best way to go. For the past few years there has been an ongoing debate about oil drilling in Alaska. Alaska is often referred to as America’s last frontier. It is wild and natural and it has undisturbed resources that are currently being looked at for the future. Drilling for oil in Alaska has become a controversial issue for several reasons. Environmentalists and scientists remain at odds over the affect the drilling will have on the future of the area. Some of the concerns involve the Eskimos

Robert Frost’s "Two Tramps In Mud Time" On the surface‚ "Two Tramps in Mud Time" seems to display Robert Frost’s narrow individualism. The poem‚ upon first reading it‚ seems incongruent‚ with some of the stanzas having no apparent connection to the whole poem. The poem as a whole also does not appear to have a single definable theme. At one point‚ the narrator seems wholly narcissistic‚ and then turns to the power and beauty of nature. It is‚ however‚ in the final third of the poem where the

Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants

Title Name Subject Date Pros and Cons of Natural Gas Drilling Fossil fuel has a high demand in any country. In this century‚ the innovations in the 21st century enable the country to do exploration and invent other drilling technologies. The drilling technologies make it possible for easy accessibility of the reserves that were previously inaccessible. The Marcellus Shale has a lot of natural gas and this has brought development to the developments in the three states. The developments include

Procedure: Melting point of RCO2H Before observing the melting point of the unknown sample‚ the melting apparatus had to be standardized with a standard substance having the melting point of 151°C-153°C. After placing a small sample of the standard in a capillary tube and inserting the tube into the sample tube holder‚ the plateau on the device was set to 15°C below the expected melting point. After its temperature reached the plateau‚ the temperature increment was set at 1°C per minute‚ and the

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚
