Experiment 7: A Study of Chemical Changes: Types of Chemical Reaction INTRODUCTION Chemical changes are results of chemical reactions. All chemical reactions involve a change in substance and a change in energy. They are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. There are different types of chemical reaction classified into 4 general types‚ namely‚ Synthesis‚ Decomposition

“I believe that everything happens for a reason. People change so that you can learn to let go‚ things go wrong so that you appreciate them when they’re right‚ you believe lies so you eventually learn to trust no one but yourself‚ and sometimes good things fall apart so better things can fall together.” – Marilyn Monroe. I believe in everything happens for a reason. Have you ever thought about everything that takes place might have a reason? Day by day you make mistakes; you say the wrong things;

Meanwhile‚ interest in the availability of transplantable organs has provided an incentive not to delay unnecessarily in determining that a person has died. Nowadays‚ we have technology that is so improved that we can bring dead people back to life. That there is no medicine for death – not true! In fact‚ there are drugs being developed‚

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
