Presentation Transcript

  1. Chemical Formulas Chemical Reactions And The Dreaded Mole

  2. Putting Chemical Formulas Together: The Criss-Cross Sr CO3 Rb NO3 Pb Br Hg O And Naming ionic compounds: --Use of Roman Numeral for cation charge on multivalent transition metals -- Single element anions end in -ide

  3. Naming Covalent Compounds -- Use of “mono”, “di”, “tri”, “tetra”, “pent” etc. . . -- Single element anions still end in -ide CCl4 CO2 NO2 SO5 H2O N2O3

  4. Percent Composition: (Remember; “part over the whole” -- Use the molar mass of the compound as the whole -- Use the individual element molar mass as the part NH3 BaSO4

  5. Using Percents to Calculate an Empirical Formula 26.8% Cr 32.9 % O 40.3% K 51.8 % Al 48.2 % O

  6. Chemical Reactions: Types Identify 

  7. Indicators of a chemical reaction: Factors Affecting the rate of a chemical reaction:

  8. BALANCING!! -- Only change Coefficients -- Balance Polyatomic Ions as a group -- Balance Most Difficult first -- So Single Elements last FeCl3 + Ca(OH)2 Fe(OH)3 + CaCl2 Lead IV Hydroxide + Phosphoric Acid 

  9. BALANCING!! -- Only change Coefficients -- Balance Polyatomic Ions as a group -- Balance Most Difficult first -- So Single Elements last FeCl3 + Ca(OH)2 Fe(OH)3 + CaCl2
