Determination of Trace Amount of Copper and Zinc in an Aqueous Solution by Atomic Absorbance Spectroscopy Abstract: The purpose of this experiment is to analyze a sample containing copper and zinc in trace amounts‚ where standard addition method was used and the instrument used is the atomic absorbance spectroscopy. The amount of copper obtained was 0.569 ppm ± 0.015 and for zinc we obtained 0.42 ppm ± 0.0027. Introduction: This method implies the excitation of particles in the solution sample

DATA REPRESENTATION CPU uses electronic elements such as switches‚ which are represented in two states i.e.‚ on/off state (high/low state). These two states are indicated as 1 and 0. In other words‚ computer operates only in two digits 1 and 0. Hence‚ our ordinary decimal number system consisting ten digits (0-9) do not suits the data representation of CPU. It works with simple binary system. BINARY NUMBER SYSTEM It uses two symbols or digits i.e. 0 and 1. And all the symbol‚ Arithmetic

ENERGY CRISIS AND NUCLEAR ENERGY REQUIREMENT IN INDIA 1. The year 2005-06 is marked in the history of India – US relations as an important milestone in the mutual rediscovery of each other. It marks one of the most significant departure from long held relations. It is the biggest foreign policy challenge facing India after a gap of more than 30 years India and US agreed to resume cooperation in the field of nuclear energy. Until now ‚ US viewed India as a nuclear weapon capable state

think about how this war really ended? It obviously had to have taken a very powerful army or leader‚ but that wasn’t the case. What really caused this national turmoil to come to an end was the dropping of the most deadly weapon known to mankind: the atomic bomb. The year is 1939‚ and a world war is on the rise. America really wanted to create a weapon that they could use if worse comes to worse. Albert EInstein had written

Alternative Energy Alternative Energy whether used for transportation or utilities such as generating electricity for home or business is a very significant subject going on right now because of the benefits it would provide for us‚ such as environmental‚ economic‚ job security and energy security. I believe alternative energy would be beneficial to our society‚ especially if it is used in transport; there is many other better‚ leaner and reusable energy sources out there‚ for example fuel for

The Atomic Bomb The atomic bomb is a powerful‚ explosive nuclear weapon. It is fueled by the fission of the nuclei of specific amounts of plutonium or uranium‚ in a chain reaction. The strength of the explosion created by one of these bombs is equal to the strength of an explosion created by thousands of tons of TNT. The atomic bomb was first created in the early twentieth century. Physicists in the United States and Europe had discovered that the fission of uranium could be used to create
