Lakhmir Singh Solutions for Class 9 Chemistry Chapters

 

Chapter 1- Matter and Surroundings

The first chapter of class 9, Chemistry "Matter and Surroundings," deals with the relation of matter with the surroundings. Matter is defined as a substance that has mass and occupies space. In this chapter, the students will learn various terms related to matter and the classification of matter. The chapter introduces students to the concepts of matter for providing them with fundamental knowledge about the matter and its classification. Students will find this chapter simple as it majorly consists of theory and its explanation in detail. Chapter 1 Matter and Surroundings discusses the number of ways in which matter can be classified. Matter can be classified into three types based on physical properties. The matter can be classified as solid, liquid and gas.
Solids - Molecules are closely packed and have a definite shape
Liquids - No definite shape and volume
Gases - These neither have shape nor volume

The chapter will explain the classification of matter in detail using various examples and diagrammatic representation. Based on chemical properties, the matter is classified into elements, compounds and mixtures. The chapter explains the chemical properties of matter in detail with many examples and simple explanations.

Chapter 1 Matter and Surroundings further discusses the characteristics of matter such as shape, volume and density. Students will also get to study the changes of states in this chapter. The characteristics are explained in an interactive way using figures and diagrams so that students find the chapter and the topics easy to understand. The terms, definitions, and explanations explained in the chapter are very important to build basic knowledge of the subject for the students. If they learn and remember the chapter, then they will find the upcoming chapters simpler. The topics covered in Chapter 1 Matter and Surroundings are matter in our surroundings, physical state of matter, characteristics of particles of matter, states of matter, matter changes its state, evaporation, and so on. The topics introduced in this chapter will be repeated further in upcoming chapters and at an advanced level in the upcoming higher classes.

Chapter 2- Is Matter Around Us Pure

Anything that occupies space and has mass is known as matter. Chapter 2 Is Matter Around Us Pure deals with elements, compounds and mixture. The matter can exist in two types as Pure substances and Mixtures. The chapter will introduce students to many definitions and explanations in the chapter. The examples are included in the chapter wherever needed. Pure substances - Pure substance is made up of only one type of particles (atoms or molecules) Mixtures - Mixtures are of two types which are a homogenous mixture and heterogeneous mixture. After going through the topics given in Chapter 2, Is Matter Around Us Pure, students will differentiate between types of matter.

Chapter 2 Is Matter Around Us Pure further discusses the properties of metals, non - metals and metalloids. The students shall study metals, non - metals, metalloids and their properties in detail. Everything has been explained well with the help of examples. Metals - A metal is defined as an element that forms positive ions and conducts electricity. Non - metals - A non-metal lacks the characteristics of a metal. As a result, they are poor conductors of electricity. Metalloids - Metalloids are the elements that show the properties of both metals and non - metals. Many new concepts have been introduced and explained well in this chapter that are related to the matter.

Chapter 2 Is Matter Around Us Pure then proceeds with the differentiation of compounds. The chapter is absolutely a concept based on theoretical explanations of various topics and terms. Students have to practice answering questions given in the exercises to remember the concepts and formula. They can prepare well for the exam if they revise and brush up on their concepts promptly. Chapter 2 Is Matter Around Us Pure is very simple to understand and learn. This will help students to score good marks in the exam. The topics and subtopics covered in this chapter are mixtures, suspension, colloids, suspension, solutions etc. Students will find reading the theory of this chapter very interesting.

Chapter 3- Atoms and Molecules

Atom is defined as the smallest particle of the chemical element. Chapter 3 Atoms and Molecules discusses the law of combinations that explains three important laws. First, all the matter that exists is made up of small particles known as atoms and molecules. Second, a molecule is defined as a group of two or more atoms and is electrically neutral. Chapter 3 Atoms and Molecules is the most fundamental chapter for class 9 Chemistry as it consists of the basics that students will learn about at an advanced level in the upcoming higher classes. Henceforth, students should pay great attention to this chapter and practice questions as much as possible using exercises and solved examples. This will help students to enhance their problem-solving skills.

Chapter 3 Atoms and Molecules focuses on the concept of an atom by explaining various theories given by different scientists. Dalton's atomic theory explains that all matter comprises very tiny indivisible particles known as atoms. The drawbacks of this theory are also explained in the chapter. The chapter further discusses atomic mass, molecular mass and gram molecular mass with the help of various examples.

Chapter 3 Atoms and Molecules consist of the law of chemical combination, atom, molecule, writing chemical formula, molecular mass and mole concept. Few topics out of the mentioned topics repeat themselves in many coming chapters and even in higher classes. The mole concept is defined as the total number of calculated molecules that take part in a chemical reaction. The concept will be explained in detail in this chapter. There are various questions given in the textbook based on the mole concept. Practising and revising numerical related to molecular mass and mole concept is a must. Students will score really good marks in class 9 Chemistry if they master Chapter 3 Atoms and Molecules.
