Stoichiometry review Notes Stoichiometry: Stoich. Is used to convert between compounds/elements in chemical equations. Stoich. Is based upon molar equivalencies known as mol ratios Stoich. Is used across each area of chemistry When given grams or liters always convert to mols before doing stoich. Example 1. Limiting reactants: The limiting reactant limits the amount of product produced and will always determine the theoretical yield for the reaction. The limiting reactant is often the reactant with the largest coefficient but not always! When it is not immediately clear which reactant is the limiting reactant then you have to analyze to determine the limiting reactant Example 2. Theoretical Yield, Actual Yield, and Percent Yield Theoretical yield is the quantity usually in grams defined by the stoichiometry (math you

Percent yield describes the actual percentage of the theoretical yield you were able to obtain in the lab % yield = (actual yield/theoretical yield) x 100 Net ionic equation Molecular equation is a double displacement reaction that may take place in an aqueous solution Total ionic equation is a equation which shows the states of reactants and products when they have been placed in a solvent (includes spectator ions) Net ionic equation is an equation that shows only the reactants and products which form a new substance. (no spectator ions) Remember to always write states of matter Remember to always Balance equations Remember to always use solubility rules...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
