Formal paper number 1 Professor Tolentino Maria Oyervide EXPERIMENT #4 IONIC AND COVALENT COMPOUNDS Abstract: This experiment was divided in four steps to find the electrical conductivity of covalent and ionic solutions. There were four unknown solutes A‚ B and C. Each had a specific weight and was dissolved in a certain amount of solute to form either the covalent or ionic solution. Covalent compounds are made up of molecules which are electrically neutral. Ionic compounds are composed

The fusion of Eros and Thanatos in A Streetcar Named Desire Death and desire have been linked closely together ever since Freud identified Eros (the instinct of life‚ love and sexuality) and Thanatos (the instinct of death and destruction) as two coinciding and conflicting drives within human being (Cranwell). In Tennesse Williams’ play A Streetcar Named Desire (1947) these fundamental drives of Eros and Thanatos dominate the story from the beginning to the end. This becomes particularly clear through

CORONA PHENOMENON AND LOSS As the voltage on a line conductor system is raised beyond a certain limit‚ a point is reached when a pale violet glow appears on the conductor surface‚ together with a slight hissing noise and a smell of ozone. This phenomenon is known as corona. For an overhead transmission system the atmospheric air‚ which is the dielectric medium‚ behaves practically like a perfect insulator when the potential difference between the conductors is small. As long as the air is

How can one balloon reach across space and pull a second balloon towards it or push it away? The best explanation to this question involves the introduction of the concept of electric field. Action-at-a-distance forces are sometimes referred to as field forces. The concept of a field force is utilized by scientists to explain this rather unusual force phenomenon that occurs in the absence of physical contact. While all masses attract when held some distance apart‚ charges can either repel or attract

Deflection of an Electron Beam by an Electric Field Nicole N Lab Problem 1.4 – February 3‚ 2011 Problem Statement: We were asked to test the design of an electron microscope to determine how a change in the electric field affects the position of the beam spot. The goal is to find out how different variables‚ such as charge of the deflection plates providing a vertical electric field and initial velocity of the electron beam will affect the amount of deflection the electron beam experiences

Electricity and Magnetism Electricity Circuit symbols Potential difference The energy which is delivered to an electric circuit comes from the supply. The greater the potential difference of the power supply the more energy is delivered. Potential difference is measured in volts‚ which has the unit symbol V. Cells in series The more chemical cells that are connected in series the greater the potential difference that they supply. The potential difference of a number of cells connected
