THE CONTACT PROCESS By: Kabeer Ali Teacher- Mrs. Sankar Class- Lower6 Science 2 INTRODUCTION The Contact Process is the name given for the manufacture of Sulphuric Acid (H2SO4(l)). There must also be specific conditions of temperature‚ pressure and catalyst for the reaction to occur effectively. I will also look at the effect of temperature‚ pressure and catalyst on the composition of the equilibrium mixture‚ with respect to Le Châtelier’s principle. THE PROCESS Firstly‚

Introduction: According to the oxford dictionary a “Contact sport” is a sport in which participants necessarily come into bodily contact with one another‚ this includes football‚ rugby‚ hockey and la cross. Children and parents must be warned of the mental‚ physical and social risk factors that are associated with contact sports before being able to participate in them‚ doing so will lead to less children taking unnecessary risk. One factor that parents should be aware of is the increased risk and

CONTACT PROCESS Sulfuric acid is one of the most important industrial chemicals Outline three uses of sulfuric acid in industry 1. The major use of sulfuric acid in Australia is in the manufacture of fertilizers such as ammonium sulfate and superphosphate. Superphosphate is produced by reacting sulfuric acid with rock phosphate. Ammonium sulfate is produced by neutralising ammonia with sulfuric acid. 2. Production of titanium (IV) oxide from titanium minerals eg ilmenite. Titanium is an important

The Canon Company was founded in 1933 with the sole intent of producing the world’s best 35mm camera. By the 1960s‚ the company began to explore the imaging technologies industry and started developing business machines such as printers and calculators. In 1967‚ the management slogan "cameras in the right hand‚ business machines in the left" was unveiled and in 1969 the company changed its name from Canon Camera Co.‚ Inc. to Canon Inc. (Canon Inc.‚ 2013) This was a turning point for Canon; it began

curious of their surroundings. Mary Louise Pratt describes this as creating a contact zone where parody‚ critique‚ and unseemly comparisons create social disruptions in which students are challenged. In her essay “Arts of the Contact Zone‚” she proposes that classrooms should take up this style of educating. What would a contact zone in a classroom perform like? Out of all the elements that are capable of creating a contact zone‚ parody is one of the more familiar choices that would behave well in

KEYPAD & SENSOR IN PIC MICROCONTROLLER. A 4X4 matrix keypad is useful for the function like a simple calculator or telephone. The 4X4 keypad has 16 keys which are arranged in push button switches in rows and columns. This keypad is followed by two other components‚ the 16-key encoder and the sensor pad. As you can see below is the diagram on a simple 4X4 matrix keypad. This requires users to key in numbers in decimals or hexadecimals depending on the encoder that is programmed to the 4X4

guiding principles? How did they come about? What are the antecedents that necessitated their emergence? What is (are) the importance of the history of these laws? These are some of the questions this work shall be addressing. Canon Law Defined Etymologically the word canon is derived from the Greek word “kavόνεҁ” meaning a stick or rod. It also means a standard measurement‚ the rule‚ norm‚ or yardstick.1 law on the other hand means a rule usually made by a government that is used to order the way

IEEE SENSORS JOURNAL‚ VOL. 6‚ NO. 3‚ JUNE 2006 631 Magnetic Sensors and Their Applications James Lenz and Alan S. Edelstein Abstract—Magnetic sensors can be classified according to whether they measure the total magnetic field or the vector components of the magnetic field. The techniques used to produce both types of magnetic sensors encompass many aspects of physics and electronics. Here‚ we describe and compare most of the common technologies used for magnetic field sensing. These include

Most of us would not readily think that eye contact had anything to do with language‚ or a person’s culture. While researching a topic for this paper I came across an article on cultural differences that contained a section about eye contact. I found it to be very telling‚ as to the reasons for either the lack of‚ or the reasons for eye contact. The article of reference is “Cultural Differences? Or‚ Are we really that different?” ( Gregorio Billikoph). This article discusses the differences in

common types of the metamorphic processes-contact(thermal)metamorphism‚ and regional(dynothermal) metamorphism occur within different sets of circumstances‚ as well as form different rocks as a result of each. The main difference between contact metamorphism and regional metamorphism is that in one case(contact metamorphism) the main factor and cause is temperature‚ whereas in regional‚ both temperature and pressure are involved. High temperatures during contact metamorphism occur at relatively shallow
