Group No.: 3 Date Submitted: August 3 ‚ 2013 Experiment No. 4 : PAPER CHROMATOGRAPHY INTRODUCTION The objective of this experiment was to resolve a given sample into its components by paper chromatography‚ to evaluate the retention factor of each component in the sample and to compare the relative solubility of the various components of a mixture of colors in a given solvent. METHODOLOGY To prepare for the experiment‚ place solvent into a test tube‚ so that the level of solution

based on my research‚ wind energy is the result of the sun’s energy interacting with the earth’s surfaces. It is also an ideal renewable energy source that is infinitely sustainable; pollution free; doesn’t use fuel; and doesn’t produce greenhouse gases‚ toxic or radioactive waste. This type of energy is considered a green power technology because it has minor impacts on the environment. When using wind to generate electricity we use machines known as turbines and this turbines use blades that are

Introduction: The presence of greenhouse gases in the Earth’s atmosphere last year reached its highest levels since pre-industrial times‚ a report released by the United Nations World Meteorological Organization (WMO) warns recently. Even if we managed to halt our greenhouse gas emissions today‚ and this is far from the case‚ they would continue to linger in the atmosphere for decades to come and so continue to affect the delicate balance of our living planet and our climate. The latest

Experiment #4 (10/31/14) Lab Review Objective To introduce the basic molecules of life and to test for their presence in different substances. Introduction Macromolecules are in all forms of life. These organic compounds are carbohydrates‚ lipids‚ proteins‚ and nucleic acids. These are monomers and they link together into long chains that form polymers. Different reagents can be used to find the presence of these macromolecules. Proteins are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and sometimes

What are Greenhouse Gases? These are the gases that make up our atmosphere: Carbon Dioxide 89% Methane 7% Nitrous Oxide 3% Halocarbons 1% What is the Greenhouse Effect? The Greenhouse Effect is the way that gases in the atmosphere trap heat from the sun. They let heat in‚ but prevent most of it from escaping. It is essential for life because we need a certain amount of radiation to heat up our atmosphere. What human activities produce Greenhouse Gases? By burning fossil fuels such as coal‚ oil and

Poisonous gases changed the experiences of the people in the war for the worse. Breaking on impact‚ the canisters released yellowish green fumes that wafted slowly toward the French and African troops near the Belgian town of Ypres. As the fumes reached the Allied forces‚ soldiers realized the cloud was poisonous chlorine gas. Quoted in Dooly’s Great Weapons of World War I‚ one French doctor at Ypres expressed his horror: “I had the impression that was looking through green glasses. At the same time

Derricka Joe Period 5 1 Oct.‚ 2014 Lab Experiment One: Physical Properties Lab Analysis: For our first unknown‚ we observed the color and odor of the substance. The substance was a clumpy‚ white‚ crystal-like substance and it smells like new plastic. When we tested the solubility in water it resulted insoluble and in ethanol it resulted soluble. This substance could not be tested for electrical conductivity because the water was insoluble. We then tested for the PH value and it was neutral. The
