She has contributed to the use of biochar as a green material for use in various chemical processes, [1] [2] including collaboration with Professor Francesca M. Kerton. In 2021, she was elected as the Director for Equity, Diversity, and Inclusion for the Canadian Society for Chemistry . [ 3 ]
2023: OCR was criticised by pupils and teachers for the level of difficulty in Paper 2 of the Computer Science GCSE. [22] [23] Students took to social media to express concern at the disparity between Paper 1 and Paper 2, as well as the change in style of the paper. OCR assured students that the final mark scheme would reflect the different ...
As with CIN, CAPE is usually expressed in J/kg but may also be expressed as m 2 /s 2, as the values are equivalent. In fact, CAPE is sometimes referred to as positive buoyant energy ( PBE ). This type of CAPE is the maximum energy available to an ascending parcel and to moist convection.
The University of Cape Coast was established in October 1962 as a university college and placed in a special relationship with the University of Ghana, Legon.On 1 October 1971, the college attained the status of a full and independent University, with the authority to confer its own degrees, diplomas and certificates by an Act of Parliament.
The O grade was equivalent to a GCE Ordinary Level pass which indicated a performance equivalent to the lowest pass grade at Ordinary Level.. Over time, the validity of this system was questioned because, rather than reflecting a standard, norm referencing simply maintained a specific proportion of candidates at each grade, which in small cohorts was subject to statistical fluctuations in ...
For example, sulfuric acid (H 2 SO 4) is a diprotic acid. Since only 0.5 mol of H 2 SO 4 are needed to neutralize 1 mol of OH −, the equivalence factor is: f eq (H 2 SO 4) = 0.5. If the concentration of a sulfuric acid solution is c(H 2 SO 4) = 1 mol/L, then its normality is 2 N. It can also be called a "2 normal" solution.
For example, the mass of water might be written in subscripts as m H 2 O, m water, m aq, m w (if clear from context) etc., or simply as m(H 2 O). Another example could be the electronegativity of the fluorine -fluorine covalent bond , which might be written with subscripts χ F-F , χ FF or χ F-F etc., or brackets χ (F-F), χ (FF) etc.
Quantities, Units and Symbols in Physical Chemistry, also known as the Green Book, is a compilation of terms and symbols widely used in the field of physical chemistry. It also includes a table of physical constants , tables listing the properties of elementary particles , chemical elements , and nuclides , and information about conversion ...
