FAQs on NCERT Solutions for Class 10 Science Chapter 1 - Chemical Reactions and Equations
1. Before burning a magnesium ribbon in the air, why should it be cleaned
Magnesium ribbon must be cleaned before burning in the air, so as to remove the layer of MgO formed due to the reaction between magnesium and air.
2. Why not immediately a wall acquires a white colour when a coating of slaked lime is applied to it?
When a solution of slaked lime is applied on the wall, CO2 gas present in the air slowly reacts with a thin layer of calcium hydroxide to form a thin layer of calcium carbonate, that is quite white. Therefore, the newly formed calcium carbonate impart a white look to the walls.
Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l)
3. Consider the following reaction:
2FeSO4 (s) → Fe2O3 (s) + SO2 (g) + SO3 (g)
Is it a redox reaction or not? If yes, why?
It is a redox reaction because ferrous (Fe3+) whereas SO2-4 is getting reduced to SO2.
4. Identify the oxidizing agent in the following equation.
MnO2 (s) + 4HCL à MnCl2 (aq) + Cl2 (g) + 2H2O
MnO2 is the oxidizing agent in the equation.
5. Why should students refer to NCERT Solutions provided by Vedantu?
NCERT Solutions provided by Vedantu is very comprehensive and developed in a step-by-step method that makes it self-explanatory.

6. What is the chemical reaction and equations?
A chemical reaction is a process in which one or more substances react with one another and form a different substance known as a product. The product will usually have different physical and chemical properties compared to the reactants. An equation is a symbolic representation of this reaction using formulae, where reactants are on the left hand side and products on the right hand side.
7. What is a balanced chemical equation? Why should chemical equations be balanced?
A chemical equation is a symbolic representation of the entire chemical reaction. It consists of a left-hand side with all the reactants and a right hand side with the products. According to the law of conservation of mass, atoms can neither be created nor destroyed. To follow this universal law, the equation should be balanced so that the total atoms on the left side are equal to the atoms on the right side.
8. What is Chapter 1 of Class 10 Science?

14. What are four types of chemical reactions according to NCERT Solutions Class 10 Science?
The four types of Chemical Reactions are:
Combination Reactions: Reactions where two or more substances combine to form a single product.
Decomposition Reactions: Reactions where a single compound breaks down into two or more simpler substances.
Displacement Reactions: Reactions where an element displaces another element from its compound. This includes:
Single Displacement Reactions: A more reactive element displaces a less reactive element from its compound.
Double Displacement Reactions: The ions of two compounds exchange places in an aqueous solution to form two new compounds.
Oxidation and Reduction Reactions: Understanding redox reactions, where oxidation involves electrons' loss and reduction involves electrons' gain.
