very fierce group of people. As a result of that they invaded Britain while the Romans were still in control. But just like other people some Anglo-Saxons came to Britain to fight‚ while others came peacefully‚ to find land to farm. They loved tales about brave warriors and their adventures. A favorite story told was Beowulf‚ a heroic prince‚ kills the fierce man-eating monster Grendel‚ and Grendel’s an equally horrid mother. “The Steel-edged blade lay where he’d dropped it. If weapons were useless

Chebyshev’s Theorem and The Empirical Rule Suppose we ask 1000 people what their age is. If this is a representative sample then there will be very few people of 1-2 years old just as there will not be many 95 year olds. Most will have an age somewhere in their 30’s or 40’s. A list of the number of people of a certain age may look like this: |Age |Number of people | |0 |1 | |1 |2 | |2 |3

In conclusion to the distillation lab‚ I think our data shows that our experiment went well. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains. The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned off. To view the apparatuses used in the experiment look at the attached pictures. To

Barry Allahyar Dr. Dodd CHEM 2122 2010-09-16 Experiment 19: Fischer Esterification‚ Conclusion The objective in this experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism

Introduction: Copper has played a vital role in past civilizations and continues to do so today due to its many properties as a metal. Although advantageous in today’s economy and also in human bodies‚ high concentrations of copper can prove toxic to our health and even pollutant to the environment. By altering the element through a number of chemical reactions including redox‚ metathesis‚ decomposition‚ and single replacement reactions‚ the cycle will be complete once solid copper is recovered.

The statement above demonstrates evidence of why the 14th amendment was added to the Constitution. In conclusion‚ the major principles in democracy consist of different variable including having individual right that are specified by amendments. Among these rights are freedoms such as freedom of speech‚ right to vote‚ right to due process of the law all rights

In order to find the formula of the copper chloride hydrate‚ we had to separate the compound to find the mass of water and copper. To begin this process‚ we evaporated the water and created an anhydrous compound‚ meaning we were left with only CuxCly. By calculating the weight of both the anhydrous and the hydrated compounds‚ we could conclude that the difference in the weights was the weight of the H2O. From this we were able to calculate the percent composition of CuxCly and H2O (see Calculations:

Alum Lab Conclusion The purpose of this laboratory was to use two different techniques to attempt to identify the melting point and the mole ratio of hydrated water to anhydrous aluminum‚ potassium‚ and sulfate of AlKSO4. The hypotheses were: if the alum was put in a capillary tube the melting point of alum will be able to be determined; and the water of hydration in alum crystals will be possible to determine if the alum is heated with a Bunsen burner.
