Chapter 1 Chemical reactions and equations

NCERT Science Class 10 Chapter- 1 will teach students about chemical reactions, how to write equations, how to perform combination and decomposition reactions, and more. In previous lessons, we learned about physical and chemical changes in matter. Whenever a chemical change take place, we can say that a chemical reaction occurs. The complete chemical reaction represents the reactants, products, and physical states. Students will also disucss how to write a chemical reaction, a symbolic representation of a chemical reaction. The chapter also explains how different chemical equations can be balanced in different states.

Another subtopic teaches various chemical reactions, such as combination reactions, decomposition reactions, displacement reactions, and double displacement reactions, along with different examples and chemical reactions. Based on energy, exothermic reactions and endothermic reactions are explained. A exothermic reactions are reactions in which heat is released along with products, and endothermic reactions are reactions in which energy is absorbed. Next, a redox reaction is explained, combining a reduction reaction and an oxidation reaction. The chapter explains all reactions with suitable examples with relevant chemical equations.

Topics Covered in this chapter are- Chemical reactions: Chemical equation, types of chemical reactions, Balanced chemical equation, implications of a balanced chemical equation: combination, displacement, decomposition, double displacement, precipitation, endothermic exothermic reactions, oxidation, and reduction.

Chapter 2 Acids, bases and salt

In everyday life, we come across different things of different tastes. For example lemon tastes sour and bittergourd tastes bitter. The sour and bitter tastes of food are due to acids and bases present in them. Excess of an acid in the stomach can cause acidity which can be neutralized by giving a base. This is because, whenever an acid reacts with a base, a salt is formed, which is neutral in nature. More interesting facts, properties and uses of acids, bases and salts will be discussed in this chapter.

Topics Covered in this chapter are- Acids, bases, and salts: Their definitions in terms of furnishing of H+ and OH– ions, General properties, examples and uses, neutralization, the importance of pH in everyday life, concept of pH scale (Definition relating to logarithm not required); preparation and uses of Sodium Hydroxide, Bleaching powder, Baking soda, Washing soda and Plaster of Paris.

Chapter 3 Metals and Non-metals

At present, more than 114 chemical elements are known. Many of them are found to occur in nature whereas some of them have been made by artificial methods and are called synthetic elements. Each element has a set of characteristic properties.

To make the study of these elements easier, they are grouped on the basis of their common properties into two classes––metals and non-metals. Different metals and non-metals have different physical and chemical properties. Therefore, they are used also in a different manner. We will read about this in detail in the following chapter.

Topics Covered in this chapter are- Metals and Nonmetals: Properties of metals and non-metals;Formation and properties of ionic compounds; Reactivity series; Basic metallurgical processes; Corrosion and its prevention.

Chapter 4 Carbon and Its Compounds

Carbon is an element which is of immense significance to us in both its elemental form and in the combined form. Food, clothes, medicines, books or many of the things are all based on this versatile element carbon. All living structures are carbon based. The earth’s crust has only 0.02%.

Carbon in the form of minerals (like carbonates, hydrogen-carbonates, coal and petroleum) and atmosphere has 0.03% of carbon dioxide. In spite of this small amount of carbon available in nature, the importance of carbon seems to be immense.In this chapter, we will be studying the properties of carbon which lead to this anomaly.

Topics Covered in this chapter are- Carbon compounds: The versatile nature of carbon, Covalent bonding in carbon compounds, and homologous series. Nomenclature of carbon compounds containing functional groups (alcohol, halogens, ketones, aldehydes, alkanes, and alkynes), the difference between unsaturated hydrocarbons and saturated hydrocarbons. Chemical properties of carbon compounds (combustion, addition, oxidation, and substitution reaction). Ethanol and Ethanoic acid (only properties and uses), soaps, and detergents.

Chapter 5 Periodic Classification of Elements

In Standard 9, we learned that matter around us is present in the form of elements, compounds, and mixtures, and elements contain only one type of atom. Early attempts to classify the elements resulted in grouping the then-known elements as metals and nonmetals. Dobereiner grouped the elements into triads, and the Newlands gave the "Law of Octaves." The mandelvee arranged the elements in increasing order of their atomic weights according to their chemical properties. He also predicted the existence of some yet-to-be-discovered elements based on gaps in his periodic table. The modern periodic table was created. The Mendeleev's periodic law was modified, and the atomic number was adopted as the basis of the modern periodic table. The modern periodic law states: 'The properties of elements are a periodic function of their atomic number.'

