CBSE Class 10 Science Chapter 1 - Chemical Reactions and Equations
Brief Information: The first chapter of Class 10 NCERT Science will teach the students about chemical reactions and how to write equations, how to conduct combination and decomposition reactions and more. In the previous classes, we have learned about physical and chemical changes of matter. Whenever a chemical change occurs, we can say that a chemical reaction has taken place. A complete chemical reaction represents the reactants, products and their physical states symbolically. Students will also study how to write a chemical reaction, which is a symbolic representation of a chemical reaction. The chapter also explains how various chemical equations can be balanced in different states.
The next subtopic teaches about various chemical reactions such as Combination Reaction, Decomposition reaction, Displacement Reaction, and Double Displacement Reaction along with various examples and chemical reactions. On the basis of energy, exothermic and endothermic reactions are explained. Exothermic reactions are those reactions in which heat is given out along with the products and endothermic reactions are those reactions in which energy is absorbed. Then redox reaction is explained, which is a combination of reduction reaction and oxidation reaction. The chapter explains all types of reactions with suitable examples with their respective chemical equations.
