DeMoivre’s Theorem is a very useful theorem in the mathematical fields of complex numbers. It allows complex numbers in polar form to be easily raised to certain powers. It states that for $x \in R$ and $n \in Z ,(\cos x+i \sin x)^{n}=\cos (n x)+i \sin (n x)$ Proof: This Read more…
Electronegativity is a measure of an atom’s ability to attract the shared pair electrons of a covalent bond towards itself. If atoms bonded together have the same electronegativity, the shared pair of electrons will be equally shared. If the electrons of a bond are more attracted to one of the atoms Read more…
The Kjeldahl method first came into existence in 1883 and was developed by a Danish chemist named Johan Kjeldahl. This method was specifically developed for determining the nitrogen contents in organic and inorganic substances. The Kjeldahl method of nitrogen analysis is the Industrial method for calculating the protein content in Read more…
