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.

The associate degree (AD) in Chemistry, equivalent to the European level 5, is a two-year higher professional education between the four-year MBO (level 4) and the four-year HBO bachelor (level 6). Many people think a four-year bachelor’s degree is far too long, especially if you want to do it part-time, you are vulnerable, because work,…
The pressure above the surface of the liquid by the vapours at equilibrium between liquid and its vapours at a particular temperature is called equilibrium vapour pressure or simply vapour pressure. Explanation: If we enclosed a liquid in a vessel, molecules start to evaporate above the surface of liquid. Such molecules return back to the…
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…
A reactant that controls the amount of the product formed in a chemical reaction due to its smaller amount is called limiting reactant. Excess reactant: A reactant which is present in large amount in a chemical reaction & some of its amount left after the completion of chemical reaction is called excess reactant. Explanation:…
Soaps and detergents perform the cleaning action because the polar parts of their molecules are water soluble due to hydrogen-bonding and non-polar parts remain outside water.
Definition: R.J. Clausius deduced an equation for the pressure of an ideal gas from the above assumptions of kinetic theory. This equation is called kinetic equation. Mathematical equation: Explanation: Since the molecules of a gas under the given conditions don’t have the same velocity, therefore mean square velocity is considered. If there are n1 molecules…
