Physics forums - the fusion of science and community. Stoichiometry rests upon the very basic laws that help to understand it better, ie, law of conservation of mass, the law of definite proportions. Stoichiometry is a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data. I cant seem to figure out stoichiometry can someone give me all the steps to figuring out these problems (phosphine gas reacting with oxygen) 4ph3+8o2. Stoichiometry is a branch of organic chemistry, which helps in dealing with certain mathematical calculations and estimates it also deals with the composition.
Aluminum sulfide reacts with water to form aluminum hydroxide and hydrogen sulfide (a) write the balanced chemical equation for this reaction. Fe_2o_3 + 2al rarr 2fe + al_2o_3 + delta the stoichiometric equation is balanced as it must be, and it dictates 2:1 molar equivalence between aluminum and iron oxide. I'll assume that your question is asking what the point of stoichiometry is, rather than asking how to do it if i'm mistaken in this guess, there are a lot of good.
