After sublimation the weight of pure caffeine was .0027g‚ making the percent recovery of caffeine after sublimation .12%. The percent recovery of caffeine is less in the second half of the experiment because the crude caffeine had some impurities in it which were taken out by the process of sublimation. The average

rise to an amide. In this experiment‚ p-aminophenol‚ the amine‚ is treated with acetic anhydride to form acetaminophen‚ the amide. The crude acetaminophen was expected to be dark in color. This was due to the fact that the impurities were formed from oxidation of the starting phenol. The intensity of this was enough to impart color to the crude acetaminophen. Crude acetaminophen can be purified using the solid-liquid separation technique of ccrystallization where there is a transfer of the solute

A tanker’s deadweight is a measure of ship’s carrying capacity in tons. It includes both the weight of the cargo (in the case of ship’s carrying crude the cargo is the crude oil) and the weight of the fuel the tanker carries for her own propulsion purposes. Crude containers come in an enormous range of sizes like

Crude Birth Rates are devised by how many babies are born per one thousand people in one year. The CBR in Haiti is 25.63 babies per one thousand people. That means if you were to take one thousand people‚ there would be roughly 26 babies born in 2016 alone. However‚ the Crude Birth Rate in Hungary is far smaller than that of Haiti. Hungary only has a CBR of 9.20. That
