CBSE Class 10 Science Chapter 1 NCERT Solutions
In this initial chapter of Science of Class 10 will help the students to learn about the basics of chemicals and their respective reactions with different chemicals and compounds. The reaction between 2 chemicals is not always balanced. There is a need to balance the reactions. In this chapter, students will know about the balancing of the chemical reactions.
The chapter also deals with various types of chemical reactions like Combination reactions, Disproportion reaction, etc. This chapter plays an important role in science syllabus as the students will be able to understand the basic concepts of chemicals and their reactions which will help them to understand further topics in a better way. In this chapter, you will find a total of 20 questions with MCQs, balancing questions, short and long answer type questions, etc.
Topics Covered under NCERT Solutions for Class 10 Science Chapter 1
- Ex. 1.1: Introduction to Chemical Reactions
- Ex. 1.2: Balancing of Chemical Reactions
- Ex. 1.3: Types of Chemical Reactions
- Ex. 1.4: Corrosion and Rancidity
1.1: Introduction to Chemical Reactions
In the initial phase, the chapter talks about the introduction to chemicals and their reactions. The students will learn about how to form chemical reactions’ equations. The chapter provides step by step process to form these reactions. This basic way of teaching will help the students to build equations easily.
1.2: Balancing of Chemical Reactions
All chemicals cannot react with different chemicals without proper balancing. So, this part of the chapter will help you to balance both the sides of the chemical reaction through step by step approach.
1.3: Types of Chemical Reactions
Chemical Reactions seems to be an easy term but in practice, it is not that simple. There are various types of chemical reactions like Combination reaction, Displacement reaction, Decomposition reaction, Double Displacement Reaction, etc.
1.4: Corrosion and Rancidity
Tarnishing of a metal is known as Corrosion whereas oxidation of fats and oils is known as Rancidity. Students will come to know about the various practical life incidents where corrosion and rancidity exists.

Solved Questions For You:
Question 1. What happens when dilute hydrochloric acid is added to iron filings?
When dilute is added to iron fillings the reaction proceeds as:
Question 2. What is a balanced chemical equation? Why should chemical equations be balanced?
A balanced chemical reaction is an equation that has equal numbers of each type of atom on both sides of the arrow.
Question 3. What does one mean by exothermic and endothermic reactions? Give examples.
The chemical reactions release energy in the form of heat, light, or sound, are called exothermic reactions. An exothermic reaction occurs when the temperature of a system increases due to the evolution of heat. This heat is released into the surroundings, resulting in an overall negative quantity for the heat of reaction.
Question 4. Why is respiration considered an exothermic reaction? Explain.
