Empirical Formulas and Molecular Formulas

Earlier, chemical formulas were determined by the mass of elements that form a molecule but later, two important formulas were formulated- molecular formula and empirical formula. The empirical formula is the simplest ratio of the number of atoms in the molecule, on the other hand the molecular formula is the number of individual atoms in […]

Enthalpy of Dilution in Thermodynamics

Enthalpy of dilution refers to how much energy it takes to move one component from one place to another in an equal-pressure solution, or how much energy it takes to move one component from one place to another. In this case, the component is a pure liquid when it first comes into contact with the

Evaluated with the Help of Geometry in Three Structures

This term comes from the words “gê,” which means “earth,” and “métron,” which means “a measure.” is, along with arithmetic, one of the older subfields that fall under the umbrella of mathematics. It is concerned with the qualities of space that are related to distance, form, size, and the position of figures in relation to

Example of gases

A gas is a condition of material that has neither a definite volume nor a defined shape. In other words, a gas takes on the shape and volume of the container in which it is contained. Condensation of gases into liquids or ionization of gases into plasma. The particles in a gas are further apart

Factors Affecting Melting Point

Melting Point The melting point of a material or a compound is being used to evaluate its cleanliness or impurities. The melting temperature of a chemical compound is the point at which a chemical compound transitions from a solid to a liquid state. In the case of a solid substance, when heat is supplied gradually,

Forces Between Atoms and Molecules

An atom is the smallest particle of an element that may or may not have an independent existence but is always present in a chemical process. An atom is the smallest unit of an element that keeps its characteristics. Subatomic particles make up an atom, and they can’t be created or destroyed. Although various elements

Graham’s law

Graham’s Law, also known as Graham’s Law of Effusion, was developed by Thomas Graham in 1848 and became popular in 1849. Thomas Graham studied the effusion process and discovered an important characteristic: lighter gas molecules travel faster than heavier gas molecules. r1/r2 = √M2/M1 Where,  r1- rate effusion of gas 1 r2- rate effusion of

Gravimetric Analysis

Gravimetric analysis is a technique for determining the amount of an analyte (the ion under investigation) by measuring its mass. The mass of two substances containing the analyte is compared in gravimetric studies. Gravimetric analysis works on the idea of determining the mass of an ion in a pure compound and then using that information

How does Molar Conductivity vary with Concentration?

Certain conductivity, also known as conductivity of an electrolytic solution at a specific concentration, is the conductance produced by a unit volume of solution held between two platinum electrodes separated by a unit length and with a unit cross-section. The conductivity of a solution diminishes with dilution because the number of ions per unit volume
