The Dodge Nitro is a small SUV and is similar to the Jeep Liberty. Introduced in 2007‚ the five-passenger Nitro offered 2WD and 4WD configurations and two V-6 engine choices. Dodge discontinued the Nitro in 2011‚ ending a five-year model run. Dodge Nitro: 2007 to 2011 Based on the Jeep Liberty‚ the Dodge Nitro offered a few differences from its corporate cousin‚ including the front fascia‚ equipment offerings‚ and engine choices. Both models offer standard rear-wheel drive with part-time four-wheel

Lab 3: Bromination of Acetanilide CHEM 2110 Hassan Alsaleh 0525970 Due date :11/02/2015 Q1: To find the limiting reagent we need to find the number of moles of acetanilide‚ and the number of moles of Bromine. Mass of Acetanilide used = 0.67g Molar mass of Acetanilide = 135.16g/mol[1] Number of moles of Acetanilide = (0.67g) / (135.16g/mol) = 0‚005 mols Volume of Bromine = 0.25ml Density of Bromine = 3.103 g/ml[2] Mass of Bromine = (0.25ml) X (3.103g/ml) = 0.78g Molar mass of Bromine

nitritopentaamminecobalt(III) Chloride and nitropentaamminecobalt(III) Chloride. Their relative stability will be compared on standard conditions and the infrared spectroscopy of both the isomers will be obtained to analyze the characteristic absorption bands for the nitro and nitrito group. Yield for nitritopentamminecobalt(III) Chloride was obtained to be = 1.9221 g(73.24 %) and yield for nitropentamminecobalt(III) Chloride = 0.76 g(76 %) Introduction Linkage isomers may arise when one or more of the ligands can

Preparation of 4-bromoaniline Introduction Aromatic compounds tend to undergo electrophilic aromatic substitutions rather than addition reactions. Substitution of a new group for a hydrogen atom takes place via a resonance-stabilized carbocation. As the benzene ring is quite electron-rich‚ it almost always behaves as a nucleophile in a reaction which means the substitution on benzene occurs by the addition of an electrophile. Substituted benzenes tend to react at predictable positions. Alkyl groups

enjoy your free time. When it comes to RC cars‚ they can be powered with gas or an electrical battery. The gas powered RC cars can be a mixture of gas and oil‚ but other times‚ they are powered by nitro methane. You can purchase this from almost any online store. The reason a lot of people choose a nitro-power RC over electric is because they accelerate at higher speed‚ and they offer more power than their electrical counterpart. On the other hand‚ gas powered RC onroad cars are heavier‚ so they have
