Investigating if dissimilar sized candles have the capability of drinking equivalent quantity of water. Aim: The drinking candle science experiment is quite enthralling, as when performed, you'll observe a burning candle drinking up all the water kept beneath it due to the behaviour of the atmospheric pressure. The aim of this experiment is to investigate if unlike sized candles have the capability of drinking the same amount of water. Hypothesis: With all the information given on different…

CaBr2 is an ionic compound, because the second element is a non-metal so it will form an ionic compound. The next step in naming an ionic compound, is to name each component as if they were ions. The first component is a cation so you leave the name alone. The second component is an anion, so you change the ending of bromine to "-ide" and it’s becomes bromide. The last step is to combine the names so, CaBr2 becomes Calcium bromide. The first element of the formula NBr₃ is nitrogen a nonmetal,…

Physical properties of PHB: PHB physical properties similar to polypropylene. However, PHB is perfectly isotactic and does not include any chain branching like, for instance, PE. During processing, it flows easily. It is insoluble in water and soluble in chloroform and other chlorinated hydrocarbons. It exhibits good barrier properties against oxygen and compared to other biopolymers. It possesses better physical properties than polypropylene for food packaging applications.

Plant Material Collection Fully grown whole plants of Tribulus terrestris Linn. were collected from different localities of Chennai, Tamilnadu. The fruits were separated out from the plants and washed in running tap water to remove adhering dirt and soil particles and dried first under shade in room temperature and secondly in a hot-air oven for complete drying at 50-60˚C. The dried fruits were made into coarse powder by grinding and stored in labelled bottles for further study and…

This experiments goal was to successfully produce ZnI2 by using Zinc Sulfate (Heptahydrate) and Barium Iodide Dehydrate, which Jessica and I did with acceptable success. The definition of acceptable success for this experiment is measured by how close our percent yield was close to the ranges provided (0-2% being considered excellent precision and etc). Our percent yield was 92 % meaning that it was an acceptable, but not exactly as close to what we wanted it to be. In order to try and figure…

of Sodium Chloride, being that it is not Hygroscopic, Efflorescent or Deliquescent. Thus, based on this experiment solely, it is not ensured that the salt is Sodium Chloride as 3 other salts share this…

two-part experiment meant to have us practice our skills and then use those skills in actual data collection and analysis. In part one we used a sample of sodium saccharinate combined with a sample of a metal halide salt, our group used copper(II) chloride. The combination of these two samples allowed for the synthesis of a metal complex. In part two of the experiment we used a procedure similar to part one in order to collect phosphorus out of a sample of fertilizer. This sample was then…

Day 2 of the experiment utilized Figure 5 to determine the metal cations present in an unknown solution #112. Each metal cation was confirmed or denied with ease, with the 2 cations present within Unknown #112 were correctly identified. Thus, Figure 5 was an accurate schematic to implement in this experiment. Following Figure 6, Unknown #112 was first added to HCl, forming a white, snow-like precipitate. The solution was decanted and separated to test the precipitate and solution, both of…

sufficient amount of time, it was carefully removed from the hot plate and left to cool down to room temperature. When the aqueous solution was cooled, one milliliter of saturated sodium chloride was added. By adding saturated sodium chloride, it attracts any water compounds that might react with caffeine. After sodium chloride was mixed in, 25 milliliters of ethyl acetate was used to separate the caffeine from the organic layer. Ethyl acetate is a polar compound that is used to attracted…

Can Salt Harm the Environment? For many years, traffic due to road construction has been viewed as different. Driving to work or travelling from place to another with daily traffic due to road construction is becoming a challenge to all American people. The main task for highway engineers in winter is keeping the roads clear and safe from snow. Engineers are obliged to choose construction materials that are environment friendly and ecofriendly. For decades, engineers used the road salt deicing…
