Shawn Girouard 2/5/15 Chapter 1 Dessler HW 1. Determine the latitude and longitude of the White House‚ the Kremlin‚ the Pyramids of Giza‚ and the point on the opposite side of the Earth to where you were born. Use an online tool (e.g.‚ Google Earth) or an atlas (which you can find in any library). White House: 38.8977° N‚ 77.0366° W Kremlin: 55.7517° N‚ 37.6178° E Pyramids of Giza: 29.9792° N‚ 31.1344° E Opposite of where I was born: 36.385913° S‚ 59.677734° E 2. a) Convert the following temperatures

GROUP B MODEL ANSWER Howard et al.‚ Temperature-induced structural changes in CaCl2‚ CaBr2 and CrCl2: A synchrotron X-ray powder diffraction Phys. Rev. B 72‚ 214114 (2005). DO NOT PLAGIARISE THIS MODEL ANSWER Paragraph 1 The polymorphs involved are the halides in tetragonal rutile (TiO2) structure and the halides in so-called calcium chloride structure. As the name implies‚ the unit cell of halides in tetragonal rutile structure is tetragonal‚ with the lattice parameters a=b≠c and α=β=γ=90o

DETERMINATION OF BOILING POINTS Introduction: The boiling point of a compound is the temperature at which it changes from a liquid to a gas. This is a physical property often used to identify substances or to check the purity of the compound. It is difficult‚ though‚ to find a boiling point. Usually‚ chemists can only obtain a boiling range of a 2 - 3oC accuracy. This is usually sufficient for most uses of the boiling point. Purpose: The purpose of this experiment is to determine the boiling points

Unit 6 Problem Set 1: Applying Thermal Expansion Learning Objectives and Outcomes Calculate the thermal expansions of solids and liquids. Assignment Requirements Complete the following problem. Show all of you work. The formula for the linear expansion of a solid is given by: An iron rod (α = 11.8 x 10-6 C-1) has a length of 1000 meters (or 1 km) at 0 degrees Celsius. If the rod must expand 10 cm to bridge a gap‚ to what temperature must the rod be heated? Increase in L = a*(T-To)L

Biodegradable Styrofoam Made from Milk and Clay Objectives - The researchers will intend to develop the Styrofoam-plastic out of mostly milk proteins and clay. The material is lightweight‚ sturdy and largely biodegradable. The researchers will make sure that the end result doesn’t smell like spoiled milk. - Casein—milk proteins—is already used in making paper coatings and has an excellent barrier properties. But it has its limited mechanical strength and is water resistant. To make it more resilient

Conclusion My hypothesis was if the temperature increases the Vitamin C content will decrease. The results indicate that my hypothesis was wrong; temperature does not affect the content of Vitamin C left in the orange juice. Future Considerations If I were to conduct this project again I would measure the temperature more accurately‚ conduct more trials‚ keep the juice at a high temperatures for a longer time and use another juice with a lot of Vitamin C content. The purpose of this experiment
