Assignment of the Day:

 * On your page, you'll need to:
 * 1) Add a horizontal rule below your Ionic vs. Covalent section by clicking on the "**//Horizontal Rule//**" buttom in the editor (see picture below).
 * 1) Add today's date and a title - "**__Guide to Naming and Wriiting Formulas for Chemical Compounds__**".
 * 2) You'll need to list the Ionic and Covalent compounds as well as the two acids you were given by the teacher.
 * 3) Under each name, write a 2-3 sentence description of how you determined the name of the compound. In your description, include:
 * Whether the compounds is **ionic**, **covalent**, or an **acid** and **//how you know//**.
 * If the compound is **__Ionic__** - what are the charges of the ions involved and **//how you know//** the charges.
 * If the compound is **__Covalent__** - what **//prefixes//** are needed/used.
 * If the compound is an __**Acid**__ - which **//rule//** did you use to determine the name/formula (State the rule from your notes). **//Explain//** how you used it.
 * 1) Add a picture of each compound to the page.

(Given) FePO4 - (Name) iron (III) phosphate
 * Since this compound includes the metal iron, it is an Ionic compound. No prefixes are needed with ionic compounds, so I simply named the two ions involved - iron (3+) and phosphate (3-). The last thing I had to do was add a roman numeral since iron is a transition metal. The charge on iron must be (3+) since the charge on phosphate is (3-).

(Given) Carbon dioxide - (Formula) CO2
 * Since both the elements in this compound are nonmetals, it is a covalent compound. The prefixes tell me how many atoms of each element are involved. There is no prefix on carbon since it is the first element in the compound, there is then 1 carbon. The prefix di- tells me there are 2 oxygen atoms in the compound.



(Given) Hydrochloric acid - (Formula) HCl
 * The prefix hydro- and suffic -ic, tell me that Rule #1 is used. When Rule #1 is used the anion involved ends in -ide. In this case it is the chloride ion (Cl-). The (-1) charge on the chloride ion is balanced by 1 hydrogen ion (H+).

Purpose

 * We'll use these pages to compile information about various topics that we cover throughout the year.
 * Everyone will be able to create their own wikipage.

Features

 * You're able to hold online discussions in the "Discussions" tab at the top of each page.
 * You're able to send each other messages by clicking on the envelope in the top right corner of the window.
