Unit 8: Stoichiometry Name: _______________________ What can we do with stoichiometry? For generic equation: R A + R B P 1 + P 2 Given the… …one can find the… amount of R A (or R B ) amount of R B (or R A ) that is needed to react with it amount of R A or R B amount of P 1 or P 2 that will be produced amount of P 1 or P 2 you need to produce amount of R A and/or R B you must use Governing Equation: 2 patties + 3 bread 1 Big Mac® 4 patties + ? excess + 18 bread ? ? + ? 25 Big Macs® 1

EX. __TiO 2 + __Cl 2 + __C __TiCl 4 + __CO 2 + __CO How many mol chlorine will react with 4.55 mol carbon? What mass titanium (IV) oxide will react with 4.55 mol carbon? How many molecules titanium (IV) chloride can be made from 115 g titanium (IV) oxide? Island Diagram helpful reminders: 1. Use coefficients from the equation only when crossing the middle bridge. The other six bridges always have “1 mol” before a substance’s formula. 2. The middle bridge conversion factor is the only one that has two different substances in it. The conversion factors for the other six bridges have the same substance in both the numerator and denominator. 2
