Guns‚ Germs‚ and Steel Europe’s geographic position was a key influence on its development. Not only was Europe close to the Fertile Crescent‚ but it also it contained climates and habitats that animals and crops could adapt to. In the 16th century‚ livestock animals that came from the Fertile Crescent dominated European farms. These animals included the cow‚ sheep‚ goat‚ horse‚ and many others. They served as a source of meat‚ milk‚ wool‚ manure‚ and muscle power. They transformed the productivity

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

professor. This sparked Jared Diamond to answer this question by turning back the clocks of time to an era where everyone lived the same. This is the beginnings of Diamond’s ground breaking and heartwarming three- part documentary called “Guns‚ Germs‚ and Steel.” This documentary goes deep into history and answers the main question of‚ “How did our worlds become so different?” Jared Diamond takes on the challenge most philosophers wouldn’t dare try of dividing the haves and have-nots of the world
