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.

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…
Definition: The momentary forces of attraction which are created between and induced dipole is called Instantaneous dipole-induced dipole forces or London Dispersion Forces. Or The forces of attraction between non-polar molecules which are formed polar for an instant are called instantaneous dipole-induced dipole forces or London forces. Explanation: The forces of attraction present among the…
Introduction: In 1787, Charles found a relationship between volume and temperature of gases. He announced this relationship in the form of a law known as Charles’ law: Definition: “Volume of a given mass of a gas is directly proportional to the absolute temperature at constant pressure.” Mathematical Charles Law Formula: Another Statement for Charles’ Law:…
Diffusion of Gases: 1. The spontaneous mixing of molecules of different gases by random motion and collision until the mixture becomes homogeneous is called diffusion of gases. 2. Molecules of more than one gas are involved. 3. Molecules of lighter gases diffuse fastly. Effusion of Gases: 1. The escaping of one by one gas molecules…
The study of relationship between the amounts of reactants and products as indicated by the balanced chemical equation is called stoichiometry. Explanation: Stoichiometry is used to calculate the amount of the product formed or that of the reactant required in a reaction. Stoichiometric calculations are performed by the following assumptions in hand: Reactants are completely…
When we consider the hydrides of group VA, VIA, VIIA then NH3, HF and H2O show maximum boiling points in the respective series. The reason is the enhanced electronegative character of N, O and F. That is why, water is liquid at room temperature, but H2S and H2Se are gases. Comparatively high boiling points of…
