HON CHEMISTRY: Happy Monday! Here’s your assignment for Monday. Read the instructions below very carefully!! (If you have done this assignment already, do it again – but it’s different! The practice will be very helpful for you!!)

Today you’ll practice again on http://www.sciencegeek.net, but instructions for today are different. Today you will need to write the question, and then beside it, the correct answer, and you must turn in your work on notebook paper – but you only have to do 12 chemical formulas/naming compounds correctly from each of the first three sections below and 2 empirical formulas problems from the last section. When you get the set amount done correctly in each section, you may stop and go on to the next section. Skip a line between each compound. You may write on the back.

Label each new section, and skip a line between each question.

Go to http://www.sciencegeek.net, go to Chemistry, click on NEW Review & do the following. On your notebook paper, write the question, and then beside it, the correct answer. BE SURE AND CHECK YOUR WORK. This assignment will be graded for accuracy.

1) **Unit 3: Binary Ionic Compound Formulas** (Don’t forget that you DO have to put charges for the ions in the formulas when you show your work!)

2) **Unit 3: Ionic Compounds Involving Polyatomic Ions** (Don’t forget that you DO have to put charges for the ions in the formulas when you show your work!)

3) **Unit 3: Binary Covalent Nomenclature** (Don’t forget that you DO NOT put charges for the ions in the formulas when you show your work. Prefixes are the subscripts!)

Next, go to http://www.sciencegeek.net, go to **AP Chemistry**, click on Review & do 2 problems in the following section. On your notebook paper, write the question, and then underneath it, your work and the correct answer. BE SURE AND CHECK YOUR ANSWER. This assignment will be graded for accuracy.

4) __Chapter____ 3: Stoichiometry__ – Finding Empirical Formula from Mass Percent (Be sure and include units!!)

The assignment is due at the end of the period. If you finish early, use your time to practice other things for the Chapter 7 Test!
