NCERT Solutions for Class 10 Science Chapter 1: Important Topics

In this chapter, students will learn about the chemical changes happening around them. They will learn how substances react with each other to form new substances with new properties and how these changes are represented by chemical equations. There are many types of chemical reactions. Substances can combine to form a new substance or decompose to form new substances.

Different compounds can also be formed by displacing an element in another substance or by exchanging elements. All of these chemical reactions involve the release or absorption of energy. In this chapter, students will also learn common examples of such reactions, such as rusting and corrosion.

NCERT Solutions for Class 10 Science Chapter 1: Points to Remember

We have provided some important points to remember from 10th NCERT Science Chapter 1 for students to refer to for exam preparations:

• Changes in which new substances are formed with entirely new properties are called chemical changes/chemical reactions.
• Chemical reactions are characterised by some easily observable features like evolution of a gas, formation of precipitate and change in colour, temperature or state.
• The reactions in which heat is evolved are known as exothermic reactions while the reactions in which heat is absorbed are known as endothermic reactions.
• A balanced chemical equation is an equation which has an equal number of atoms of each element on both reactant and product sides.
• A chemical equation can be made more informative by mentioning physical states of the substances involved, heat changes involved in the reaction and conditions under which the reaction takes place.
• The reaction in which two or more reactants combine together to form a single product is called a combination reaction. In all combination reactions, heat is evolved i.e., all combination reactions are exothermic.
• The reaction in which a single reactant breaks down to give two or more simpler products is called a decomposition reaction. For decomposition reactions, energy must be supplied either in the form of heat, light or electricity i.e., decomposition reactions are endothermic.
• The reaction in which a more reactive element displaces a less reactive element from its compound is called displacement reaction.
• The reaction in which two compounds react by an exchange of ions to form two new compounds is called double displacement reaction.
