Agre is the second of six children born in Northfield, Minnesota, to parents of Norwegian and Swedish descent. Agre is a Lutheran. [4] [5] Fascinated by international travel after a high school camping trip through the Soviet Union, Agre was an inconsistent student until he developed an interest in science from his father who was a college chemistry professor.
Valence shell electron pair repulsion (VSEPR) theory (/ ˈ v ɛ s p ər, v ə ˈ s ɛ p ər / VESP-ər, [1]: 410 və-SEP-ər [2]) is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. [3]
Case Western Reserve University's biochemistry program is jointly administered with the CWRU School of Medicine, and was ranked 14th nationally in the latest rankings by Blue Ridge Institute for Medical Research. [59] Case Western Reserve is noted (among other fields) for research in electrochemistry and electrochemical engineering.
The principle of mass action is at the heart of the transmission term of compartmental models in epidemiology, which provide a useful abstraction of disease dynamics. [29] The law of mass action formulation of the SIR model corresponds to the following "quasichemical" system of elementary reactions:
Western Reserve College may refer to either of two successor educational institutions from the Western Reserve College and Preparatory School in Hudson, Ohio: Western Reserve Academy , a private, mid-sized, coeducational boarding and day college preparatory school located in Hudson, Ohio, United States
Hofmann's 1865 stick-and-ball model of methane CH 4. The basis of this model followed the earlier 1855 suggestion by his colleague William Odling that carbon is tetravalent. Hofmann's color scheme, to note, is still used to this day: carbon = black, nitrogen = blue, oxygen = red, chlorine = green, sulfur = yellow, hydrogen = white. [14]
In chemistry, pH (/ p iː ˈ eɪ tʃ / pee-AYCH), also referred to as acidity or basicity, historically denotes "potential of hydrogen" (or "power of hydrogen"). [1] It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions.
Both Lewis and Kossel structured their bonding models on that of Abegg's rule (1904). Although there is no mathematical formula either in chemistry or quantum mechanics for the arrangement of electrons in the atom, the hydrogen atom can be described by the Schrödinger equation and the Matrix Mechanics equation both derived in 1925.
