In the experiment‚ synthesis of copper compounds‚ the purpose was to recover the original amount of copper after series of chemical reactions. Then returning the copper back to its original form. The copper wire originally weighted 1.0099 g‚ but after the copper was transformed into Cu(OH)2 to CuO to CuSO4 and finally into Cu‚ the mass of the recovered copper was 1.1023g; the percent yield was 109%. Since the percent yield is more than 100%‚ an error must have occurred somewhere in the lab. A possible

Experiment 11: Synthesis of Dibenzalacetone by the Aldol condensation Introduction: The Aldol condensation reaction‚ under basic conditions‚ involves the nucleophilic addition of an enolate ion to another carbonyl group. The resulting product‚ a beta-hydroxy ketone or aldehyde‚ is called an aldol because it contains both and aldehyde group and the hydroxy group of alcohol. Condensations‚ including aldol condensation‚ combine two or more molecules‚ typically with a loss of a smaller molecule (including

Racism can be “defined as the hatred of one person by another or the belief that another person is less than human because of skin color‚ language‚ customs‚ place of birth or any factor that supposedly reveals the basic nature of that person. It has influenced wars‚ slavery‚ the formation of nations‚ and legal codes” (“What”). The face of racism over the past 50 years has changed but yet‚ some still stay the same. People made laws against racism and it is not as blunt anymore. But opinions and stereotypes

Preparation of Fruit Flavors (Pear) Abstract. In this experiment an assigned Ester is prepared‚ particularly n-Propanol. The Preparation was done via Fischer reaction. In this reaction‚ a reflux set-up is required. The reflux set-up was used in the liquid-liquid extraction. After adding an immiscible solution to the compound containing n-Propanol‚ the mixture now will have two layer: the Organic and Aqueous layer. The organic layer is the extract needed and its % yield is computed resulting to

“The Girl Who Was On Fire” Throughout history‚ one of the most prominent issues in society is the way gender plays its role. Women have always been cast aside as being the weaker one‚ being too emotional‚ while men‚ on the other hand‚ are the strong ones‚ who need no help and can do everything by themselves.
