CBSE Class 10 Science Notes Chapter 1: As you gear up for your Class 10 Science board
exams, it is only natural to feel overwhelmed looking at the vast syllabus that you need to
cover and retain. With numerous complex concepts to memorize in Biology, Physics and
Chemistry, it is easy to fall behind or feel lost.
However, it does not have to be that way. In this blog post, we break down Chapter 1 of
your Science textbook into easy to understand and digestible notes. Our simplified notes
on Chemical Reactions and Equations aim to remove any confusion you might have
regarding concepts like types of reactions, balancing equations and more.
Reading through our clear and coherent explanation of key topics should help you grasp
even difficult concepts with minimal effort. So take a deep breath, and get started on
annotating these focused chapter notes. When exam day arrives, you will thank yourself
for putting in the work now to build a strong foundation early.
CBSE Class 10 Science Notes Chapter 1 Overview
CBSE Class 10 Science can often seem daunting with its dense chapters packed with new
concepts. However, breaking down each topic into easy-to-digest points is key to making
the subject feel approachable. We aim to do just that by providing simple yet
comprehensive notes on Chapter 1 of the CBSE Class 10 Science syllabus.
Our goal here is to take this potentially complex chapter covering Chemical Reactions and
Equations and distill it down to its key essence in a manner that promotes understanding.
We will unpack the concepts step-by-step, relate them to real-world examples wherever
possible, and emphasize visual representations to complement the written explanations.
CBSE Class 10 Science Notes Chapter 1 Chemical Reaction and
Equation Notes
Below are some notes on CBSE Class 10 Science, Chapter 1: "Chemical Reactions and
Equations."
Chemical Reactions and Equations
1. Introduction:
, ● A chemical reaction involves the transformation of one or more substances into
new substances.
● The substances before the reaction are called reactants, and the substances formed
after the reaction are called products.
2. Chemical Equations:
● A chemical equation is a symbolic representation of a chemical reaction.
● Reactants are written on the left side, and products are written on the right side of
the arrow.
● Example: 2H2+O2→2H2O
3. Balancing of Chemical Equations:
● The number of atoms of each element must be the same on both sides of the
equation.
● Coefficients are used to balance equations, but subscripts cannot be changed.
● Example: CH4+2O2→CO2+2H2O
4. Types of Chemical Reactions:
● Combination Reactions:
● Two or more substances combine to form a new substance.
● Example: A+B→AB
● Decomposition Reactions:
● A single substance breaks down into two or more simpler substances.
● Example: AB→A+B
● Displacement Reactions:
● One element is replaced by another element in a compound.
● Example: A+BC→AC+B
● Redox Reactions:
● Involves both oxidation (loss of electrons) and reduction (gain of electrons).
● Example: Zn+2HCl→ZnCl2+H2
● Double Displacement Reactions:
● Exchange of ions between two compounds.
● Example: AB+CD→AD+CB
5. Effects of Chemical Reactions:
● Evolution of Gas:
● Production of gas during a reaction.
● Example: Zn+2HCl→ZnCl2+H2
● Formation of Precipitate:
● Insoluble solid formed during a reaction.
