Mind Map for Chapter 1 of Class 10 Science

Every Student needs a mind map to remember things easily that’s why we have created this Class 10 Science Chapter 1 Mind Map Which will help students to remember this chapter in an easy way. let’s check it

Chapter 1: Chemical Reactions and Equations Mind Map

1. Introduction

  • Definition of chemical reactions
  • Examples from daily life
  • Milk souring
  • Rusting of iron
  • Fermentation of grapes
  • Cooking food
  • Digestion
  • Respiration

2. Chemical Equations

  • Word Equations
  • Representation of chemical reactions using words
  • Example: Magnesium + Oxygen → Magnesium Oxide【6:1†source】
  • Skeletal Chemical Equations
  • Representation using chemical formulae
  • Example: Mg + O₂ → MgO【6:1†source】

3. Balancing Chemical Equations

  • Law of Conservation of Mass
  • Total mass of reactants = Total mass of products
  • Steps to Balance Equations
  1. Write the unbalanced equation
    • Example: Fe + H₂O → Fe₃O₄ + H₂【6:2†source】
  2. Count atoms of each element on both sides
  3. Use coefficients to balance each element
  4. Balance oxygen and hydrogen atoms last【6:3†source】
  5. Check the balanced equation
    • Example: 3Fe + 4H₂O → Fe₃O₄ + 4H₂【6:3†source】

4. Types of Chemical Reactions

  • Combination Reactions
  • Two or more substances combine to form a single product
  • Example: 2H₂ + O₂ → 2H₂O
  • Decomposition Reactions
  • A single substance breaks down into two or more products
  • Example: 2H₂O → 2H₂ + O₂
  • Displacement Reactions
  • One element displaces another in a compound
  • Example: Zn + H₂SO₄ → ZnSO₄ + H₂
  • Double Displacement Reactions
  • Exchange of ions between two compounds
  • Example: AgNO₃ + NaCl → AgCl + NaNO₃

5. Effects of Chemical Reactions

  • Exothermic Reactions
  • Release of heat
  • Example: Combustion reactions
  • Endothermic Reactions
  • Absorption of heat
  • Example: Photosynthesis

6. Representation of Physical States

  • Notations for physical states
  • (s) for solid
  • (l) for liquid
  • (g) for gas
  • (aq) for aqueous solution【6:3†source】

7. Reaction Conditions

  • Indicating temperature, pressure, and catalysts in equations
  • Example: CO + 2H₂ → CH₃OH (catalyst: 340 atm)【6:3†source】
