Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

1. OBJECTIVES (a) To determine the equivalent circuit parameters of a 3-phase squirrel-cage induction motor from laboratory test data. (b) To determine the performance characteristics of an induction motor under load conditions. (c) To control the no-load speed of an induction motor. 2. INTRODUCTION 2.1 Three-phase squirrel-cage induction motors An induction motor is a transformer with a rotating secondary winding. It has two essential components: an outer stationary stator and an

. Update Article NSAIDs and Kidney P Ejaz‚ K Bhojani‚ VR Joshi* Abstract NSAIDs are commonly used drugs. Even with the advent of selective COX-2 inhibitors‚ nephrotoxicity still remains a concern. The adverse effects of NSAIDs are mediated via inhibition of prostaglandin synthesis from arachidonic acid by non-specific blocking of the enzyme cyclooxygenase leading to vasoconstriction and reversible mild renal impairment in volume contracted states. When unopposed‚ this may lead to acute tubular

A. ENG237-02: Transients in RC and RL Circuits 0. Introduction The objective of this experiment is to study the DC transient behaviors of RC and RL circuits. This experiment has divided into 6 parts: 1. Charging curve from measured data ( R = 10M Ω and C = 4 mF ) 2. Draw the charging curve by the graphical method 3. Discharging curve from measured data ( R = 5M Ω and C = 4 mF ) 4. Draw the discharging curve by the graphical method 5. Display of the charging and discharging

OCS/WOCS Book Assignment - “Warrior Ethos/On Sheep‚ Wolves‚ and Sheepdogs” by Steven Pressfield/LTC (RET) Dave Grossman 1a. “The Warrior Ethos embodies certain virtues—courage‚ honor‚ loyalty‚ integrity‚ selflessness and others—that most warrior societies believe must be inculcated from birth” (Pressfield 3). 1b. “Their only response to the wolf‚ though‚ is denial‚ and all too often their response to the sheepdog is scorn and disdain” (Grossman 4). In these examples we look at the warrior in
