Making Connections: Chemistry Assignment By. Sujay Sukumar 5. a) When analyzing the graph‚ a relationship between the hydrocarbon chain of the alkane and its corresponding boiling point can certainly be noticed. There is a increasing correlation which can be explained using the theory that as each hydrocarbon chain gets bigger‚ there are more atoms and thus more electrons which contributes to higher dispersion forces and therefore a higher boiling point which is clearly seen through the graph.

The Chemistry of Lipids Experiment #8 Objective To observe the solubility of lipids in polar and nonpolar solvents and to compare saturated and unsaturated fats in their chemical reaction with bromine. The percent fat in a food will be determined by extraction of the fat and weighing it. Introduction Lipids‚ by definition‚ are natural substances that do not mix with water but dissolve in organic solvents. There are several classes of lipids‚ including: fatty acids‚ waxes‚ triacylglycerols

Philippine Coffee - Barako (Coffea arabica & Coffea canephora or robusta) About Coffee Coffee has two main varieties or species‚ Coffea arabica and Coffea canephora or more popularly known as Robusta. Arabica (Coffea arabica) was originally cultivated in the Arabian Peninsula‚ hence its name. While Robusta (Coffea canephora) is grown in many regions where Arabica would not grow but Robusta has less flavor and contains more caffeine than the Arabica. However‚ Robusta contains more antioxidants
