Chemical Reactions and Equations is an important Class 10 Science chapter that explains how substances change into new substances. Students learn how to identify chemical changes, write chemical equations, balance equations, and classify different types of chemical reactions.
Questions from this chapter may ask students to identify reactants and products, balance chemical equations, apply the law of conservation of mass, recognise combination, decomposition, displacement, double displacement, oxidation, reduction, redox, exothermic, and endothermic reactions.
Use this 20-question practice test before broader Class 10 Science revision. After completing the test, review every explanation carefully and repeat the test after revising weak areas such as balancing equations, reaction types, oxidation-reduction, corrosion, and rancidity.
Focus on balanced equations, reaction types, redox reactions, corrosion, and rancidity.
Review reactants, products, chemical symbols, word equations, skeletal equations, balanced equations, and the law of conservation of mass.
Practice combination reactions, decomposition reactions, displacement reactions, double displacement reactions, precipitation reactions, exothermic reactions, and endothermic reactions.
Revise oxidation, reduction, redox reactions, corrosion, rusting of iron, rancidity, antioxidants, and methods to prevent rancidity.
Before repeating the test, make sure you can identify what changes during a reaction and how the equation represents that change. Most questions become easier when you first identify the reactants, products, and type of reaction.
Chemical Reactions questions often require careful observation of symbols, products, and reaction conditions. When checking your result, see whether one of these common mistakes affected your answer:
Turn a 20-question MCQ test into a focused Class 10 Science revision session.
Answer the full test without checking notes so that weak areas in equations and reaction types are easier to identify.
Decide whether the question is about combination, decomposition, displacement, double displacement, redox, or precipitation.
Read explanations for incorrect answers and for correct answers that were selected by guessing.
Revise the difficult reaction type or equation rule and complete the 20-question test again.
