FAQs on L7 : Synthesis reaction - Chemical Reaction, Science, Class 10 Video Lecture - Class 12

1. What is a synthesis reaction?
Ans. A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex substance. This reaction is also known as a composition reaction and is represented by the general equation: A + B → AB.
2. What are some examples of synthesis reactions?
Ans. Some examples of synthesis reactions include the formation of water (2H2 + O2 → 2H2O), the formation of ammonia (N2 + 3H2 → 2NH3), and the formation of table salt (Na + Cl → NaCl). These reactions involve the combination of elements or compounds to form new compounds.
3. How does a synthesis reaction occur?
Ans. A synthesis reaction occurs when the reactants have a higher potential energy than the products. This means that energy is released during the reaction, leading to the formation of new bonds and the creation of a more stable compound. Typically, synthesis reactions require an input of energy, such as heat or light, to initiate the reaction.
4. What are the characteristics of a synthesis reaction?
Ans. The characteristics of a synthesis reaction include the combination of two or more substances to form a single compound, the release of energy during the reaction, and the formation of more stable compounds. Synthesis reactions are often exothermic, meaning they release heat, and they usually require an input of energy to occur.
5. How are synthesis reactions useful in everyday life?
Ans. Synthesis reactions have various applications in everyday life. They are used in the production of many essential substances, such as medications, fertilizers, and polymers. For example, the synthesis reaction of acetylsalicylic acid (aspirin) is used to produce the common pain reliever. Additionally, synthesis reactions are utilized in the creation of building materials, dyes, and even food additives.
