THE inability to balance a chemical equation is a most common difficulty to students of chemistry. The author has attempted to remedy this very common weakness, and in addition to a concise explanation of chemical notation, including difficult cases of oxidation and reduction and ionic reactions, ...

Many modern treatments of phase separation at both the molecular level and the organismal level are based on partial differential equations, like the Cahn-Hilliard equation, that include spatial terms to describe mass transfer as well as reaction terms based on an assumed chemical potential function ...
This analysis is based upon archival data supplied by the Texas Education Agency, consisting of anonymous student-level Texas Assessment of Academic Skills (TAAS) records of every student in the tested grades between 1994 and 1999. The authors sought to determine the academic effects of retention ...

Entropy values of gaseous molecules can be taken from the standard tables in the Physical Chemistry text book, while the entropies of adsorbate and adsorption site are negligible. To be specific, the adsorption energy of the intermediates (O*, OH*, and OOH*) can be expressed as Eqs. (19)...
reference free energy surface in water, which can then be used to analyze the catalytic effect of the rest of the enzyme, apart from the groups directly involved in the chemistry. Hence, the resulting EVB model exactly reproduces the energetics of the solution reaction, as obtained by the ...
