What is Stoichiometry Class 11?

Hint:Stoichiometry is the measure of the amounts of reactants and products which take part in a chemical reaction or is formed. It is the relative amount of reactant and product.

What is stoichiometry in chemistry class 11?

Chemical Stoichiometry refers to the quantitative study of the reactants and products involved in a chemical reaction. The word “ stoichiometry” is derived from the Greek word “stoikhein” meaning element and “metron” meaning measure.

What is stoichiometry in simple words?

Definition of stoichiometry

1 : a branch of chemistry that deals with the application of the laws of definite proportions and of the conservation of mass and energy to chemical activity. 2a : the quantitative relationship between constituents in a chemical substance.

What is stoichiometry and example?

Stoichiometry is often used to balance chemical equations (reaction stoichiometry). For example, the two diatomic gases, hydrogen and oxygen, can combine to form a liquid, water, in an exothermic reaction, as described by the following equation: 2 H. ₂ + O. ₂ → 2 H.

What is stoichiometry BYJU's?

Stoichiometry is an integral part of chemistry that involves the relationship between product and reactants in a chemical reaction and other words, stoichiometry means the measurement of elements.

Stoichiometry - Some Basic Concepts Of Chemistry | Class 11/12/JEE/IIT/NEET

What is stoichiometry in analytical chemistry?

Stoichiometry is the quantitative relationship among the amounts of reacting chemical species. The stoichiometry of a reaction is the relationship among the number of moles of reactants and products as represented by a balanced chemical equation.

What is stoichiometry of a reaction?

Stoichiometry is a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data. In Greek, stoikhein means element and metron means measure, so stoichiometry literally translated means the measure of elements.

Who defined stoichiometry?

What Is Stoichiometry? Jeremias Benjaim Richter defined stoichiometry in 1792 as the science of measuring quantities or mass ratios of chemical elements. You might be given a chemical equation and the mass of one reactant or product and asked to determine the quantity of another reactant or product in the equation.

What is stoichiometry summary?

Stoichiometry is exactly that. It is the quantitative relation between the number of moles (and therefore mass) of various products and reactants in a chemical reaction. Chemical reactions must be balanced, or in other words, must have the same number of various atoms in the products as in the reactants.

What is stoichiometry Toppr?

What is Stoichiometry? The branch of stoichiometry deals with the calculation of various quantities of reactants or products of a chemical reaction.

Why is stoichiometry important in chemistry?

Given a chemical reaction, stoichiometry tells us what quantity of each reactant we need in order to get enough of our desired product. Because of its real-life applications in chemical engineering as well as research, stoichiometry is one of the most important and fundamental topics in chemistry.

Where is stoichiometry used?

Using the same concept of mole ratios as explained above, stoichiometry is used to figure out how much reactant is needed to make a desired quantity of product in a laboratory or manufacturing facility.

Is stoichiometry and mole concept same?

A balanced chemical reaction gives equivalences in moles that allow stoichiometry calculations to be performed. Mole quantities of one substance can be related to mass quantities using a balanced chemical equation. Mass quantities of one substance can be related to mass quantities using a balanced chemical equation.

What is stoichiometry article?

In a more usual usage, the term stoichiometry refers to the relationships between the measured quantities of substances or of energy involved in a chemical reaction; the calculations of these quantities include the assumption of the validity of the laws of definite proportions and of conservation of matter and energy.

Who discovered stoichiometry?

Stoichiometry was first discovered by Jeremias Richter, a German chemist. It was Richter who coined the term stoichiometry, a tongue-twisting word that baffles students to this day. Stoichiometry was derived from stoikheion, Greek for "element", and "metron", meaning measure.

What is stoichiometric and non stoichiometric?

Stoichiometric defects are those that do not disturb the stoichiometry of a compound. Nonstoichiometric defects are defects in crystal structures that disturb the stoichiometry of the crystal. Effect on Stoichiometry. They do not affect the stoichiometry of the compound. They change the stoichiometry of the compound.

How do you introduce stoichiometry?

Start simply by asking how many moles of reactant there are if given a particular mass of that reactant. Then determine moles of a product formed from that much reactant based on the balanced equation (I usually use a mass that gives a simple, but fractional number of moles such as 0.2, 0.4, etc.).

What is meant by mole?

A mole is defined as 6.02214076 × 10²³ of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

What is mole concept?

A mole is a unit of measurement used to measure the amount of any fundamental entity (atoms, molecules, ions) present in the substance. A mole is very much similar to the concept of weight, as both help in understanding the amount of a substance present.

What is mole in chemistry class 11?

A mole can be defined as the amount of substance that contains the same number of chemical entities (atoms, ions, molecules, etc.) as there are in 12 g of Carbon-12 isotope, as defined by the General Conference on Weights and Measures.

What are the types of stoichiometry?

What is stoichiometry by Shaalaa?

Solution. The study of quantitative relations between the amount of reactants and/or products is called stoichiometry. Concept: Chemical Reactions and Stoichiometric Calculations.

What is stoichiometric number?

For the reactants the Stoichiometric numbers are the negatives of the numbers appearing in the equation; for example the Stoichiometric number ν_A for the reactant A is -a. In other words, the Stoichiometric numbers are positive for products and negative for reactants.

What is stoichiometry PPT?

Stoichiometry deals with the numerical relationships of elements and compounds and the mathematical proportions of reactants and products in chemical transformations.
