In this week’s reflection video, I, learned about the weapon printing design done by the process of hydro-graphics. In the video a rifle stock is used with a Dip Wizard hydrographic kit to add a camouflage pattern. The Dip Wizard’s Kit just like other hydrographic kits uses a technique of applying a printed pattern such as; camouflage or any other pattern to a 3-dimensional object. This process goes by the terms; hydro-graphics, hydro-dipping, image transferring, immersion and water print…

Lab 9: Preparation of an Iron Oxalate Complex. POST-LAB: RESULTS AND DISCUSSION 1. Write a brief summary of your experiment. The experiment was conducted by creating a K3Fe(C2O4)33H2O solution using DI water, 3.501 g of iron (II) ammonium sulfate, H2C2O, K2C2O4, and H2O2. 5 ml of ethanol was dispensed within the solution to aid in the crystallization of the oxalate. The results of the experiment did not provided crystals of the oxalate rather crystals of impurities formed within the solution…

3-(4-acetylphenyl)-6-bromo-2-(4-chlorophenyl)quinazolin-4(3H)-one (2) Compound 1 ( 0.01 mol) fused with p-aminoacetophenone ( 0.01 mol) at 160 oC in an oil bath for 2 h. Crystallized from ethanol to give redish brown crystals of 2, m.p. 210oC in 80% yield. Analysis for C22H14BrClN2O2, Calcd.: % C, 58.24; H, 3.11; N, 6.17, Found: % C, 58.31; H, 3.17; N, 6.20, IR spectrum (KBr, cm-1) showed characteristic absorption bands at 3380 (C-H aromatic), 1710 (C=O of acetyl), at 1690 (C=O of…

Everybody has heard of paper maché, but not everyone knows of the much more useful alternative, paper maché clay. It’s simple to use, and easy to fill a space. It is much better than normal paper maché clay, even if it has it’s flaws. The benefits far outweigh the flaws, making it an extremely useful tool in making masks. Masks can be made from all kinds of material, but using paper maché clay is the easiest way to have the most artistic freedom. Paper maché clay can be messy, but so can paper…

Salt, NaCl, is a chemical compound made of sodium and chloride which has been very important to humans for many years. Salt’s ability to preserve food was the most important aspect for many civilizations. It helped eliminate the problem of only being able to eat seasonal food. Also since salt was rather hard to obtain many people used it as a form of currency. Today, However salt is almost universally accessible, while being cheap and often iodized.…

The Calorimetric Determination of Enthalpy and Entropy Changes of the Thermal Decomposition of Sodium Sulphate Decahydrate Abstract Sodium sulphate decahydrate thermally decomposes to anhydrous sodium sulphate at 50⁰ C and cools to form anhydrous sodium sulphate. Using Hess's Law the enthalpy and entropy changes of this process can be determined in order to deduce the spontaneity of the reaction. The transition temperature was determined by melting the hydrated crystals at 50⁰ C and allowing…

transported by red blood cells. Very discrete iron concentrations on a surface, such as 1 part per million, are enough to catalyze Luminol’s chemi-luminescence (react and cause it to glow). However, Luminol sensitivity is not blood-specific, and the compound also reacts with other substances for example, saliva, rust, potassium, permanganate, animal proteins, vegetable enzymes, etc. Therefore, Luminol tests [aren’t] [decisive] for blood and cannot be admitted for evidence in court. (“Lerner &…

Creating food: Before making the food, make sure to wash your hands thoroughly. After washing your hands, make sure to wipe down your station before using it. There are alcohol spray bottles throughout the lab. Spray it in your area and use the paper towels to wipe it down. Obtain a clean polystyrene vial and fill one eighth of the tube with dry food. The fly food was purchased from the Carolina Biological Supply company. Add about 9 ml of water to the dry food and gently roll the vial five…

As it can be seen the concentration of the phenol compounds decreased as the hydrogen peroxide increases. The presence of the anions decreases the rates of the phenolic compounds, the sulfates influence in a smaller degree. For phenol and 2-nitrophenol the difference in slope or degradation rates for chloride and sulfate are 0.71 and 0.55, and only 0.16 for 2-chlorophenol. The presence of chloride inhibits in greater proportion the formation of hydroxyl radicals than the sulfate , this can be…
