Chapter 1 Chemical Reactions and Equations
Chapter 1: Chemical Reactions and Equations launches Class 10 Science students into the world of chemistry, building on Class 9 foundations while introducing advanced concepts crucial for board exam success and competitive preparation.
This high-weightage chapter systematically covers writing and balancing chemical equations, five major reaction types (Combination, Decomposition, Displacement, Double Displacement, Redox), exothermic vs. endothermic reactions, and practical applications like corrosion (rusting prevention methods) and rancidity (food preservation techniques). Students master balanced equation writing, reaction identification through observable changes (gas evolution, precipitate formation, heat/color changes), and Law of Conservation of Mass applications.
Through this online course module, conquer NCERT textbook experiments (zinc + copper sulphate, silver chloride precipitation), balancing 75+ equations, previous 05-year board questions, HOTS numericals, and MCQ practice with animated reaction mechanisms, real-life demonstrations (respiration, photosynthesis, battery operation), and exam-pattern mock tests.
