This Class 10 General Knowledge topic, presented in the Chemistry GK chapter, introduces students to how substances change into new substances through chemical reactions. It explains common signs of a reaction, such as colour change, gas formation, temperature change and precipitate formation, along with basic reaction types including combination, decomposition, displacement and oxidation. Students also connect these ideas with everyday examples, conservation of mass, corrosion, combustion and safe chemical practices.
