General Chemistry B Week Two: 9/5 – 9/11 1. Stoichiometry: a. Based on the conversation of mass b. Depends on the property balanced equation i. Balance the equation: H 2 O à 2 O 2 ii. Answer: H +2O à 2H O 2 c. Rules: i. Write the complete chemical reaction ii. Count the total amount of each atom on each side a. i.e. H:2 O:2 à H:2 (4) O:1 (2) iii. balance the elemtents one at a time a. start with elements OTHER than C, O, and H b. balance C,O, and H last c. use whole number coefficiants d. i.e. 2H not 2.345H iv.
