure substance because it has a uniform and definite composition. Ordinary table salt is called sodium chloride. To a non chemist a pure substance is anything composed of a single type of material.
