FAQs on Balanced and Unbalanced Chemical Equations Video Lecture - Class 10

1. What is a balanced chemical equation?
Ans. A balanced chemical equation represents a chemical reaction where the number of atoms of each element is equal on both the reactant and product sides. It follows the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
2. How do you balance a chemical equation?
Ans. To balance a chemical equation, you need to adjust the coefficients in front of the reactants and products so that the number of atoms of each element is the same on both sides of the equation. You can start by balancing the elements that appear in the fewest compounds and then proceed to balance the rest.
3. What are the consequences of an unbalanced chemical equation?
Ans. An unbalanced chemical equation does not accurately represent the reactants and products involved in a chemical reaction. This can lead to incorrect predictions of the products formed or the amount of reactants required. It also violates the law of conservation of mass.
4. Why is balancing chemical equations important?
Ans. Balancing chemical equations is essential because it ensures that the atoms and mass are conserved during a chemical reaction. It allows us to accurately determine the stoichiometry of a reaction, which is crucial for understanding the relationship between reactants and products.
5. Can chemical equations be balanced without changing the subscripts?
Ans. No, chemical equations cannot be balanced by changing subscripts. Subscripts represent the number of atoms of an element in a compound, and altering them would change the identity of the compound. Balancing equations requires adjusting coefficients to maintain the same ratio of atoms on both sides of the equation.
