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.

Definition: The spontaneous escaping of molecules of a liquid from their surface at any temperature is called evaporation. Evaporation Process: Most common question in this regard is, How does evaporation work? All the liquid molecules do not contain the same kinetic energies. Speed of molecules depends upon kinetic energy. Molecules with high kinetic energy move…
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,…
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…
The general gas equation is not applicable to real gases at the all the temperature .and pressure. In order to make it applicable to real gases Van der Waals’ made correction in volume and pressure of the gases and derived an equation known as Van der Waals’ equation. Volume Correction The actual volume of gas…
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…
The stock system in chemistry is used for naming ionic compounds. There are some metals, which actually have more than one possible oxidation state. The stock system let us know which version of that metal ion we are considering. For example, copper can be either from a Cu+1 or Cu+2. Similarly, iron can form Fe+2…
