Chen and Alexander Van Buren 9/15/11 AP Chemistry Dr. Isotone Lab 1: Determination of the Empirical Formula of Silver Oxide Lab Objective: In this experiment‚ the percent composition and empirical formula of silver oxide will be determined. Silver oxide will be heated until it decomposes to silver metal and oxygen‚ and the percent calculation and empirical formula can be calculated based on combining the ratios of silver and oxygen in the reaction. Summary of Lab Procedure:

Chemistry 2 Jorge Nuñez Ms. Principe / Period 2 February 8th‚ 2011 Aim: How are we going to determine the empirical formula of a compound? Do Now: 1) What is the percent by mass of oxygen in H2C2O4? H2 = 2(1) = 2 ; C2 = 2(12) = 24 ; O4 = 4(16) = 96 Gram Formula Mass = 90 Percentage of Oxygen = 6490 x 100 = 71% 2) Calculate the percentage of water: -Mass of empty crucible and cover = 11.7g -Mass of crucible‚ cover‚ and hydrate before heating = 14.9g -Mass of crucible

Synthesis and Decomposition of Zinc Iodide Partners: Sonya Pasia and Kristen Kobayashi CH 085-01 20 September 2011 Zinc Iodide (ZnI2) was an interesting binary compound to experiment with. In this experiment‚ weakly acidified water (25mL distilled water with 18 drops 5M acetic acid solution) was used as an aid to bring molecules of the zinc and iodide atoms together‚ by dissolving iodine molecules‚ so that bonding would transpire to produce a reaction. Deprived of water‚ the Zn and I2

Tin is a chemical element with the symbol Sn from the Latin word “stannum.” Its atomic number is 50 and its atomic mass is 118.71. Tin is classified in the ’Other Metals’ section which can be located in groups 13‚ 14‚ and 15 of the Periodic Table. All of these elements are solid‚ have a relatively high density and are opaque. This silvery‚ ductile metal is not easily oxidized in air and resists corrosion. Tin is usually malleable‚ but when cooled it is very brittle. It is found in many alloys

PREPARATION OF TIN TETRAIODIDE 09/06/2012 Introduction The objective of this project was to prepare tin tetraiodide through the following reaction: Sn+2I2∆SnI4 and to measure the melting point of tin tetraiodide. Tin tetraiodide was recrystallized after the synthesis. The percent yield and the theoretical yield of tin tetraiodide were calculated. Recrystallization is to further improve the purity of tin tetraiodide. The solvent is carefully chosen to be toluene in order to maximize the recovery
