MOLECULAR FORMULA DEFINITION
A formula which tells the actual number of atoms present in a molecule of a substance is known as molecular formula.
Examples: H2O2 and C6H12O6 are the molecular formulas of hydrogen peroxide and glucose respectively.

Students & professionals from other sciences quite often ask the question, why is chemistry called the Central Science. Is it physics with the fundamental laws small blocks of built atoms added mass that allows the calculations to take place and prediction of the final product Or Is it chemistry that enables thought process atoms to…
A technique which is used to find out relative abundance of isotopes with respect to their atomic masses in the form of graph, is called Mass Spectrometry. Is mass spectrometry quantitative or qualitative? Mass spectrometry is used for quantitative as well as qualitative analysis. What is a mass spectrometer used for? An instrument, which…
Intermolecular Forces Definition Chemistry: The attractive forces that exist between the individual particles (molecules, atoms or ions) are called intermolecular forces. (Van der Waals’ forces). The physical state of a substance depends on the strength of intermolecular forces. The properties of liquids such as boiling point, heat of vaporization, vapour pressure, surface tension and viscosity…
Definition: The electrostatic force between a hydrogen atom bonded to a strongly electronegative atom and Hydrogen bond lone pair electrons of another Covalent bond strongly electronegative atom is called hydrogen bonding. Strength: Hydrogen bonds are not really chemical bonds in formal sense. These are weaker than covalent bond. However, hydrogen bonds are stronger than dipole-dipole…
This Law was given by Mikhail Lomonosov. This law states that “the total mass can neither be created nor destroyed but can be converted from one form to another during a chemical reaction”. Explanation: Since all the matter is composed of atoms, therefore, atoms can neither be created nor destroyed during a chemical reaction. Total…
The lower density of ice than liquid water at 0°C compels water in ponds and lakes to freeze from surface to the downward direction. Water attains the temperature of 4°C by the fall of temperature in the surrounding. As the outer atmosphere becomes further cold, the water at the surface becomes less dense. This less…
