Paragraph 1 Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β- FePO4. Crystal structure is defined as the orderly arrangement of atoms, ions or molecules in both liquid and solid states. Quartz has a trigonal crystal system and a six-sided prism with six-sided pyramids at each end. Quartz possesses a macromolecular structure and does not contain isolated ions. The crystal structure of quartz consists of the SiO4 silicon oxygen tetrahedra, where each oxygen

Indiana Jones and the Kingdom of the Crystal Skull is about a man who happens to be an agent that travels the world on missions. On this mission he is traveling to Peru to find the missing crystal skull and put it back where it belongs. Not only is he looking for the skull, he is helping Mutt find his mom, who was kidnapped, and Ox. Jones and Mutt finds a coded map in Ox’s prison cell where he was trying to figure out how to find the crystal skull or how to put it back. This journey will lead to

and important. Although the use of sugar will not be the same for every solution, this would just be something for other tests to be based off of. Another importance of this experiment is to show the effects and properties of supersaturation using crystal growth. Background: To be soluble it means an object or substance can be dissolved, this is especially true of sugar when making rock candy. A solution is a liquid mixture comprised of a solute and a solvent. In this case the sugar is the solute

Snowflakes are small and their structure is simple at very low temperatures. At higher temperatures the distinct flakes may be formed from a very large amount of ice crystals - creating a complex star shape and can have a diameter of several inches. (Met Office, 2014) Snowflakes are accretions of several snow crystals. Most snowflakes are less than 1.3 centimetres (0.5 inches) through. Under some conditions, usually needing near-freezing temperatures unstable atmospheric conditions, and light winds

they made of? How did they get here? All of them had researched the structure of the crystals and had developed their own theories. Carbon-based, like many crystalline compounds, and similar in hardness to the diamond. It can be cut evenly to fit pendants and sequins. But the discovery that baffled scientists was that the structure of molecules was attracted to each other so well that when a chipped piece of crystal was reintroduced to the rest of the structure, the piece fused itself back to the main

of the environment affect the growth of crystals in fudge? Hypothesis: If crystallized fudge is cooled under two different temperatures, then the lower temperature will grow bigger crystals than the high temperature, because solubility in cold temperatures is lower. Why fudge was chosen: Crystals form in igneous rocks, and this experiment was chosen to explore the sizes of crystals formed under different conditions. The topic was decided upon because crystals are formed under extreme conditions, and

have mixed together. We then weighed this liquid which will help us determine the percentage yield. We then filtered the liquid off which gave us the amount we obtained. We then left the liquid for a week so that the liquid had time to turn into crystals,

where he was good at his job and could make his father happy, but instead he persevered in order to do what he set out to do; see other parts of the world. Towards the middle of Santiago’s journey towards his personal legend, he stumbles upon a crystal shop. He suggests to the owner that there

Introduction: Benzopinacol can be prepared from benzophenone in presence of sun light (photochemically) using isopropanol as the reducing agent in presence of acetic acid. Acetic acid is added to prevent the cleavage of benzopinacol to benzophenone and benzhydrol by the alkali derived from the glass container used for the reaction. Benzopinacol obtained in the first experiment is converted to benzopinacolone by heating under reflux (5 minutes) with glacial acetic acid containing trace amount of iodine

Selecting the item he needed, Sylvester placed them on the counter in the order of their use. Knowing that he would need some hot water, he hung the largest pot he had in the fireplace. After filling the pot with water, he then added some wood to the fire before returning to the table. After mixing the special red dye in a medium glass container, he set it on the table. It is now time to combine the magical ingredients in a beaker. Combining the ingredients they are to be gently shaken not sutured

The strategy recommended would match both external and internal fit that help Ice-Fili to increase its current market share (5%), maximise its long term profits and to achieve a sustainable competitive advantage. To dominate the Russian ice cream market and maintain its market leader position, it has to brand itself as the top historical Russian ice cream producer and strengthen its core product in the impulse segment. Due to little product differentiation, there is low brand loyalty for consumers

Everything in the world is made of tiny particles that have different amounts of stickiness, are differently sized and spaced, and have different speeds of motion. Particles are sticky, but have different amounts of stickiness. In the lab, Swab the Deck, I saw the alcohol slowly disappear, because the alcohol particles were sticky to the air particles. In the lab, Drops on a Candle, I watched the oil spread out and leave residue while the water stayed in a dome and left no residue, because oil is

This was determined by comparing the melting points of the purified unknown crystals to the crude unknown. The known melting point range for acetyl salicylic acid is 135°C -136°C. The Unknown’s melting point was slightly off at 128.6°C - 132°C. This can be due to impurities of the crystals during the purification process. There were a few steps in the experiment that may have contributed to impurities in the unknown crystals. In the beginning of the experiment, the column with alumina was used to filter

carrier continues to gestate a fetus or not in cases where the fetus has a severe, life-threatening physical or mental deficit (Cohen 2013). The gestational carrier, such as Crystal Kelley, gestates a fetus for a couple or potential parent and has no genetic tie to the child, unlike a surrogate (Byrn and Snyder 2005). In Crystal Kelley’s case, the intended couple wanted to abort the fetus because it had severe health defects such as holoprosencephaly and heterotaxy, in which the brain is not divided

CRYSTAL METH In today’s society, a lot of young adults struggle with drug usage. These young adults need to know the dangerous effects and prevention of drugs like crystal meth. Crystal meth is a pure form of methamphetamine. It is called “crystal” meth because of its clear, crystal-like appearance. Unlike most other drugs, users report that they became addicted after trying crystal meth just once. Crystal meth initially causes feeling of intense pleasure, but continued abuse destroys the brain’s

Crystal City Alien Enemy Detention Facility in World War II—Crystal City, Texas The shock generated by the unprovoked attack by the Japanese on Pearl Harbor on December 7, 1941 resulted in many decisions by American government officials that would have enduring consequences. That act was, of course, the catalyst that forced the United States to enter World War II. However, another decision made shortly following that attack resulted in the internment of thousands of Japanese Americans in Hawaii

Introduction: A crystal is a solid whose atoms are arranged in a specific repeating pattern. Real crystals undergo years to grow, but today's scientists have obtained a way to grow crystals right in the lab. They have also been effective in finding a way for people who aren’t scientists to grow crystals in the comfort of our own home. Although they may not be the same crystals we wear as jewelry, they give us a basic idea of the unique types of crystals that are made, formed and grown all over the

“The Alchemist” by Paulo Coelho through a character known as the Crystal Merchant. The author adds this character to the main character (Santiago) story not only to give a new lesson down the road to Santiago but to the readers as well. The novel reveals that Coelho emphasizes the significance of the outcome of one giving up their dreams due to fear of failure through the crystal merchant, a character who has done just that. The crystal merchant represents the fear of change and the comfort of routine

Child in the Crystal "SHEN TANFENG!!!.......". In a cave there was a hundred men dressed in purple robes with an insignia of black flame on there backs.For some reason the black flame insignia was easily disernible from the black robes ,this is because it was created using mana . These men were all members of the Shen clan, at this moment they were surronding a old man and a young girl. The old man had white hairand was medium built. His face was full of wrincles and liver spots he was

In the book The Crystal Cave by Mary Stewart, the protagonist Merlin is deemed a “bastard” child because his mother never reveals his father’s identity. Therefore, Merlin grows up fatherless, but does this hinder Merlin, or is this an advantage? During the time period which this book takes place, a person’s parentage determines every aspect of their life. It determines the child’s title (last name), lineage, and inheritance. If their father is a noble or a king, then, that child will have a high
