Fragrant Component of Cloves *Adri‚ Kiersten Jayne R.‚ Aguinaldo‚ Samuel Jr. Group 2 Department of Chemistry‚ College of Science University of Santo Tomas‚ España‚ Manila 1008 Abstract. In this experiment‚ the primary objective was to isolate eugenol from cloves. An amount of 30 grams of dried cloves and 300 mL of water was distilled over a flame for over 2 hours. The distillate underwent extraction with dichloromethane‚ water and sodium hydroxide. Concentrated hydrochloric acid was added

Conclusion and Evaluation Conclusion In our test we put six different sliced up potatoes chips in solutions. The solution was different concentration of salt and water‚ one was 5% sugar‚ one 10%‚ one 15%‚ one 20% and one 30% salt concentration. We measured the mass of the potatoes chip before and after we put it into the solution. To keep the experiment fair we only changed one variable which was the salt concentration. The results that we got showed the chip went up in mass for 0%

Carboxylic acids are compounds which contain a carboxyl group‚ -COOH group‚ where the -COOH group is attached either to a hydrogen atom or to an alkyl group. One of the example of carboxylic acid is benzoic acid( benzene carboxylic acid) which has a benzene connected to the carboxyl carboxyl group‚ -COOH group. It has a formula of C6H5COOH. The carbon atom of a carboxyl group has a high oxidation state. Therefore‚ that many of the chemical reactions used for their preparation are oxidations. In

Conclusion In this experiment‚ we measured the mass of 4 gasses; oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest

The separation of church and state is a very sensitive topic in today’s society. Most people see the phrase “separation of church and state” and think it is concrete‚ constitutional‚ proof that nothing religious should set foot in anything relating to government‚ but that is not always the case. The division of the church and the state was instead to prohibit the government from imposing or taking away any religious beliefs. Today’s laws concerning church and state relations are very strict.

The Separation of Powers exists to protect the natural rights of the people. It was created by Baron de Montesquieu during the Enlightenment and used in the Declaration of Independence by the Framers. The Separation of Powers is a division of government into three branches which prevents one branch from gaining too much power. The Separation of Powers‚ used by the Founding Fathers‚ is just as important today as when the written. The Separation of Powers is a system of Checks and Balances that acts
