  2. BEGINNING OF CHEMISTRY

  3. Problem 128 TOPIC: Chemistry (pg 33-39) Periodic Table Categorizations of Elements • Metalloids: boron (B), silicon (S), arsenic (As), germanium (Ge), antimony (Sb), tellurium (Te), and polonium (Po) • Metals: everything to the left of the metalloids • Nonmetals: everything that is not a metal • Noble or inert gases: column on the right • Halogens: column next to noble gases What is the atomic number> What is the atomic mass? Are the electrons equal to neutrons? protons?

  4. Problem 129 TOPIC: Chemistry (pg 33-39) Oxidation (Valence) State Oxidation Number (oxidation state) • An electrical charge assigned by a set of prescribed rules. Elements have valence shells • Noble gases: completely filled shells (stable) • Non-noble elements: achieve a more stable shell by adding/losing electrons How does sodium reach a stable state with filled shells? How does oxygen reach a stable state with filled shells? How does aluminum reach a stable state with filled shells? How is Manganese different than (a) through (c)

  5. Problem 130 TOPIC: Chemistry (pg 33-39) Nitrogen (N) the most notable exception, can have any valence in its row (+5 to –3, but never zero). Since nitrogen is diatomic (N2): how does it become stable? Some valence states to remember are: • hydrogen (H) column: +1 • beryllium (Be) column: +2 • boron (B) column: +3 • fluorine (F): –1 • oxygen (O): –2 Ionic compounds are based on the unequal sharing of electrons Covalent compounds are based on the sharing of electrons to become stable (b) How is methane (CH4) bonded?

  6. Problem 131 TOPIC: Chemistry (pg 33-39) (a) (b) The valence (oxidation state) of manganese in potassium permanganate, KMnO4 is:

  7. Problem 132 TOPIC: Chemistry (pg 33-39) (a) Calculate the total number of mols in the following mixture of gases: H2 20 g CH4 30 g C3H6 25 g (b) Calculate the mol fractions of the compounds in the mixture above

  8. Problem 133 TOPIC: Chemistry (pg 33-39) (a) Calculate the total number of mols in the following mixture of gases: H2 20 g CH4 30 g C3H6 25 g (b) Calculate the mol fractions of the compounds in the mixture above
