FAQs on Class 10 Science Chapter 1 MCQ

1. What is a chemical reaction?
   A chemical reaction is a process where one or more substances (reactants) are transformed into new substances (products) with different chemical compositions.
2. Why is balancing chemical equations important?
   Balancing chemical equations is necessary to satisfy the Law of Conservation of Mass, which states that mass can neither be created nor destroyed in a chemical reaction.
3. What are the main types of chemical reactions covered in Class 10 Chapter 1?
   The main types include Combination reactions, Decomposition reactions, Displacement reactions, Double displacement reactions, and Oxidation-Reduction (Redox) reactions.
4. What is an exothermic reaction?
   An exothermic reaction is one that releases heat energy along with the formation of products, such as combustion or respiration.
5. Define oxidation and reduction.
   Oxidation is the gain of oxygen or loss of hydrogen, while reduction is the loss of oxygen or gain of hydrogen. These reactions always occur simultaneously.
6. What is corrosion?
   Corrosion is a slow process where a metal reacts with moisture and oxygen in the environment to form a layer of oxides or hydroxides on its surface (e.g., rusting of iron).
7. What is rancidity?
   Rancidity is the process where fats and oils containing food items get oxidized, resulting in a bad smell and taste when kept open for a long time.
8. How do MCQs help in Board exam preparation?
   MCQs help students test their conceptual understanding quickly, improve time management, and are essential for the competency-based education pattern introduced by CBSE.
9. Where can I find more Chemical Reactions and Equations important questions?
   You can find more questions and notes in NCERT solutions, previous year question papers, and educational platforms dedicated to CBSE Class 10 Science.
10. What is a precipitate?
    A precipitate is an insoluble solid that forms when two aqueous solutions are mixed together, often occurring in double displacement reactions.
