The Geritol Solution What is the basis for Martin’s premise that seeding the ocean with iron would help combat global warming? The idea of stimulating plankton growth with iron grew out of the fertile mind of the late John H. Martin‚ an oceanographer at Moss Landing. Martin sought originally to explain a long-standing mystery concerning barren waters in the Antarctic‚ subarctic‚ and equatorial Pacific Oceans. With the abundant concentrations of nutritious nitrate and phosphorus in

Chemistry 112: Anion Analysis Page 7 ANION ANALYSIS M uch of the work you will be doing in the Chemistry 112 laboratory will be concerned with identifying positive and negative ions‚ that is‚ cations and anions‚ in solutions whose composition is unknown. This procedure is called QUALITATIVE ANALYSIS. The modern chemist frequently wishes to identify the constituents in a very small amount of substance‚ and so he depends heavily on instrumental methods of analysis. While the procedures

Conductivity of Ionic and Molecular Aqueous Solutions Abstract Aqueous solutions that have free ions have higher conductivity values than solutions with most molecules. The purpose of the experiment was to see if ionic strength of an aqueous solution determines its conductivity. We tested each compound by putting the conductivity probe into its aqueous solution. Then the computer would analyze the data and give us a conductivity value. After each solution was tested‚ we used deionized water to

In fact‚ relapse to drug abuse occurs at rates similar to those for other well-characterized‚ chronic medical illnesses such as diabetes‚ hypertension‚ and asthma. As a chronic‚ recurring

A buffer solution can maintains a narrow range of pH even when strong acid are added. In our experiment‚ we can see water is not a buffer‚ water can undergo very big changes when small amounts of strong acid or strong bases are added. When the strong acid‚ 100µl HCl was added into the dd water‚ the pH value changed from 7.38 to 5.83 which mean the dd water has turn into acid. The same phenomenon occurs while strong base‚ 100µl NaOH was added into the dd water. The pH value changed from 7.07 to 9

of Youth Sports American culture encourages participation in both the team and individual sports‚ in favor of the physical‚ mental‚ and social benefits they provide the contestants. Sports today constitute a major portion of a child’s development. Participants enjoy physical‚ mental‚ and social benefits‚ yet youth sports continue to endure plenty of criticism. Skeptics allege competition causes damage to the self-images of countless children who lose a match‚ miss a basket‚ or strike out. Still
