(Apr 2/April 3)
OBJECTIVE(S)
E. Teach multivalent metals (limit to 4 simple metals- Cu,Fe, Sn,Pb) including writing formulas with roman numerals and the suffix “ous” and “ic”
F. Describe the oxyacids, oxyanions, specifically (NO3-,ClO3-,CO32-, SO42-PO43-)
G. Name and write formulas for some common polyatomic ionic compounds (CuSO4, CaCO3, etc.)
LESSON
D block: (1) ) Practice identifying ionic compounds from list of ingredients in children's vitamins. (2) practice naming (i) binary, monovalent ionic compounds, (ii) binary multivalent ionic compounds using Stock system, (iii) binary multivalent ionic compounds using common name system, (iv) ionic compounds with polyatomic ions.
F block: (1) Oxidation of Mg to Mg0 (demonstrating (i) chemical reactions often require initiation by adding energy and (ii) formation of ionic compounds produces large amounts of energy. (2) Practice identifying ionic compounds from list of ingredients in children's vitamins. (3) Work on H and I naming ionic compound lists; see below.
ASSIGNMENT(S):
D block: For each of the four handouts (sent in email today to each student), complete answers to problems #11-20 on each worksheet-all four of them. Please provide answers on loose lined paper at beginning of next class.
F block: Complete problems #1-20 on both the following worksheets: (1) Binary Compounds with Multivalent Cations using common (Latin root) naming method. (2) Ionic compounds with polyatomic ions. Both due next class.
