FAQs on Fun Video: Stoichiometry & Stoichiometric Calculations Video Lecture - Chemistry Class 11 - NEET

1. What is stoichiometry?
Ans. Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. It involves calculating the amount of substances involved in a chemical reaction based on the balanced chemical equation.
2. How do you calculate the stoichiometric ratios?
Ans. To calculate the stoichiometric ratios, you need to determine the balanced chemical equation for the reaction and identify the stoichiometric coefficients. These coefficients represent the number of moles of each substance involved in the reaction. The ratios can be calculated by comparing the coefficients of the reactants and products.
3. Can you explain how to perform stoichiometric calculations?
Ans. To perform stoichiometric calculations, you first need to balance the chemical equation. Then, convert the given quantity of a reactant or product to moles using its molar mass. Use the stoichiometric coefficients to relate the moles of the given substance to the moles of the desired substance. Finally, convert the moles of the desired substance back to the desired quantity (mass, volume, etc.) using its molar mass or other appropriate conversion factors.
4. What are the limitations of stoichiometry?
Ans. Stoichiometry assumes that the reaction takes place under ideal conditions and that all reactants are completely consumed to form the products. In reality, reactions may not always proceed to completion due to factors such as side reactions, impurities, and incomplete mixing. Stoichiometry also does not consider factors such as reaction kinetics, temperature, and pressure, which can affect the yield and efficiency of a reaction.
5. How does stoichiometry relate to real-life applications?
Ans. Stoichiometry is essential in various real-life applications, including pharmaceuticals, environmental chemistry, and industrial processes. It helps in determining the right amounts of reactants to use for a desired product, optimizing reaction conditions, calculating yields, and ensuring the efficient use of resources. For example, in the production of medications, stoichiometry is crucial to ensure that the correct amounts of reactants are used to obtain the desired active compounds with minimal waste.
