Chemical Reactions and Equations | Class 10th | CBSE | ICSE boards

Chemical Reactions and Equations introduces students to the fundamental process through which substances change into new substances with different properties. The chapter explains how reactions occur, how to write chemical equations, and why balancing them is essential for following the law of conservation of mass. What This Chapter Covers 1. Understanding Chemical Reactions Chemical reactions involve the breaking of old bonds and formation of new ones. Students learn how these changes indicate chemical transformations through signs like colour change, heat, gas formation, and precipitates. 2. Writing Chemical Equations This part teaches how to represent reactions using symbols and formulas. It also explains reactants, products, and how to convert word equations into chemical equations. 3. Balancing Chemical Equations Balancing ensures that atoms are conserved on both sides of the equation. The chapter introduces simple rules to balance equations systematically. 4. Types of Chemical Reactions The chapter includes combination, decomposition, displacement, double displacement, oxidation, and reduction reactions, along with real-life examples. 5. Effects of Oxidation and Reduction It covers corrosion, rancidity, and practical ways to prevent them, helping students relate chemical processes to daily life.
