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

 

NCERT Solutions for Class 10 Science Chapter 1 Chemical Reactions and Equations: A complete chemical equation represents the reactants, products and their physical states symbolically. In Chemical Reactions and Equations chapter you will study about the chemical equation is balanced so that the numbers of atoms of each type involved in a chemical reaction are the same on the reactant and product sides of the equation. Equations must always be balanced. In a combination reaction, two or more substances combine to form a new single substance. Decomposition reactions are opposite to combination reactions. In a decomposition reaction, a single substance decomposes to give two or more substances. Reactions in which heat is given out along with the products are called exothermic reactions. 

Here are the important topics of NCERT 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 NCERT Class 10 Science Chapter 1 Chemical Reactions and Equations, you will also study those reactions in which energy is absorbed and they are known as endothermic reactions. When an element displaces another element from its compound, a displacement reaction occurs. Two different atoms or groups of atoms (ions) are exchanged in double displacement reactions. Precipitation reactions produce insoluble salts. Reactions also involve the gain or loss of oxygen or hydrogen by substances. Oxidation is the gain of oxygen or loss of hydrogen. The reduction is basically the loss of oxygen or gain of hydrogen.

After going through this chapter line by line you must be able to solve these NCERT questions Chapter 1 Chemical Reactions and Equations which are given below:

Q1. Write one equation each for decomposition reactions where energy is supplied in the form of heat, light or electricity.

Q2. What is the difference between displacement and double displacement reactions? Write equations for these reactions.

Q3. In the refining of silver, the recovery of silver from silver nitrate solution involved displacement by copper metal. Write down the reaction involved.

If you have any doubt in solving these questions then don't worry, NCERT Solutions will help you out in getting answers to these questions. 

Try to solve all the given questions in this chapter, if you need any help then, NCERT Solutions for Class 10 Science Chapter 1 Chemical Reactions and Equations is there for you.
