what are stoichiometry reaction? they are reactions that describe the relationship between reactants and products within a chemical reactions
what is stoichiometry ratio? It is a positive interger ratio that relates the number of moles of reactants and products involved in a chemical reaction
How are mole ratios used in chemical calculations? mole ratios are used to convert between moles of reactant and moles of product, between moles of reactants, or between moles of products.
where did the term stoichiometry originate from? It was derived from two greek words "stoicheion" meaning element and "metron" meaning measure
What is the stoichiometric coefficient for oxygen when the following equation is balanced using the lowest, whole-number coefficients?
_____ C H4O(l) + _____ O2(g) => _____ CO2(g) + _____ H2O(l)
3
Aluminum metal reacts with aqueous iron(II) chloride to form aqueous aluminum chloride and iron metal. What is the stoichiometric coefficient for aluminum when the chemical equation is balanced using the lowest, whole-number stoichiometric coefficients? 2
Calcium phosphate reacts with sulfuric acid to form calcium sulfate and phosphoric acid. What is the coefficient for sulfuric acid when the equation is balanced using the lowest, whole-number coefficients? 3
