Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

Reaction Turbine Nithin Mannil 08d01001 Aim 1. To investigate the Torque/Speed and Power/Speed characteristics of Single Stage Reaction Turbine. 2. To determine the Isentropic Efficiency of a Turbine. 3. To compare the characteristics of a reaction turbine at different values of inlet pressure. 4. To compare the maximum shaft power vs pressure and isentropic efficiency vs pressure. Theory Turbines are machines which develop torque and shaft power as a result of momentum changes in the

The 2008 World Economic Crisis: Global Shifts and Faultlines The last months of 2008 witnessed what is being called the worst financial crisis since the Great Depression of 1929-30. The first indications of a serious crisis appeared in January 2008. On 15 January‚ news of a sharp drop in the profits of the Citigroup banking led to a sharp fall on the New York Stock Exchange. On 21 January a spectacular fall in share prices occurred in all major world markets‚ followed by a series of collapses

Håvard Devold Oil and gas production handbook An introduction to oil and gas production ISBN 978-82-997886-1-8 PREFACE This handbook has been compiled for readers with an interest in the oil and gas production industry. It is an overview of the main processes and equipment. When we searched for a suitable introduction to be used for new engineers‚ I discovered that much of the equipment is described in standards‚ equipment manuals and project documentation. But little material was

Biology 104 Reaction Times Objectives: 1. Formulate and test hypotheses regarding reaction times. Introduction: Reaction time is a measure of how quickly an organism can respond to a particular stimulus. Reaction time has been widely studied‚ as its practical implications may be of great consequence‚ e.g. a slower than normal reaction time while driving can have grave results. Many factors have been shown to affect reaction times‚ including age‚ gender‚ physical fitness‚ fatigue‚ distraction

Reaction Time Reaserch Question: To design on investigation into stimuli ( sight/sound ) that may affect reaction time ( time taken for a response to occur in reaction to a stimulus.) Background information: Humans perceive their outside world through five senses: touch ‚sight‚ taste‚ smell and sound. The reason why we have the 5 major senses is to detect and discriminate among the signals that comes from our environment. These signals carry information necessary for us to support our vital

Coupled Reactions ABSTRACT A way to drive a non-spontaneous reaction forward is by coupling it with another reaction that is highly spontaneous‚ resulting to a spontaneous overall reaction. In this study‚ since the extraction of C(s) from CO2(s) is a non-spontaneous process‚ it was coupled with the oxide formation reaction of Mg‚ a reaction with high spontaneity‚ so that the process of the extraction of C(s) would proceed. The reactions and products which were a mix of black and white
