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.

Mark Zuckerberg On the afternoon of Nov. 16‚ 2010‚ Mark Zuckerberg was leading a meeting in the Aquarium‚ one of Facebook’s conference rooms‚ so named because it’s in the middle of a huge work space and has glass walls on three sides so everybody can see in. Conference rooms are a big deal at Facebook because they’re the only places anybody has any privacy at all‚ even the bare minimum of privacy the Aquarium gets you. Otherwise the space is open plan: no cubicles‚ no offices‚ no walls‚ just a

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

It is ‘thiazolidine-2‚4-dione’ and not thiohydantoins as the reaction product of monosubstituted thioureas and chloroacetylchloride a a a a a The reaction products of monosubstituted phenylthioureas with chloroacetylchloride in a polyethylene glycol (PEG-400) medium and K2 CO3 as base/catalyst at an elevated temperature are exclusively thiazolidine-2‚4-diones and not thiohydantoins as has been reported. The core unit thiazolidine-2‚4-dione is essentially derived from chloroacetylchloride

Unlike the brain where a person can continue to be “alive” without any electrical activity‚ without a heartbeat‚ a person cannot live. The average person doesn’t ever think about how or why their hearts lub dub every minute of every day until they die. For someone whose heart doesn’t beat properly‚ the lub dub is a frequent worry. Brandon England is one of those people
