PSEB Class 10 Chemical Reactions Practice

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.

What to Review for Chemical Reactions

Focus on balanced equations, reaction types, redox reactions, corrosion, and rancidity.

Chemical Equations

Review reactants, products, chemical symbols, word equations, skeletal equations, balanced equations, and the law of conservation of mass.

Types of Reactions

Practice combination reactions, decomposition reactions, displacement reactions, double displacement reactions, precipitation reactions, exothermic reactions, and endothermic reactions.

Oxidation and Daily Life

Revise oxidation, reduction, redox reactions, corrosion, rusting of iron, rancidity, antioxidants, and methods to prevent rancidity.

Key Chemical Reactions Concepts to Remember

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.

Common Mistakes in Chemical Reactions Questions

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:

  • Confusing reactants with products
  • Forgetting to balance chemical equations
  • Changing chemical formulas while balancing equations
  • Balancing oxygen or hydrogen before checking all elements
  • Confusing combination reaction with decomposition reaction
  • Confusing displacement reaction with double displacement reaction
  • Forgetting that a precipitate is an insoluble solid
  • Confusing oxidation with reduction
  • Forgetting that oxidation can mean addition of oxygen
  • Forgetting that reduction can mean removal of oxygen
  • Calling every reaction exothermic
  • Confusing corrosion with rancidity
  • Forgetting that rusting needs air and moisture
  • Forgetting that rancidity affects oils and fats
  • Ignoring symbols such as heat, light, or electricity in decomposition reactions

Chemical Reactions Practice FAQ

Common questions about this PSEB Class 10 Science Chemical Reactions practice test.

Yes. The Chemical Reactions practice test is free to use and does not require registration, payment, or a subscription.

The test contains 20 multiple-choice questions with four answer options, instant result checking, and detailed explanations.

Review chemical equations, balancing equations, law of conservation of mass, combination reactions, decomposition reactions, displacement reactions, double displacement reactions, oxidation, reduction, corrosion, and rancidity.

A chemical reaction is a process in which one or more substances change into new substances with different properties.

Chemical equations are balanced because mass is conserved during a chemical reaction. The number of atoms of each element must be equal on both sides of the equation.

A combination reaction is a reaction in which two or more reactants combine to form a single product.

A decomposition reaction is a reaction in which one compound breaks down into two or more simpler substances.

Yes. Review the explanations, revise difficult concepts, and complete the 20-question test again whenever you need additional practice.

No. The questions are original PSEB-style educational practice material. They are not copied from official Punjab School Education Board examination papers.
