The temperature of the melt was raised to 185 °C and the melt was kept on stirring for 10 minutes. Subsequently, the alloy was cast into copper mold. To homogenize the alloys, the ingots were cold rolled to >90% reduction in thickness and re-melted at 180 °C for 10 minutes and cast into copper mold. Finally, the ingots were again cold rolled to >70% reduction in thickness and preserved for subsequent characterization and
Calcium is an element in the human body. It was discovered in 1808 by Humphry Davy. Humphry Davy was a chemist and an inventor. Calcium is a chemical on the Periodic Table with the symbol Ca and atomic number 20. Calcium is a soft gray alkaline earth metal, it is the fifth-most-abundant element by mass in the Earth 's crust.
Isoindoline is a heterocyclic organic compound with the molecular formula C₈H₉N and Phthalocyanine has a molecular formula of C32H18N8. Phthalocyanine is part of tetra-pyrollic family and it has nitrogen in all meso-positions. As mentioned before the compound has planar structure with an 18 π-electron system as predicted by Erich Hückel’s theory of aromaticity. The compound has four benzenes with 16 reactive sites because of this aromaticity and the covalent coordination of the central metal the compound is stable. So far, over 5000 of Phthalocyanine compounds have been prepared.
It has a melting point of 1585K (which is the same as 1312°C 2394°F), heat of fusion of 10,05 kJ/mol, and boiling point of 3546 K( 3273 °C, 5923 °F). Gadolinium has an electron configuration of [Xe]4f 75d16s2; and vapour pressure of7.39 Pa at temperatures of 2000 K.
Allow the wax in the cassette to solidify on the cold plate, and then place it in ice for 10 min until the wax is fully solidified. Note (you can store it in -4 OC until it processed) 4. Remove the cassette from the ice and separate the plastic cassette containing the wax and spheroids from the metal mold. 1.5 Section the Embedded Spheroid-Containing Plug and Create a Slide After the spheroid-containing plug has been embedded in paraffin, follow these

Verna Wang Hannah Palmer CHEM 101-069 Lab 11-19-16 Stoichiometry and Limiting Reagents Lab Report Purpose: We are using the reaction of sodium hydroxide and calcium chloride to illustrate stoichiometry by demonstrating proportions needed to cause a reaction to take place. Background: Just like a recipe would call for a specific amount of one ingredient to a specific amount of another, stoichiometry is the same exact method for calculating moles in a chemical reaction. Sometimes, we may not have enough of or too much of one ingredient , which would be defined as limiting and excess reagent, respectively. Ideally, every mole of each reagent would be used up, and theoretical yield, we are assuming that every last mole of the reactants would
The extraction of the crude product was conducted using sodium bicarbonate followed by distillation. The resulting product obtained was 4.491g of isopentyl Acetate, indicating a 70.02 percent yield. Based on the IR data, it was verified that the end products were as desired. The Isopentyl Acetate carbonyl bond
