The Works Bomb One of the coolest things about chemistry has to be blowing things up. It gives you the satisfaction of knowing your experiment worked (or sometimes failed)‚ plus it’s just a lot of fun to watch something blow up. One of the most popular experiments seems to be the Works bomb. It’s not a “bomb” in the sense that it explodes into flames and leaves a big hole in the ground‚ but it makes an extremely loud bang and steams a little bit. It’s a pressure bomb. The gas created from

BROOKLYN BLOOMS SEED BOMB WORKSHOP What: Seedbombs‚ or seedballs are a mixture of clay‚ compost and seeds that are designed to improve ecology in blighted often hard to reach areas. The components are simply mixed together into balls that can easily be dropped or thrown in an appropriate place. How: The clay prevents the compost and seeds from being washed away in rain and keeps them damp. The seeds will sprout plants that need the compost for nutrients required for successful early growth

University of Nebraska at Omaha Bomb Calorimetry Physical Chemistry 3354 Enthalpy of Combustion: 1‚2-diphenylethane January 6‚ 2014 Author: Jon D. Paul Signature Professor: Dr. Edmund Tisko Date Abstract Experimentation involving constant volume calorimetry produces the heat of reaction for many substances. When choosing adiabatic conditions we are allowed to focus on the reaction system while neglecting everything else. The reactions that are studied should proceed relatively

The dropping of the atomic bombs on Hiroshima and Nagasaki remains among the most controversial events in modern history. Historians have actively debated whether the bombings were necessary. What effect they had on bringing the war in the Pacific to an end and what other options were available to the United States. As American policymakers struggled with how to use a powerful new technology and what the long-term impact of atomic weaponry might be‚ not just on the Japanese but on domestic politics

Bomb Shelter You own a bomb shelter. It can hold all of your loved ones‚ and has room for five other individuals. Using the list below‚ select five individuals to take with you into the bomb shelter if a nuclear war is imminent. 1. Space Engineer- has worked with NASA and is valued for knowledge in all aspects of nuclear physics‚ chemistry‚ genetics and biochemistry. 2. Police office- has worked in inner city environments. Is strong‚ honest‚ and able to deal with authority. 3. Social

heat of combustion for naphthalene. This is the some basic bomb procedures. In this experiment‚ we us naphthalene as a fuel in bomb calorimeter which naphthalene powder is turned to pellet using pellet press. The fuel is burnt at constant volume condition in a high pressure container (the bomb). The whole bomb‚ pressurized with excess of oxygen. The mass of iron wire‚ ma =0.02g. The mass of naphthalene pellet with iron wire‚ mb =0.38g. The bomb is submerged in 850g of water and the initial temperature

suggestions come to mind‚ raging from the invention of the iPhone to the Civil War. I believe that the most important event was the dropping of the bombs on Hiroshima and Nagasaki. The dropping of the bombs saved over a million American lives‚ introduced America as a world power‚ and‚ if not most importantly‚ was the first steps into the Cold War. If the bombs had not been dropped‚ many American lives would have been lost‚ and the war could have dragged on for many more years. If “Operation Downfall”

Jennifer DaRosa Honors Chemistry Period 1 Group 8 Mrs. Chan Topic: Chemical Explosions Due Date: 9/30/16 For this experiment‚ a few scientists are researching the changes in gas pressure and launch velocity needed to send a film canister across the room using the ignition of ethanol. The independent variable would be the different types of flammable sprays. The dependent variable would be how far the explosions are sent across the room. The constant would be way the device is built for every
