Melting pointe determination #01 Introduction: Objective To learn how to obtain an accurate melting point using a MELTING POINT APPARATUS‚ then use them to draw eutectic curve and determine the eutectic point. Melting point of a solid is the temperature at which the solid and its liquid form are in equilibrium‚ i.e.‚ molecules move back and forth between the two states at the same rate‚ so both phases remain present. If the temperature of a solid is measured carefully as the solid is heated

Determination of an Equilibrium Constant Abstract: In this experiment‚ two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium‚ LeChatlier’s Principle‚ Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration

Why has the number of “millionaire cities” increased more rapidly in LEDC’s than MEDC’s in recent years? A millionaire city is a city with a population of over one million people. The number of millionaire cities is higher than ever before and is continuing to increase extremely fast. Recently the percentage of people living in urban areas has surpassed the number of people living in rural areas. This is due to a large proportion of people migrating to urban areas from rural areas. This is due to
