DATE PERFORMED: JULY 20‚ 2007 SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT FOR A REACTION ABSTRACT UV-VIS spectrophotometry is one of the most widely-used methods for determining and identifying many inorganic species. During this experiment‚ this spectrophotometry was used to determine the equilibrium constant‚ Keq‚ of the Fe3+(aq)+SCN-(aq)↔ FeSCN2+(aq) reaction. By determining the amount of light absorbed‚ the concentration of the colored FeSCN2+ solution was also quantitatively

2.4 Numbered Heads Together (NHT) 2.4.1 The Definition of Numbered Heads Together (NHT) Numbered heads together (NHT) is one of cooperative learning technique that holds each student accountable to learn the material. Students are placed in groups and each person is given a number (from one to the maximum number in each group). They should work together to figure out the answer of problems which are given by the teacher and ensures that each member knows the answer to problems or questions. The
