3.4 Part F – The Reaction of Iron Nails with a Copper Solution Introduction: The experiment in this activity involves the reaction between a copper (II) chloride solution with iron nails and the mole ratios involved in the reaction. Measurements are taken to determine the moles of each reactant involved in the reaction and thus the number of atoms or molecules involved. Apparatus and Materials: Refer to the reaction of iron nails with a copper solution assignment in Module 3‚ Section assignment

and Processing Raw data Table of raw data Qualitative observation: At the start of the experiment‚ the crystals were blue. During the heating‚ the crystals turned white which means that they lost their water molecules. The source of hydrated copper sulphate consists of both small grains and large grains of the salt. Therefore during the heating process‚ the smaller grains of the hydrated salt turned from blue to white in just 1 minute. In other words‚ there is an uneven heat distribution‚ which

claims made by the US government‚ regarding the spectrophotometric analysis of a copper penny hold true. Before 1982‚ the Lincoln cent contained 95% copper and 5% various mixtures of zinc and tin. As the cost of copper increased‚ the cost to produce the penny was more than the actual face value of the penny. This caused the US government to change the composition of the penny. The pennies we know today consist of a copper coating‚ which contains mostly zinc metal‚ and has a 2.5% mass. The contents

With more and more studies though it’s been hard to find evidence proving these ideas. “When a muscle is lengthening‚ the muscle fibers and connective tissues are elongated because of the application of external forces.” (Pornratshanee‚ Hume‚ Kolt). When these fibers are extended it allows the muscle to experience a fuller range of motion. There
