FAQs on Detailed Explanation: Chemical Reaction & Equations Video Lecture - Science Class 10

1. What is a chemical reaction?
Ans. A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. During this process, chemical bonds between atoms are broken and new ones are formed, resulting in the creation of new substances.
2. What is a chemical equation?
Ans. A chemical equation is a symbolic representation of a chemical reaction that shows the reactants on the left side and the products on the right side. The reactants are the starting materials, while the products are the substances that are formed as a result of the reaction.
3. What are the different types of chemical reactions?
Ans. There are several types of chemical reactions, including: - Combination reactions - Decomposition reactions - Displacement reactions - Redox reactions
4. What is the law of conservation of mass?
Ans. The law of conservation of mass states that in a closed system, mass cannot be created or destroyed. This means that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.
5. How do you balance a chemical equation?
Ans. To balance a chemical equation, you need to make sure that the number of atoms of each element is the same on both sides of the equation. This is done by adjusting the coefficients in front of the reactants and products until the number of atoms of each element is balanced.
