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,…

The objective of the lab was to determine the densities of known and unknown metal solids and liquids. For the liquids, initially, an Electronic Scale was placed onto Work Bench, and it was zeroed. An empty 50 mL Graduated Cylinder was placed onto the scale, weighing 54.00 grams. In increments of 10 mL. Until the volume was 30.00 Ml, 10.00 mL of water was poured into the Graduated Cylinder. In between each increase of 10.00 mL, the total volume and mass were recorded. For the known metals, the…

Danika Ng CHEM 1252 L Exp 12: Thermodynamic Analysis of Chemical Equilibria INTRODUCTION The reaction being done with borax and HCl is an acid base reaction. The K constant expression of the reaction is Kc = [Na^+][B4O7^-2]. A titration is needed for this experiment because when a strong acid with a known concentration is added to a weak base, the unknown concentration of the weak base can be found, which can then find the moles of the weak base, which can then find the Kc. The first law of…

CHAPTER 2 LITERATURE REVIEW 2.1 Effect of Binder and Plasticizers on the Gel Viscosity, Membrane Morphology and Pore Size According to M.R. Othman [7] the result of addition of PVA in Boehmite sol during peptization on the viscosity, coating time, pore size and BET surface area is presented in Table I,II,III, and IV. PVA was prepared by dissolving 2, 4, 6 and 8g of PVA powder into 100mL de-ionized distilled water. PVA with different concentration in the sol give a of characteristics viscosity…

Abstract. The theoretical treatment of the equilibrium structure of the derivatives was based on the DFT method using the functional B3LYP with the base 6-311 ++ G (d, p). To distinguish the molecular electrostatic potential surface (MESP), we used the principle of HSAB (Hard Soft Acid and Base), in order to have the centers of activity of a molecule and the effects of substitution on the systems of pyrazolooxazine. These have anti-inflammatory activities. In our work, we have applied methods of…

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.

Experiment 1. Title: How does the amount of baking soda affect its reaction with vinegar? Aim: To find out how different amounts of baking soda (soda bicarbonate) affect the length of its chemical reaction with vinegar (acetic acid). Hypothesis: If the amount of baking soda is increased then the length of its reaction with vinegar will increase because there will be more soda bicarbonate for the acetic acid to react with. Equipment:  Baking Soda  Vinegar  5 glasses  Safety glasses …

NIMOTOP INJECTION Nimodipine 0.02% solution contains the following excipients: Ethanol 96%, Macrogol 400, sodium citrate, citric acid, Water for Injections Ph. Eur. These excipients consist of properties that aim towards the proper functionality of Nimotop. They consist of inherent stabilities that cause little or no effect in the stability of the drug and they do not have any acute or chronic toxicity. The excipients are also added into the Nimodipine 0.02% solution to enhance the biological…

.1 Material Composition The raw material mentioned above has to be taken into an appropriate ratio to compound the batch sample. Generally, to test the property change in the polymer by the influence of a filler/additive is done by processing several batches with different but gradual loading of the filler/additive. Here, we have to test the properties of nano Calcium Carbonate in the polymer matrix of polypropylene. For this, 12 batches are prepared by using the different size of filler by…
