Foundation of Chemistry
Chapter 1 serves as the foundational chapter for the chemistry portion of the Class 10 Science syllabus. It introduces students to the fundamental concepts of chemical reactions, equations, and types of reactions.
Weightage in Exams
Questions from Chapter 1 are likely to appear in the board examinations. Understanding the content of this chapter is essential to answer questions related to chemical reactions, balancing equations, and types of reactions correctly.
This chapter lays the groundwork for understanding more advanced topics in chemistry in higher classes. Concepts like balancing chemical equations and identifying types of chemical reactions are essential for building a strong foundation in chemistry.
The concepts covered in 10th Science Chapter 1 are often used to create application-based questions in the board exams. Students may be asked to apply their knowledge of chemical reactions to real-life scenarios.
The chapter includes numerical problems related to balancing chemical equations. These problems help students develop problem-solving skills and are commonly included in the exams.
Class 10 Science Chapter 1 also introduces the concept of redox reactions (oxidation and reduction), which is a fundamental concept in chemistry. Understanding redox reactions is crucial for higher-level chemistry studies.
What is meant by a skeletal chemical equation? Using suitable chemical reaction, differentiate between a skeletal chemical equation and a balanced chemical equation.
If the number of atoms of any element in a chemical equation is not equal on both sides, then it is a skeletal equation. For example:
Here, the number of chlorine and hydrogen atoms are not equal on both sides.
In a Balance equation, the numbers of atoms of different elements on both sides of a chemical equation are equal. For example:
Important Questions on 10th Science Chapter 1
What is a balanced chemical equation? Why should chemical equations be balanced?
A reaction which has an equal number of atoms of all the elements on both sides of the chemical equation is called a balanced chemical equation. The law of conservation of mass states that mass can neither be created nor destroyed. Hence, in a chemical reaction, the total mass of reactants should be equal to the total mass of the products. It means that the total number of atoms of each element should be equal on both sides of a chemical equation. Hence, it is for this reason that chemical equations should be balanced.
Why is respiration considered an exothermic reaction? Explain.
Energy in our body is obtained from the food we eat. During digestion, large molecules of food are broken down into simpler substances such as glucose. Glucose combines with oxygen in the cells and provides energy. The special name of this combustion reaction is respiration. Since energy is released in the whole process, it is an exothermic process.
Why are decomposition reactions called the opposite of combination reactions?
Decomposition reactions are those in which a compound breaks down into two or more substances. These reactions require a source of energy to proceed. Thus, they are the exact opposite of combination reactions in which two or more substances combine to give a new substance with the release of energy.
Why do we apply paint on iron articles?
Iron articles are painted because applying paints prevents them from rusting. When painted, the contact of iron articles from moisture and air is cut off. Hence, rusting is prevented their presence is essential for rusting to take place.
Oil and fat containing food items are flushed with nitrogen. Why?
Nitrogen is an inert gas (at room temperature) and does not easily react with oil and fat containing items. On the other hand, oxygen reacts with food substances and makes them rancid. Thus, bags used in packing food items are flushed with nitrogen gas to remove oxygen inside the pack. When oxygen is not present inside the pack, rancidity of oil and fat containing food items is avoided.
Explain the following terms with examples in each case:
(i) Oxidation and (ii) Reduction.
(i) Oxidation: it us a process (a) in which oxygen or any electronegative element is added up or (b) hydrogen or any electropositive element is removed. Examples are:
(a)Sulphur burns in the air with a blue flame to form sulphur dioxide. Here oxygen is added up to sulphur.
(b) Hydrogen sulphide combines with iodine to give hydrogen iodine and sulphur.
(ii) Reduction: It is a process in which (a) Hydrogen or an electropositive element is added up.
(b) Oxygen or electronegative element is removed.
(a)Hydrogen reacts with chlorine to form hydrogen chloride.
(b)Copper oxide is reduce with hydrogen.
The chapter 1 of 10th Science include descriptions of simple experiments related to chemical reactions. Questions about experimental procedures and observations are often asked in exams to test students’ practical knowledge.
Since 10th Science Chapter 1 deals with fundamental concepts and equations, it offers good scoring potential. If students thoroughly understand the content and practice solving problems, they can score well in this chapter.
Concepts introduced in Class X Science chapter 1, such as balancing equations and identifying types of reactions, are applied in subsequent chapters of the Class 10 Science syllabus. A strong grasp of Chapter 1 is essential for success in these chapters as well.
In summary, NCERT Class 10 Science Chapter 1 is important not only for the foundational knowledge it provides but also because it sets the stage for understanding more complex chemistry concepts in higher classes. Students should give due attention to this chapter in their exam preparation to perform well in their Class 10 Science board exams.
10 Science – Chemical Reactions and Equations – Important Questions
Why is respiration considered an exothermic reaction?
During digestion, food is broken down into simpler substances. Food like rice, potato and bread are made up of carbohydrates. These carbohydrates are further broken down into glucose. Glucose during respiration (inhalation of oxygen) is oxidised with the liberation of energy as shown below. Thus, respiration is an exothermic process.
