Is Matter Around Us Pure?

Matter around us is of two types - pure substances and mixtures. Pure substances are further divided into elements and compounds. Mixtures can be classified as homogeneous or heterogeneous mixtures.

Pure Substances

Pure substances are defined as substances that are made up of only one type of particles. They can be classified as elements and compounds.

Elements

Elements are substances that cannot be chemically broken down into simpler substances. They are made up of only one type of atom. Examples of elements are gold, silver, oxygen, hydrogen, etc.

Compounds

Compounds are substances that are made up of two or more different types of atoms chemically combined in a fixed proportion. Examples of compounds are water, carbon dioxide, sodium chloride, etc.

Mixtures

Mixtures are defined as substances that are made up of two or more pure substances mixed together. They can be classified as homogeneous and heterogeneous mixtures.

Homogeneous Mixtures

Homogeneous mixtures are mixtures that have a uniform composition throughout the mixture. The particles in a homogeneous mixture are evenly distributed. Examples of homogeneous mixtures are saltwater, sugar water, air, etc.

Heterogeneous Mixtures

Heterogeneous mixtures are mixtures that have a non-uniform composition throughout the mixture. The particles in a heterogeneous mixture are not evenly distributed. Examples of heterogeneous mixtures are sand and water, oil and water, etc.

Pure or Impure Mixture

A mixture can be pure or impure depending on whether it contains only one type of particle or not. If a mixture contains only one type of particle, then it is a pure mixture. If a mixture contains two or more types of particles, then it is an impure mixture.

Conclusion

In conclusion, matter around us can be classified as pure substances or mixtures. Pure substances are made up of only one type of particle, and mixtures are made up of two or more types of particles. Mixtures can be further classified as homogeneous or heterogeneous mixtures. A mixture can be pure or impure depending on whether it contains only one type of particle or not.

Impure becoz it is made up from two or more than two substances .
