Chemical Reaction Stoichiometry Web Site Home Page. The ChemCollective: Stoichiometry Tutorial - Reaction Stoichiometry. Reaction stoichiometry allows us to determine the amount of substance that is consumed or produced by a reaction.
The following video considers the first part of this: how much of a reactant is consumed in a chemical reaction. Product formation is discussed elsewhere. Reaction Stochiometry Movie Text Stoichiometry was first discovered by Jeremias Richter, a German chemist. It was Richter who coined the term stoichiometry, a tongue-twisting word that baffles students to this day. What Richter discovered was that it was possible to quantify the amount of substances consumed or produced by a chemical reaction.
In other words, If I had 1000 grams of sulfuric acid - a kilogram - it would take 615 grams of magnesium oxide to neutralize it. So how do we think about this in modern terms? MgO + H2SO4 → MgSO4 + H2O One molecule MgO : One molecule H2SO4 Richter's discovery of specific proportions is a consequence of this one to one reaction. Pb(NO3)2 + 2 NaI → PbI2 + 2 NaNO3.

Luigi Aloisio Galvani (Latin: Aloysius Galvani) (September 9, 1737 – December 4, 1798) was an Italian physician, physicist and philosopher who had also studied medicine and had practiced as a doctor, who lived and died in Bologna.
In 1780, he discovered that the muscles of dead frogs legs twitched when struck by a spark.:67-71 This was one of the first forays into the study of bioelectricity, a field that still today studies the electrical patterns and signals of the nervous system. Early life Luigi Galvani was born to Domenicoo and Barbara Foschi in Bologna, Italy. His father was a goldsmith and his mother was Domenico's fourth wife.
His family was not aristocratic, but they could afford to send at least one of their sons to study at a university. Another discipline Galvani learned alongside of medicine was surgery. In 1759, Galvani graduated with degrees in medicine and philosophy. As a "Benedectine member" of the Academy of Sciences, Galvani had specific responsibilities. ChemReview.NET.
