In the Fall of 2017‚ The Center for Success Coaching was born. Formerly aligned with YouCollege‚ the academic college for The University of Toledo’s undecided student population‚ the Success Coaches now had their own unit under The Office of The Provost. A result of the restructuring process initiated by Dr. Sharon Gaber our 17th President who upon her arrival‚ reduced the number of academic colleges from 16 to 9. In a meeting that occurred the previous spring semester with our department‚ Dr. Gaber

The road to success is not straight. There is a curve called failure‚ a loop called friends‚ caution lights called family‚ and you will have flats called jobs. However‚ if you have a spare called determination‚ an engine called perseverance‚ insurance called faith‚ and a driver called God‚ you will make it to a place called success.. Life is a challenge‚ a test all humanity should sit for. From life‚ we learn so many lessons. How to overcome our fears‚ what do we aim for‚ and how can we achieve

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
