Distillation Introduction: The recrystallization technique you learned last lab is a method for purifying solids. This week we will learn how to perform a distillation‚ a method for purifying liquids. Distillation is a common wet-chemical technique for separating organic compounds based on differences in boiling points. Upon heating a mixture of organic compounds‚ the more volatile compounds (those with the lowest boiling point) will vaporize first (i.e. be converted to gases)‚ leaving the higher-boiling

Whole Wheat Bread: A Whole lot of Lies As young impressionable children‚ parents and doctors always try to do what is best for us‚ including and possibly most importantly‚ the food we eat; what is healthier‚ what has less sugar‚ what has more nutritional value‚ etcetera…Even as adults‚ people tend to look for the product that has health benefits‚ such as the popular wheat bread. Wheat bread has always be thought to be the better choice over white bread‚ considering it has whole grains‚ fiber‚ oats

It was a wired heterogeneous mixture we could tell where the solvent and solute separated. She has no idea what it is so she brought the sample to class to show us. The purpose of the lab is for us to try and figure out what makes up this heterogeneous mixture‚ by making observations on the mixtures

Preparation It is manufactured by the calcium process: ~\mathrm{2Cl_2 + 2Ca(OH)_2\longrightarrow \ Ca(OCl)_2 + CaCl_2 + 2H_2O}. "Bleaching powder" is a mixture of calcium hypochlorite (Ca(OCl)2) and the basic chloride CaCl2‚ H2O with some slaked lime‚ Ca(OH)2. Properties Calcium hypochlorite is a yellow white solid which has a strong smell of chlorine. It is not highly soluble in water

Gatsby Essay In this extract from the novel “The Great Gatsby” by F. Scott Fitzgerald‚ the corruption and decay of the society is highlighted by the uses of various elements such as conflict‚ setting‚ characterisation and imagery. In first person‚ Nick shows his conflicting thoughts of what he thinks of the party. He feels the party and the people there are vulgar‚ yet appealing. This contradicts the way in which introduces himself – a non-judgemental who in most cases looks over the situation.

Long stands of double helical DNA can fit into the nucleus of a single cell because DNA is specially packaged through a series of compaction events to fit easily within cell nuclei. Even though the length of DNA per cell is about 100‚000 times as long as the cell itself‚ it only takes up only about 10 percent of the cell’s volume. The DNA molecule‚ in order to condense‚ wraps itself around groups of histone proteins‚ and then the chromatin folds back on it‚ nucelosomes pack together to create a compact
