mixture
if a materials composition varies from region to region it can be classified as what
A chemical change involve a change of composition.
Mostly Silica (SiO2) in the form of quartz. The rest of the composition varies greatly depending on climate and location.
Several chemical properties can be estimated knowing the chemical composition.
A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes

Chemistry is the scientific study of the composition structure and properties of matter and the changes that it undergoes.
Chemistry is the name of the science which studies composition, matter and structure.Specifically, the science in question deals with matter - elements which have mass and weight - and substances. It emphasizes the composition and properties of matter and substance. It also examines structure.
Chemists study the composition of all matter at the atomic and molecular level. They analyze the structure, properties, and reactions of substances to better understand their composition.
Chemistry
Matter with a definite composition is a pure substance, such as an element, molecule, molecular compound, or ionic compound.
The term for matter having indefinite composition and variable properties is a mixture. Mixtures can be homogeneous (uniform composition) or heterogeneous (non-uniform composition).
