Stoichiometry involves calculating reactants and products in a reaction from "summary" of NCERT Chemistry Class 11 - [CBSE Board] by Dr. S. C. Rastogi, ,Er. Meera Goyal
Stoichiometry is a fundamental concept in chemistry that deals with the quantitative relationships between reactants and products in a chemical reaction. It allows us to predict the amount of products that will be formed in a reaction based on the amount of reactants used, and vice versa. By understanding stoichiometry, we can determine the ideal conditions for a reaction and maximize the yield of products. To calculate the quantities of reactants and products in a reaction, we need to use the balanced chemical equation. The coefficients in the balanced equation represent the mole ratios of the reactants and products. These ratios are crucial for determining how much of each substance is involved in the reaction. Stoichiometry can be applied to various types of reactions, including synthesis, decomposition, single replacement, double replacement, and combustion reactions. Each type of reaction follows specific stoichiometric principles that govern the amount of reactants needed and the amount of products formed. In stoichiometry calculations, we often use the concept of the mole. The mole is a unit of measurement that represents a specific number of particles (6.022 x 10^23) of a substance. By converting the mass of a substance to moles, we can easily determine the amount of that substance involved in a reaction. Furthermore, stoichiometry calculations also involve the use of molar mass. Molar mass is the mass of one mole of a substance and is expressed in grams per mole. By knowing the molar mass of the reactants and products, we can convert between mass and moles in stoichiometry calculations.- Stoichiometry is a crucial tool in chemistry that allows us to quantitatively analyze chemical reactions. By understanding the principles of stoichiometry and applying them to reactions, we can make accurate predictions about the amounts of reactants and products involved in a reaction, ultimately leading to a better understanding of chemical processes.
