Some skills you should have from CH304K. These will be referred to in varying amounts during the semester so if the terms are unfamiliar or not in recent memory you should look over your CH304K notes and chapters 1-4 and 7 in your Chemistry in Context textbook to revise them. Also be aware that some issues hinted at in earlier chapters will now be elaborated upon, (such as smog) so you may want to look over the book as we get to these to refresh your memory. ELEMENTS: Be familiar with the Periodic Table. DIATOMIC / POLYATOMIC ELEMENTS: Know the elements that exist as molecules: H 2 , N 2 , O 2 , F 2 , Cl 2 , Br 2 , I 2 and, P 4 , S 8 , O 3 COMPOUNDS: Be able to distinguish and name/write formulae for: MOLECULAR COMPOUNDS - discrete molecules, e.g. carbon dioxide, CO 2 . IONIC COMPOUNDS - regularly repeating array of IONS called a crystal. e.g. sodium chloride (table salt), NaCl, iron(III)oxide (rust), Fe 2 O 3 BALANCING EQUATIONS – know how to do this.
