In the Indian education system of some Indian states, the Pre-University Course (PUC) or Pre-Degree Course (PDC) is referred to as intermediate or +2 course, which is a two-year senior secondary education course that succeeds the tenth grade (known as SSLC or SSC in such states, equivalent to sophomore in the US system) and precedes to the completion of a Senior Secondary Course.
Harry G. Day (October 8, 1906 – September 8, 2007 [1]) was an American chemist and professor. The Harry G. Day Lectureship in the chemistry building at Indiana University in Bloomington, Indiana, was established in 1988, and a lecture hall was dedicated to him in 1991.
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.
The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').
Among the private universities in Chattogram, Premier University is the first to receive this accreditation. [6] In 2012, this university had previously obtained permanent campus approval from the UGC. During the first years, the university offered a four-year bachelor's and two-year master's degrees in only a few subjects. [7]
Harry Gray's most significant work lies at the interface between chemistry and biology. As a pioneer of the important and thriving field of bioinorganic chemistry , he has made many key contributions, the most important of which is the development of fundamental understanding of electron transfer in biological systems, at the atomic level.
Harry R. Allcock (born 8 April 1932, Loughborough, England) [1] is Evan Pugh Professor of chemistry at Pennsylvania State University in the United States. [2] Allcock obtained his B.Sc. in 1953 and his Ph.D. in 1956, both at the University of London. He is notable for his work on the "inorganic rubbers" with a phosphorus-nitrogen backbone ...
118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).
