Step-by-step answers are written by subject experts who are available 24/7. Percent composition of Zn and I % composition = (mass of element / mass compound) x 100% Empirical formula of zinc iodide for your measured masses What do the results of the decomposition of zinc iodide say about the composition of the solid product from part I of the experiment (i.e. Full Ionic Equation: Ò Ò Ò ƒ Ò Ò Ò Ò ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÿÿÿÿ ÷!

3f Introduction: Describe how this experiment relates to any two of the following concepts: law of conservation of mass, ions, percent yield, limiting reagents, stoichiometry (reactant mass versus reactant moles), chemical reaction, oxidation states. î S 0 ƒ x ÷! Would this cause the calculated mass ratio, g I/g Zn, to be higher or lower than the value predicted? Add 5 mL of methanol and swirl for 15 seconds, allow zinc to settle then pour off, 16.

Q: NaHCO3(aq) + AgNO3(aq) This is a lab question, referring to zinc and iodine reacting to form zinc iodide. 4 Determination of a Chemical Formula The Reaction of Iodine with Zinc ((use THIS for the second trial in Hess’s Law Lab)) Purpose: The purpose of this lab is to determine the balanced chemical equation for the formation of zinc iodide as well as the chemical formula of the compound from the mole ratio while trying to prove the conservation of mass. sulfur à † h Ò Ò N Ò Ò Ò Ò Ò ( ( . lithium Questions are typically answered in as fast as 30 minutes. 8x10 antimony atoms Conclusion: Discuss 2 possible sources of error. You can use the “Writing a Formal Lab Report” handout to remind you of the expectations for each section and the overall format. N What errors might have led to any violation of the Law? If these are missing you will lose points on your report! Synthesis of Zinc Iodide Jessica Edwards Chem 104 Section 30 Performed: 9/4/2007 Submitted: 9/11/2007 Abstract: The objective of the experiment was to determine the formula of zinc iodide and properly figure out the percent yield of zinc and iodine. Calculate the mass of iodine and zinc reacted and produced along with mass and mole. Swirl flask contents for 15-20 min. 2. solution will be brown when done, 11. Swirl to dry remove from heat when it appears dry and let cool for 10 to 15 minutes, 19. 5p

c. Net Ionic Equation: 3. S Would this cause the calculated mass ratio, g I/g Zn, to be higher or lower than the value predicted? a. what elements are present)? your lab report, you will use Excel to calculate the average mole ratio and the empirical formula of zinc oxide from the class data. INTRODUCTION TO ZINC: Zinc has its origin form the German word “Zin” which means Tin.Zinc is found in the group IIb in the periodic table.Zinc is a transition metal having a lustrous blue white appearance. while trying to prove the conservation of mass. From the data, it is possible to calculate the masses of zinc and iodine reacted as well as the mass of zinc iodide produced. molec...

If at the end of the reaction some of the unreacted zinc escaped from the evaporating dish, the mass of the dish plus the unreacted zinc would be lower than it should be. Due to the poor shielding effect of f-electrons, there would be lanthanide contraction. DO NOT POUR OUT THE SOLID ZINC, 15.
