Points to Remember
We have provided some important points that are covered in NCERT Class 11 Chemistry Chapter 1 to help students in their exam preparations. Refer to the list below:
In chemical classification, the matter is classified as mixtures, compounds and elements.
A homogeneous mixture has uniform composition and properties throughout while a heterogeneous mixture’s composition and properties are not uniform throughout.
The law of conservation of mass states that the total mass of all the products in a chemical reaction is the same as that of all the reactants present before the reaction.
The law of definite proportions states that a chemical compound is always made up of the same elements combined together in a fixed proportion by mass.
The law of multiple proportions states that when two elements combine to form two or more compounds, then masses of one of the elements which combine with a fixed mass of the other bear a simple ratio to one another.
The Gay-Lussac’s law of combining volumes states that volume of gaseous reactants and products bear a simple ratio to one another when measured under identical conditions of temperature and pressure.
Avogadro’s law states that equal volumes of all gases under similar conditions of temperature and pressure contain equal numbers of molecules.

Topics and Sub-Topics
Chemistry is very important because it covers all areas of life. Chemists study the properties and structure of matter and the changes it undergoes. All substances include substances that can be in three states: solid, liquid or gas. In this chapter, students learn about the properties of substances and the chemical laws of their combinations. This chapter helps students build a solid foundation for learning chemistry. This will help students learn about atomic and molecular masses as well as moth concepts, chemical reactions, and molecular formulas.
Therefore, the exercises included in this chapter will help students better understand the concepts. Students will be introduced to the law of conservation of mass, the law of specific proportions, the law of multiple ratios, the International System of Units, weights and measures, and weight. Weight from an inspection point of view.
Read the entire chapter carefully before answering the questions.
