A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
Shrine to Oshun in the Osun-Osogbo Sacred Grove. Oshun (also Ọṣun, Ochún, and Oxúm) is the Yoruba orisha associated with love, sexuality, fertility, femininity, water, destiny, divination, purity, and beauty, and the Osun River, and of wealth and prosperity in Voodoo. [1] [2] [3] She is considered the most popular and venerated of the 401 ...
Ori literally means the head, but in spiritual matters, it is taken to mean a portion of the soul that determines personal destiny. [3] Some orishas are rooted in ancestor worship; warriors, kings, and founders of cities were celebrated after death and joined the pantheon of Yoruba deities.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
A corollary of Kasha's rule is the Vavilov rule, which states that the quantum yield of luminescence is generally independent of the excitation wavelength. [4] [7] This can be understood as a consequence of the tendency – implied by Kasha's rule – for molecules in upper states to relax to the lowest excited state non-radiatively.
The relative stability of reactant and product does not define the feasibility of any reaction all by itself. For any reaction to proceed, the starting material must have enough energy to cross over an energy barrier. This energy barrier is known as activation energy (∆G ≠) and the rate of reaction is dependent on the height of this barrier ...
Obatala is therefore the equivalent of God in the catholic syncretism who also does not have a specific sex. [9] Unlike other Orisha, Obatala only accepts offerings cooked in honey, as he has a distaste for dende oil. [9] Like any other Orisha, Obatala does not specifically eat the offering himself, but consumes the energy of the offering, or ...
A metastable state of weaker bond (1), a transitional "saddle" configuration (2) and a stable state of stronger bond (3). In chemistry and physics, metastability is an intermediate energetic state within a dynamical system other than the system's state of least energy.
