News Broadcast- News Reporter: Sorry for the interruption. We have breaking news pertaining to the Cold War. The Soviets have developed an Atomic Bomb. Now the Soviets being our enemies could drop the bomb at any time. So you viewers out there need to be prepared. We are now going to show you three scenarios in how to protect yourself against an Atomic Bombing. Scenario 1 (screens shift from News broadcast to Person cooking in kitchen) Raianne voice over: Scenario 1. You’re preparing

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

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

Determination of the Enthalpy for Decomposition of Hydrogen Peroxide Objective: To construct a coffee cup calorimeter‚ measure its calorimeter constant‚ and determine the enthalpy of decomposition and formation of hydrogen peroxide. Background: This experiment is a classic thermodynamics lab. In it‚ we attempt to measure the enthalpy (H) of a chemical reaction. The main obstacle is that this is a quantity that cannot be measured directly. It instead is observed as heat from one substance is transferred

theory doesn’t apply (A) H (B) He+ (C) Li2+ (D) Na+ Solution: Bohr theory is not applicable to multi electron species ∴ (D) Problem: If the radius of 2nd Bohr orbit of hydrogen atom is r2. The radius of third Bohr orbit will be (A) 4/9r2 (B) 4r2 (C) 9/4r2 (D) 9r2 Solution: r = n2h2/ 4π2mZe2 ∴ r2/r3 = 22/32 ∴ r3 = 9/4r2 ∴ (C) Problem: Number

Atomic War or Peace? Was the dropping of the atomic bomb on Japan justified? Many people believe that it was very justified‚ but was it? Some reasons could have been the attack on Pearl Harbor‚ the destruction of Japans power to make war‚ also what seemed to the only answer to end war. “I wouldn’t hesitate if I had the choice. I’d wipe ‘em out. You’re gonna kill millions of innocent people‚ but at the same time we’ve never fought a war anywhere in the world where they haven’t fought and killed

Atomic Structure & Electricity 1. Draw an atom with an atomic number of 12. Label the protons‚ neutrons‚ and electrons. Use the periodic table to identify which atom you have drawn. 2. How many valence electrons are present in this atom? 2 3. Would this atom prefer to gain or lose electrons? Why? Lose‚ because the octet rule dictates that if there is less than 4 valance electrons‚ they would prefer to leave the atom. 4. Describe the differences between conductors‚ semiconductors

all having their own drawbacks. But‚ the one that will be focused upon in this analysis is hydrogen as a source of fuel‚ and the technology leading the way to making it a reality. This technology would affect everyone in one way or another if correctly used. So we must ask if this technology is beneficial to us‚ how it might hurt us‚ and whether it is worth pursuing from an ethical stance. Background: Hydrogen has already been under the micro scope for many years as an alternative fuel source to us

The Great Invention Of The Atomic Bomb Darion Mealing English 12 Mr. Owens Block 4 02/06/14 If you were asked what the greatest invention to help or impact mankind‚ what would you say? Most people would begin to talk about automobile‚ engines‚ and other machinery. Weapons are also a major reason we are what we are today. A special weapon stands out as the big advantage of why we won the battles in World War II‚ It’s called the Atomic Bomb. It is a great invention

The invention of the atomic bomb certainly brought extreme fear into Canadians’ lives after revealing its astonishing power through the massive destructions done at Hiroshima and Nagasaki. Although most people did not speak of this fear but it can be clearly seen throughout the cold war when the arms race between the two super powers at the time‚ the United States and the Soviet Union‚ split the world into two halves. On one side‚ there was the communist countries allied with the Soviet Union‚ and
