NCERT Solutions for Class 10 Science, Chapter 1 - Chemical Reactions and Equations

In this chapter, you’ll study about Chemical Reactions and Equations. It is interesting to
know that we find chemical reactions everywhere around us, though we may not notice
them. Every time the food is cooked in your house, a chemical reaction occurs, and so
does it happen each time a fruit rots. A chemical reaction is a change either in the state,
colour, temperature or evolution of a gas in a substance. Some more examples of
chemical reactions are digestion of food in our body, cleaning by detergents or soaps,
iron getting rusted; burning a candle, photosynthesis and the list just goes on. In this
chapter, you will learn the basic concepts of chemical reaction, how to write chemical
reactions and balance them. Thus, in-depth knowledge of NCERT Class 10 Science,
Chapter 1 – Chemical Reactions and Equations is necessary.

Let’s take a look at topics and sub-topics of class 10 Science Chapter 1, Chemical Reactions and Equations

1.1 Chemical Equations
1.1.1 Writing a chemical equation
1.1.2 Balanced Chemical Equations
1.2 Types of chemical reactions
1.2.1 Combination Reaction
1.2.2 Decomposition Reaction
1.2.3 Displacement Reaction
1.2.4 Double Displacement Reaction
1.2.5 Oxidation and Reduction
1.3 Have you observed the effects of oxidation reactions in everyday life?
1.3.1 Corrosion
1.3.2 Rancidity

In Class 10 Science Chapter 1, you will learn – 

Section 1.1 – In this section, you’ll learn what chemical reactions are, and their
importance in our day to day lives. You’ll acquire knowledge on how to write a simple
chemical reaction and why and how to balance the equation for chemical reactions. For
instance, you’ll learn what happens when a magnesium ribbon is burnt in oxygen. You’ll
also study about reactants, products, chemical formulae, LHS and RHS of a chemical
reaction, the skeletal chemical equation, hit-and-trial method, how to write symbols of
physical state and more.

Section 1.2 – In this section, you will study different types of chemical reactions and
techniques followed such as combination reaction, decomposition reaction,
displacement reaction, double displacement reaction and oxidation and reduction.

Section 1.3 – In this section, you’ll acquire knowledge about interesting day to day
effects of chemical reactions in our everyday lives. You’ll learn about oxidation and
rancidity. Corrosion happens when the iron and other metals get rusted. Rancidity
happens when oil or fat-related food get spoiled.

In this chapter, you are provided with several activities and examples with their
solutions so that you get a clear understanding of Chemical Reactions and Equations.
