Focka 1Liz Audrey FockaProfessor PeacyCHEM 1211-004September 13 , 2018Experiment #3Purpose;To observe a demonstration of oxidation of a metal, of sublimation and deposition and toobserve the appearance of several elements Equally to determine the boiling point ofmethyl alcohol and an unknown liquid, whether a solid and a liquid are soluble orinsoluble in water and to determine whether a substance is undergoing a physical orchemical change and finally to gain proficiency in determining a boiling point.Procedure;Heating a copper wire;-Hold a copper wire with crucible tongs and heat until the wire is red hot and allow itto cool. Classify if it is a physical change.Heating Iodine Crystals;-Put 3 small crystals of iodine in a dry 250-mL beaker. Cover the beaker usingevaporating dish containing ice. Support the beaker on a ring stand and gently heatthe crystals until all iodine vaporizes. Using crucible tongs to hold the evaporating=gdish and classify whether it is a physical or chemical change.
