10 Test Tube Mystery Introduction: The students were handed 10 test tubes with no identification. The students were supposed to design a method in determining what chemical was in each test tube. The list of chemicals is CuSO4‚ NH4Cl‚ NaOH‚ AgNO3‚ KI‚ H2SO4‚ NaBr‚ CaCl2‚ HCl‚ and Pb(NO3)2. The students are expected to determine the chemicals using physical properties‚ litmus paper‚ solubility‚ and the process of elimination. Physical properties‚ such as the color‚ can be determined by sight. Litmus

Discovering the Mystery of Eleven Test Tubes Karen Radakovich Ph.D. Mohammad Farhad Brittany Cina CH 223‚ Spring 08 Abstract: Eleven mystery test tubes labeled from K-1 to K-11 contained: 6M H2SO4‚ 6M NH3‚ 6M HCl‚ 6M NaOH‚ 1M NaCl‚ 1M Fe(NO3)3‚ 1M NiSO4‚ 1M AgNO3‚ 1M KSCN‚ 1M Ba(NO3)2‚ 1M Cu(NO3)2 respectively. The contents of the test tubes were determined by chemical experiments. Solution K-1 contained NiSO4 because when solution K-9‚ ammonia which was identified by its pungent odor

1. INTRODUCTION : Gas Turbine-Generator system has proximity to zero level due to absence of condenser. Therefore‚ Generator should have Terminal Bushings at the top of the Stator Frame. This avoids digging of tunnel / trench for routing Bus Duct and also avoids accumulation of gases from safety point of view. It was decided to develop a module THRI 108/44 for application with Gas Turbine. 2. DESIGN CHALLENGES : Since‚ bar type design of THRI 108/44 module for GTG application is not

EXPERIMENT ONE- BIOLOGY MODEL Answers TO DETERMINE THE EFFECT OF CHEMICALS AND TEMPERATURE ON MEMBRANE DESTRUCTION AND PERMEABILITY IN BEETROOT (Beta vulgaris) Introduction The cell membrane is made up primarily of phospholipids and proteins which contribute to its selectively permeable nature. The function and permeability of the cell membrane depends on its intact structure. When destroyed‚ the permeability of the cell membrane is disrupted causing cellular contents to leak out. The cell
