=Naming compounds= Open the document "Naming compounds" and complete the following:

1. Use the examples in the document (don't look at any other sites/pages on this wikispace/notes/books) to come up with a set of rules for naming compounds (if you already know the rules explain them to the rest in the group). Write down the rules in your book. 2. Now test your rules by naming the compounds in the table under the heading "test your rules". 3. Use the document below to check your answers. 4. If necessary change your rules.

__Exercises:__ 1. Answer questions 1 and 2 on page 1 of the handout 1e and all questions on worksheet "Naming chemicals". 2. eChalk: play the "chemical formulae tetris game".

=Writing formulae of common compounds= On page 1 of the handout 1e complete the box "formulas of common molecules".

=Writing formulae for ionic compounds= 1. Read the "rules for writing formulae of ionic compounds" and 2. Practice: =Word equations= 1. Write word equations for the chemical equations at the bottom of page 2 in handout 1e. 2. You can also do questions 1 and 2 on the worksheet " word and symbol equations" on section d and e.
 * eChalk: do "binary ionic compounds"; you can practice both naming chemicals and writing their chemical formulae.
 * do the "examples" and "exercises" at the top of page 2 in the handout - use the table of valencies of common ions.
 * Book p

=Chemical equations= Writing a chemical equations is the same as writing a balanced symbol equation. You only need to add state symbols when asked for although it will be good practice to add state symbols when you can. 1. Read the rules on page 3 in handout 1e or page 102 in your textbook. 2. Do "balancing equations" on explorelearning. 3. Do both "balancing chemical equations" and "balancing the photosynthesis equation" on echalk. 4. Exercises 1 and 2 on page in handout 1e. 5.There are a number of interactive tutorials on the section 1 d and e page