In this chapter, Periodic Classification of the Elements, the elements in the modern periodic table are arranged in 18 vertical columns known as groups and 7 horizontal rows called dots. Elements arranged in this way exhibit a periodicity of properties, including atomic size, valence or combining capacity, and metallic and non-metallic character. The valence of an element is represented by the number of valence electrons present in the outermost shell of its atom. The atomic size indicates the radius of an atom.

Chapter 6 Life Processes

NCERT Class 10 Science Chapter-6 discuss about Life Processes. There are six life processes that all living organisms perform. They are movement, respiration, growth, reproduction, excretion, and nutrition. The chapter also teaches about nutrition, which means the process of taking in food and using it for growth, metabolism, and repair. The nutritional phases are reception, digestion, absorption, transport, assimilation, and excretion.

Nutrition is further divided into autotrophic nutrition and heterotrophic nutrition. Autotrophic nutrition involves taking in simple inorganic materials from the environment and using an external energy source, such as the Sun, high-energy organic material, to synthesize complex. An heterotrophic nutrition involves the intake of complex material prepared by other organisms. Types of heterotrophic nutrition are parasitic, saprophytic, and holozoic. Another topic is human nutrition. The different nutrition steps are ingestion, digestion, esophagus, stomach, small intestine, bile, absorption, assimilation, and egestion.

Another subtopic is breathing, in which the human respiratory system is beautifully explained. The various elements of the human respiratory system are the lungs, bronchi, larynx, pharynx, etc. During the process of respiration, organic compounds such as glucose are broken down to provide energy in the form of ATP. The ATP is used to distribute energy for other reactions in the cell.

Respiration can be aerobic or anaerobic. Aerobic respiration makes more energy that is available to the body. The soil is the closest and richest source of raw materials such as nitrogen, phosphorus, and other minerals for plants. In humans, transporting materials such as oxygen, carbon dioxide, food, and excretory products is a function of the circulatory system. The circulatory system includes heart, blood, and vessels.

In highly differentiated plants, the transport of water, minerals, food, and other materials is a function of vascular tissue, which consists of the xylem and phloem. In humans, excretion products in the form of soluble nitrogen compounds are removed by kidney nephrons. Plants use different techniques to get rid of waste material. Topics Covered in this chapter are- Life processes: ‘Living Being’. Basic concept of nutrition, respiration, transport and excretion in plants and animals.

Chapter 7 Control and Coordination

NCERT Solution of Class 10 Chapter 7 teaches about control and coordination, which are the hormones and nervous system functions in our body. Nervous system responses can be classified as reflex action, involuntary action, or voluntary action. A nervous system uses electrical impulses to transmit messages. It receives the information from the sense organs and acts through our muscles. The chemical coordination is seen in both plants and animals. A hormone produced in one part of the body moves to another to achieve the desired effect. A feedback mechanism regulates the action of hormones.

Topics Covered in this chapter are- Control and co-ordination in animals and plants: Tropic movements in plants; Introduction of plant hormones; Control and co-ordination in animals: Nervous system; Voluntary, involuntary and reflex action; Chemical co-ordination: animal hormones.

Chapter 8 How do Organisms Reproduce?

Reproduction is an important process which distinguishes living organism from non-living. Reproduction is not necessary to maintain the life of an individual unlike the essential life processes like nutrition, respiration, excretion, etc. Moreover a lot of energy is spent to produce more individuals.

But then, why do organisms reproduce? The different individuals of a species share many common characters. Also, we see the offsprings of one parent have certain differences. How do organisms reproduce? Let us discover our inquisitiveness in this chapter. Topics Covered in this chapter are- Reproduction in animals and plants (asexual and sexual) reproductive health – need and methods of family planning. Safe sex vs HIV/AIDS. Child bearing and women’s health.

Chapter 9 Heredity and Evolution

Every organism reproduces either asexually or sexually to produce offsprings, which are similar to the parents. However, offsprings show some variations from their parents and also among themselves, so that each one has its own individual identity. Have you seen any two human beings exactly alike except the identical twins? Besides this, origin of life on earth is an established fact. By the process of gradual and continuous change, living organisms have evolved to exhibit such a wide diversity. In the following chapter, we will learn about heredity and sex-determination and also about evidences and theories of evolution.

Topics Covered in this chapter are- Heredity; Mendel’s contribution- Laws for inheritance of traits: Sex determination: brief introduction: (topics excluded – evolution; evolution and classification and evolution should not be equated with progress).
