Kemtec Science: Stoichiometry

Kemtec Science: Stoichiometry Target Grades: 9-12 Number of Students:‚ ‚ 24 students working in six groups of four Explore the types of chemical reactions, mole ratios, and stoichiometric equivalents which are central to all chemical calculations. Students perform a series of experiments including an electrochemistry decomposition reaction, single replacement reactions, and double replacement reactions. Students are encouraged to predict possible products, as well as write and balance equations representing the reactions. Students will discover the quantitative nature of chemical equations and the experimental basis of numerically balancing coefficients. Includes a lab quiz. ‚ Kit includes all required chemicals and supplies for performing experiments on a microscale. Kit contains lead nitrate.‚  Kit Contains: Instructor Manual Student Manuals MSDS Lab Quiz Sheets Toothpicks Pipettes Pencil Lead Forceps Empty Bottles with Caps Cotton String Microplates (24 Well) Microplates (96 Well) Copper Nitrate Nickel Nitrate Lead Nitrate Cobalt Nitrate Nitric Acid Aluminum Nitrate Iron Nitrate Sodium Carbonate Sodium Sulfate Sodium Chloride EDTA Sodium Iodide Sodium Thiocyanate Sodium Chromate Sodium Dichromate Sodium Hydroxide Calcium Nitrate Sodium Oxalate Copper Sulfate Hydrochloric Acid Nitric Acid Sulfuric Acid Required But Not Included: 9V Batteries with Clips and Leads
