pure forms of sulfanilamide and fluorene. After the filtration step in the first experiment, the pure sulfanilamide appeared to be a mix of small, white and yellowish crystals, resembling a powder. However, sulfanilamide should have crystallized into large needles, which indicated that either there was too little solvent or the crystals formed too quickly. As shown on Data Table 1, the percent yield was 69%, therefore implying that the crystallization of sulfanilamide experiment was not completely successful

the students of Eastdale High School, Crystal used to be a nobody. That is until she met Geena. For better or worse, Geena was a stepping stone for Crystal to evolve her way into a popular lifestyle. Crystal was making an obvious transformation, however, the transformation went against her true self: “Geena taught me how to dance and how to steal. Geena also told me I’d have to do her homework sometimes so whe wouldn’t get put on academic probation. Old Crystal would have had something to say about

Calcium- Phosphate Ceramics (CPC) Calcium phosphate ceramics are a type of ceramics with varying calcium-to-phosphate ratio, the important properties of calcium phosphate biomaterials are their bioresorption and bioactivity. The most widely used calcium phosphate based bioceramics are hydroxyapatite (HAP) and β-tricalcium phosphate (β-TCP). Synthetic Hydroxyapatite (HA) is a calcium phosphate whose stoichiometric formula corresponds to Ca10(PO4)6(OH)2 with calcium-to-phosphate ratio is 1.67, it

only one that crystalized. The other sugars did not crystalize or stick to the stick but did form a top crystalize coating on top of the glass cup. III. Crystallization is the formation of sugar crystals in a sugar syrup. Crystallization is the natural or artificial process of formation of solid crystals from a homogenous (“the same

Experiment 2 Date: 24 January 2006 Title : Crystallization of a Crude Sample Objective : Preparation of pure diphenyl via crystallization of crude diphenyl dissolved in ethanol. Structural Formula of Organic Substances Involved : Diphenyl Ethanol Apparatus : Round-bottom flask (100 mL), measuring cylinder (50 mL), conical flask (50 mL), filter flask, beaker (100 mL), stemless glass funnel, Hirsch funnel, capillary tube, long glass tube, watch glass, glass vial, water condenser

Effect of processing technique and core thickness on fracture resistance of Lithium disilicate copings having two different thicknesses Keywords: IPS e.max;Press; CAD / CAM; core thickness; fracture strength. Introduction High-strength All ceramic restorations, with different composition, structure, and processing methods, have been introduced as an alternative to metal ceramic restorations in many applications (1). Due to their translucency and strength, IPS e.max ceramics

all are used in a crystal form. Certain types of alum are used in baking, medicine, or pickling. The alum created in this lab became a crystal in an octahedral form. The purpose of this lab was to create alum crystals from aluminum foil and various solutions. Aluminum is a common metal and by adding an aqueous solution to small pieces of aluminum, a crystal structure can be formed. Aluminum is being reduced in the reaction contributing to the formation of the octahedral alum crystal. Hydrogen was being

Please refer to the above diagram for reference. The hydrogen bond between the hydroxyl group 031-H58 and the ketone oxygen O25 is the only significant hydrogen bond in the crystal structure. There is also a very weak intermolecular hydrogen bond between C25-H50 and F7 which has been attributed to the packing of the Paliperidone crystal. Another weak intramolecular hydrogen bond C30-H57 and O25 has been attributed to the conformation of the molecule. Paliperdone is not a tightly packed molecule and only

Crystals are all beautiful creations! When an individual thinks of crystals, they typically think of the type that are found and kept as valuables but that’s not all that crystals can be, they can also be edible. For example, Rock Candy is a type of crystal that is edible. These types of crystals are sugar crystals. Now, the real question is, is it possible to make sugar crystals from the comfort of your own home? In order to make sugar crystals you will need the following supplies; 1 cup of water

Diamonds are the ultimate gemstone, with few weaknesses and numerous strengths. Diamonds are known for being the hardest substance on earth, but few know diamond is four times harder than the next hardest natural mineral. One of the diamonds only flaws are its cleavage. A skilled diamond jeweler can prevent a diamond from being split by positioning it to be struck at the perfect placement. Diamonds have a wide color range, high refraction, low reactivity to chemicals, and extreme hardness and durability
