Bond enthalpyis the energy required to form or break a given bond. Its value can change between molecules, even for the same type of bond. For example, the bond energy of H2O's two O−H bonds is 464 kilojoules per mole (kJ/mol), but in methanol (CH3OH) the one O−H bond has...

Atoms or molecules can have electrical energy in the sense that the electrons can be gained or donated. Electrical energy is extremely important because the behavior of electrons determines how an atom, molecule or substance reacts. The electrical energy of molecules relates to the concept of ...

The spring constant of a molecule is directly related to its potential energy. A higher spring constant means a stiffer bond and therefore a higher potential energy, while a lower spring constant indicates a weaker bond and lower potential energy. This relationship is described by the eq...
Plus, I don’t know how to memorize formulas. For instance, memorizing sin(A+B)=AcosB+cos. Do I need just one Loci, and how do I memorize this? Of course, this is a very simple formula, but exams are coming! I need your help.”...
How to Calculate Equivalent Weight Equivalent Weight Examples Lesson Summary Frequently Asked Questions What is the equivalent weight of NaOH? To determine the equivalent weight of NaOH, first it needs to be determined what type of substance it is. NaOH is a base; therefore, the n number of ...
Each type of bond within a molecule absorbs IR at different wavelengths. So, to identify ethanol in a sample, you have to look at the wavelengths of the bonds in ethanol (C-O, O-H, C-H, C-C) and measure the absorption of IR light. The absorbed wavelengths help to identify the ...
