Baker College Firefighters put their lives on a line every single day. They took an oath of taking a chance that might cut short their lives when they placed themselves in harm’s way in the public’s service. In figure 11.7 on page 451 in the Composition book shows firefighters in the World Trade Center Wreckage. Doing what they do make them a hero. They shows “courage, self-sacrifice, and also vulnerability of the human effort in the face of such colossal destruction” (Composition, 2012, p.451). On September 11, 2001 the horrific tragedy happened in the United States. 19 militants associated with Islamic extremist hijacked four airlines and carried out suicide attacks against targets in United States. Two planes were flown into the towers of the World Trade Center in New York City, the third plane hit the Pentagon just outside Washington, D.C., and the fourth plane crashed in a filed in Pennsylvania. The attackers were Islamic terrorist from Saudi Arabia and several other Arab nations. The horror in New York took a catastrophic turn for the worse when the south tower of the World Trade Center collapsed in a massive cloud of dust and smoke. Close to 3,000 people died in the World Trade Center, including a staggering 343 firefighters and paramedics, 23 New York City police officers and 37 Port Authority police officers who were struggling to complete an evacuation of the buildings and save the office workers that were trapped on

Identification of Unknown Solutions Laura Dolezalek Aurora Payne Submitted: 3/12/15 Abstract: This experiment was performed to strive to find the identity of certain solutions through chemical reactions, and the process of reasoning and putting puzzle pieces together. The experiment was performed, and data was collected. Certain clues were used to put names to unknown solutions. Introduction: During chemical changes, atoms rearrange, transforming the original substances into different substances…
ionic equation (redox equation) for this reaction. b) Which species is the oxidizing agent? 3) Give the oxidation number of S in the species FSO3- ? 4) Is this a redox reaction : 2HCl + Na2S -> 2NaCl + H2S ? 5) In a redox reaction, the increase in the oxidation number of one species is accompanied by the decrease in the oxidation number of another species. Explain. 6) Balance the half reaction : HNO3 -> NO2 in acid solution. 7) Balance the half reaction : NH3 -> N2O in basic solution. 8) The four…
Stage 2 Biology: Completion Practical Experiment: Enzyme rate of reaction Introduction: An enzyme is a natural catalyst which is made up of protein. Enzymes speed up chemical reactions without altering the products of the reaction and without being altered itself. Yeast contains the enzyme catalase. It is involved in the following equation which causes the breakdown of Hydrogen Peroxide into water and oxygen: Hydrogen Peroxide Water + Oxygen 2H2O2 H2O + O2 When we immerse small…
group of the sugar to produced a red-brown precipitate. Increasing levels of reducing sugar would be shown if the solution changed colors ranging from green, orange, red, or brown (Gurien, 2008). The biuret test for protein is used to detect the reaction of peptides and proteins. The reagent is made of sodium hydroxide and copper sulfate, which turns the solution violent in the presence of proteins (Garcia, 2002). The violet color is a positive test for the presence of protein, the more intense the…
