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

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

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

Daniel Thompson 10/31/14 NT1110 Unit 7 Assignment 1 Complementary Metal Oxide Semiconductor‚ or CMOS‚ is a widely used type of semiconductor. CMOS semiconductors use both NMOS(negative polarity) and PMOS(positive polarity) circuits. Since only one of the circuit types is on at any given time‚ CMOS chips require less power than chips using just one type of transistor. This feature makes them convenient for use in battery-powered devices such as laptops. Personal computers also contain a small amount

an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine. Usually iodine has a orange-yellow color‚ but iodine and starch react to produce a dark blueblack color‚ so iodine may be used as an indicator to show the rate at which starch is

Tori Suchy Physical Science Honors 1st block October 4‚ 2012 Balloon Powered Car Problem: In order to create a race car that can travel a minimum of eight meters powered by a nine inch balloon. We need incorporate Newton ’s Law of Motion including speed‚ velocity‚ and acceleration. Hypothesis: If a car were to be made out of homemade materials‚ then it would be possible for it to travel 8 meters powered by a nine inch balloon. Independent Variable: building the car from homemade materials

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
