Privately Owned Critical Infrastructure

One privately owned infrastructure critical to the United States are chemical facilities. “The majority of Chemical Sector facilities are privately-owned: requiring DHS to work closely with the private sector and its industry associations to identify and prioritize assets, assess risk, develop and implement protective programs, and measure program effectiveness” (Department of Homeland Security, n/d, pg. ). Any attack or natural disaster at or around a chemical facility, such as a nuclear plant could be one of the most severe incidents…

Water Resources

1) Describe the path a molecule of water might follow through the hydrologic cycle from the ocean Evaporation takes place and the water molecule is taken high up in the atmosphere, where temperatures are very low. Continued accumulation of the molecules of water saturates the air and hence rain clouds are formed though condensation process. Precipitation in the form of rainfall, snow then occurs. Where precipitation occurs depends on whether or not the clouds were transported to land by advection…

Emergency Responses & Analysis of Chemical

Terrorism in the United States has emerged as a real threat because a lot can occur through the use of biological, chemical or nuclear weapons since each category has its own set of effects. Nuclear weapons can destroy lives almost instantly or their effects can be propagated into future generations. Biological terrorism is conducted by dispersing biological agents which cause dangerous diseases to the populace. Additionally, chemical terrorism occurs through the use of chemically derived weapons. (Bronstein & Currance, 2004)…

Hydrogen Peroxide and Iodine Ions

The reason for the blue-black complex is due to the formation of polyiodide chains during the reaction between starch and iodine. The amylose in starch forms helices with which the iodine molecules align, causing a transfer of charge. This charge transfer corresponds to the absorption spectrum, in which the blue-black colour is the complementary colour. The details of this reaction are not fully known yet. The strength and deepness of the colour is dependent on the amount of amylose present….

´╗┐determining the Stoichiometry

1.) On graph paper, plot the milliliters of reactant #1 versus volume of precipitate for each reaction. For the copper chloride graph, draw the two best-fit straight lines through the data points and determine their point of intersection. Cu:PO4 stoichiometric ratio = 3:2 Balanced Equation = 3CuCl2 + 2Na3PO4 Cu3(PO4)2 + 6NaCl 2.) For the iron nitrate graph, draw the best-fit line through the ascending data, and a smooth curve through the descending data. Determine their intersection point. From the…

đÁhe Chemical Weapons

Regarding the issue, the article that supports the chemical weapons presented that (1) some countries particularly US developed a program that aims for uncomplicated and more accessible ways to identify biological agents, and (2) chemical weapons can be used by nations in preparation for their defense against terrorism. On the other hand, chemical weapons are opposed by the antagonist by citing that: (1) chemical weapons create destructions on civilians like what happened on the Moscow Hostage Rescue, and (2) Chemical…

Computerized Data Acquisition of a Second Order Reaction

The rates at which reactions occur depend on the composition and the temperature of the reaction mixture. Usually the rate of reaction is found to be proportional to the concentrations of the reactants raised to a power.1 There are many reactions that have a rate law in the form of: (1) v = k[A]a[B]b According to reference1 the power to which the concentration of a species (product or reactant) is raised in a rate law of this nature is the…
