This explanation can be demonstrated in table 3 also because the results of the reactions demonstrates that chloride reacted more by the color of the product compared to the color of chloride in the mineral oil. Also it also demonstrates that iodine is the weakest oxidizing agent because the results show that iodide didn’t change much from the color that it showed in the mineral oil. In example 6 we have shown the activity series for the halogens used in this
Be sure that the strips are much narrower and slightly taller than the drinking glasses. 2. In the center the strips, about 3 cm from one end, place a dot of the marker to be tested. The dots should be about 0.2 cm in diameter and dark enough to be clearly visible. 3.
One major consideration when planning cable duct and trays is the bending radius, the bends must have smooth curves. Although conduits can still be used inside the building, so when a cable is pulled into a conduit, the conduit’s bending radius must be larger than the cable’s minimum bending radius for loaded conditions. Direct burial, aerial and blown fiber installations. Most common is the use of direct burial installations for long cross-country installations. The cables are plowed in or buried in
6. Zinc Sheet: a rectangular, thin, sheet like metal, gray/silver. 6 5 4 3 2 1 * Solubility of solid iodine; 1. Solid iodine in 1 mL of water is slightly soluble, because the solution turns into a light brown/yellow color. However majority of the solid Iodine was left at the bottom of the test tube; which leads to the conclusion that it’s not reactive on water.
In all the separation was pretty successful in getting Rf values for the three fractions, and the two compounds. Between the benzil and benzoin compounds, it was found that benzoin is the most polar. Benzoin was the most polar because it traveled the least amount of distance on the TLC plate. Conclusion: The results of this lab was that three different Rf values were calculated for the three fractions, and to measure their polarity from most to least polar. Fractions 1,2, and 3 were all separated by column/flash chromatography and their purities were measured with the TLC plate.
Determine the ratio of the heat loss from a 1m3 cylindrical tank of optimum dimensions (that is, the dimensions of the cylindrical tank for which the heat loss is a minimum) to the heat loss from a cubic tank with the same volume. Which tank design do you recommend as being more “environmentally friendly”? Remember: Vcylinder= πr2h SA cylinder= 2πr2+
A) is neutralized by water B) is surrounded by water molecules C) reacts and forms a covalent bond to water D) aggregates with other molecules or ions to form a micelle in water Answer: B Page Ref: Section 3 11 9) Which would you expect to be most soluble in water? A) I B) II C) III D) IV Answer: A Page Ref: Section 3 10) Solutes diffuse more slowly in cytoplasm than in water because of A) the higher viscosity of water. B) the higher heat of vaporization of water. C) the presence of many crowded molecules in the cytoplasm. D) the absence of charged molecules inside cells.
As the result of this, it can explain why the distance of fluorine in hexane is longer (1.3 cm) than the one in toluene (0.5 cm) and due to less non polar toluene has. Fluorenone can dissolve a little in toluene and slightly distance (1.0 cm) under toluene instead of does not move any more under hexane (0
In the experiment, toluene was alkylated with 2-chloropropane to synthesize isomers of isopropyltoluene in 47% yield, weighing 2.66g. The final product had a purity of 91.8% while the appearance was a colourless clear liquid with a strong odour. The results suggest that although the product yield was low, the experimental design led to the production of isopropyltoluene in high purity. REFERENCES 1. Smith R, McKee J, Zanger M.

From experimental results, it is found that the ratio of funnel speed to flow area of mortar with a fixed amount of super plasticizer is almost constant, independent of the water powder ratio. The higher the amount of super plasticizer the lower is the ratio of funnel speed to flow area. This ratio is proposed as an index for the effect of super plasticizer on mortar flowability and viscosity from the viewpoint of achieving self-compatibility. This index is useful to evaluate the amount of super plasticizer for proper flowability and viscosity of mortar. Sukumar and Nagamani (2010) reported the relation between superplasticizer dosage and fly ash content existed in SCC mixes with 8-52% fly ash, slump flow of 742-793 mm and w/p ratio of 0.31-0.34.
