Important Topics for NCERT Chemistry Exemplar Solutions Class 11 Chapter 1 – Some Basic Concepts of Chemistry

Nature of Chemistry

The nature of chemistry is defined as the study of the composition, structure, and characteristics of matter and of changes that occur in matter. The matter is defined as the building block material of the universe. It is something that occupies space and has mass.

Laws of Chemical Combination

Laws of Chemical Combination defines that a substance can neither be created nor destroyed. It explained that a given multiple always comprises exactly the similar proportion of elements by weight. There are five basic laws that rule the chemical combination of elements. They are listed as follows:

Law of Multiple Proportions: It is a law of stoichiometry expressed by John Dalton.

Law of Conservation of Mass: This law states that throughout a chemical reaction, the mass of the products and reactants will always be identical.

Law of Definite Proportions: This law states that every chemical compound will cover a fixed and continuous proportion by mass, of its basic elements. This law was proposed by Joseph Proust.

Gay Lussac’s Law of Gaseous Volumes: Gay Lussac provided this law in the year 1808. This law was correctly described by Avogadro.

Avogadro Law: Avogadro Law states that when the temperature and pressure conditions are similar, gases of equal volumes comprise a similar number of molecules.
