Stoichiometry is the study of quantitative relationships between substances involved in chemical changes. That the Universe is a constantly changing place is readily apparent from any walk down the street. People and cars pass by, the sky is filled...

That chemical elements are made of atoms (the smallest piece of matter that still retained the chemical features of the element) was an idea first put forth by Greek philosophers. Revitalization of the atomic theory was, in part, credited to John...

(from Greek, stoicheion: an element) A branch of chemistry of interest to pharmacologists, including those interested in NEUROPHARMACOLOGY: stochiometry is concerned with determining the quantities of chemicals that react together: how much of this...

Stoichiometry (sometimes called reaction stoichiometry to distinguish it from composition stoichiometry) is the calculation of quantitative (measurable) relationships of the reactants and products in chemical reactions (chemical...

ABSTRACT The combustion of blends of R-152a and nonflammable fluoroethanes (R-134a, R-125, and R-116) was investigated by means of combustion product analysis and burning velocity measurement. Combustion reactions were carried out in a closed vessel for a variety of blend compositions and...

Fishes are important pools of nitrogen (N) and phosphorus (P), and they have important direct and indirect effects on cycling of these potentially limiting nutrients in lakes. We used a model of fish bioenergetics coupled to a mass balance model of fish N and...
