PURPOSE
The purpose of this experiment is to produce a product using Zinc and Iodine. At the end of this experiment the understanding of the Law Conversation of Mass will be acquired as well as the ability to visually distinguish between a chemical or physical change. Further carrying out this experiment, performs the abilities to determine and calculate the limiting reactant and excess reactant, figure out the empirical formula and balanced chemical equation and lastly performs the ability to calculate the percent yield. [3]
INTRODUCTION
The determination of what is the limiting reactant and excess reactant is crucial in Chemistry; specifically when producing products. “The limiting reactant is the element that will be used up first during the reaction, while the excess reactant is the element which will have some left over.” [1] Determining the limiting reactant will aid in predicting how much product will be produced. In future experiments, determining or choosing the desired limiting reactant will also be cost effective. …show more content…
Once the chemical equation is determined, the elements present in the reaction must have their molar masses determined as well as the molar mass of the entire product. The amount in grams of the element going to be used is then multiplied by the molar mass of the product and Mol: Mol ratio. Then it is divided by the molar mass of the individual element. [1] This is applied to all the elements. The element with the lowest value is the limiting reactant and the number produced is the theoretical

Essay on Synthesis and Decomposition of Zinc Iodide

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…

Breastfeeding Vs Bottle Feeding Essay

Introduction The controversial decision between breastfeeding or formula feeding is commonly faced by mothers today. Many mothers breastfeed due to the traditional and age-old belief that breastfeeding is the natural way in which infants were intended to be fed. However, societies exponential growth in food production has led to the production of infant formulae and has left many mothers questioning to which form of feeding is truly best for their children. However, despite the abundant research…
