What Is Stoichiometry?
Stoichiometry as defined by our textbook is “the study of the quantitative relationships among the amounts of reactants used and the amounts of products formed in a chemical reaction”. Basically, Stoichiometry is the science of counting and studying the relationship between the amounts of the reactants to the product. To think of stoichiometry outside of chemistry, imagine a bookshelf. To assemble the bookshelf you may need 3 planks of wood, 1 giant plank of wood, and 20 nails. Even though the amount of the reactants is high, the product would be only one bookshelf. Stoichiometry is basically studying the relations between the reactants (in this case the pieces) and the product (bookshelf).
As we learned in class, Stoichiometry uses a number of equations and constants. Namely, the Avogadro constant, the mole ratio in chemical equations, the percentage/actual/theoretical yields of products, percentage composition equations, and mass equations. These equations make the counting of products and reactants easier and more possible (instead of counting every single particle). Stoichiometry helps us determine how many particles of a substance are in an item by simply weighing the item and getting the substance’s molar mass. One could say stoichiometry is the art of weighing without weighing, and counting without counting. (Chapter 7 McGraw-Hill Ryerson chemistry 11 / 2011)
Stoichiometry in the Mining Industry
The uses of stoichiometric calculations are used in a variety of industries. The uses for stoichiometry ranges from medical to mining purposes. The reason why we choose to research the use of stoichiometry in this field out of all the other ones is because at first it seemed unlikely that the use of stoichiometric calculations would be used for
