Complete the following packet to the best of your ability. The topics in this packet are critical concepts you must be familiar with before even starting AP Chemistry. Most should be topics you covered in your previous chemistry course. Some concepts may be rusty, and some might be new altogether. If you find yourself struggling with a concept, I recommend using Kahn Academy to help you. Your completed packet is due by August 24th and should be emailed to me at: sandy.nordbrock@img.education.

Aluminum metal is reacted with aqueous hydrochloric acid to form hydrogen gas and aluminum chloride. 2. When solutions of potassium chloride and silver nitrate are reacted, silver chloride is precipitated. The other product is potassium nitrate. 3. Sodium hydroxide is neutralized by the addition of sulfuric acid; producing water and a dissolved salt, sodium sulfate. 4. Solid iron metal can be oxidized with a solution of potassium permanganate to produce iron (III) oxide, manganese (IV) oxide, and potassium oxide. Empirical and Molecular Formulas 1. A white powder is analyzed and found to contain 43.64% phosphorus and 56.36% oxygen by mass. Calculate the empirical formula. 2. A compound contains only carbon, hydrogen, and nitrogen. Combustion of 0.350g of the compound produces 0.335 g CO2 and 0.411 g H2O. Calculate the empirical formula.
