Conclusion 1. Explain how the observations that were made were indicative of a chemical reaction. 2. Which of the two reactants the limiting reactant. Explain your choice. 3. Is the Law of Conservation of Mass always obeyed? What experimental errors would lead to greater mass of products than reactants? What experimental errors would lead to the mass of products being less than the reactants? 4. As part of your data analysis, you calculated the experimental empirical formula of the compound made in this lab. Was the empirical formula what you expected? Explain your answer. 5. During this experiment, some unreacted zinc may have been lost in decanting. How would this affect the ratio of moles (think carefully about this)? How would spilling zine during the decanting process affect the result for the Law of Conservation of Mass? Messs and or disonsumiacd work will not be graded. Calculate the following. Show all work and cincle your answer for each calculation. 1. Cakeulate the mass of iodine that reacted. mass of iodine = mass befor transtee massacter transter =12.7879.437=3.350sI 2.
