Idenitfication of Substances by Physcial Properties
Chemistry
Melting Point
Water
Report- Identification of Substances by Physical Properties The purpose of this lab was to see how certain substances; Naphthalene, Toulene, and and 2 unknowns (one liquid, one solid) react with 3 different solvents. To identify the two unknowns, testing needs to be done to find the density of both the liquid and the solid, determine…
Structural Methods in Inorganic Chemistry Sample
Chemistry
In order to synthesise our metal composites. we were able to do both Copper and Ruthenium metals. From this. we combined each metal composite with DMSO by refluxing the compound. The metal composites were analyzed through their thaw point and IR spectrometry to find whether the metal bonded to a Sulfur atom or an Oxygen…

Experiment: the Effect of Salt on the Growth of Grass
Chemistry
Nature
Water
During the winter months, salt is regularly applied to the driveway to dissolve snow. However, in the spring, it becomes evident that grass does not grow within a three-inch radius from the driveway and appears to grow at a slower rate up to one foot away. This raises the question of whether salt hinders grass…

Chemistry
Melting Point
Nature
Abstract Thermal analysis of a solid-liquid phase using cooling curves at various compositions is a method used to obtain the eutectic composition and temperature of naphthalene-biphenyl. The XE was 0. 45 and the TE was 310. 3K these are slightly different from the theoretical values which are 0. 44 and 312K respectively. Results The cooling…
