ChE 101 Lab Exercise 4 05 December 2012 Materials Balance (Non-reacting Systems) THR/WRU 1. A 40-mol-% aqueous ethanol solution is to be distilled into two streams: a distillate with 98% ethanol and a side stream with 60%. 98% of the alcohol in the feed is to be recovered in these two products; only 2% goes into the bottoms. If the bottoms product contains 2% ethanol‚ calculate the amount of the different streams per 1000 kmol of feed stream. Given: Recovery = 98% of ethanol in

Determining the Molar Mass of an Unknown Solute by Freezing Point Depression Introduction: Colligative properties of solutions are only influenced by the concentration of solute particles and are independent of the nature of the solute. Some examples of colligative properties are boiling point elevation‚ vapor pressure lowering‚ and freezing point lowering (depression) (Brown‚ 542). For a substance to freeze‚ the kinetic energy of the particles must be low enough for the

BIOSENSORS ADVANCED BIOREPORTER TECHNOLOGIES FOR TARGETED SENSING OF CHEMICAL AND BIOLOGICAL AGENTS Steven Ripp and Gary S. Sayler Introduction Bioreporters refer to intact‚ living microbial cells that have been genetically engineered to produce a measurable signal in response to a specific chemical or physical agent in their environment (Figure 1). Bioreporters contain two essential genetic elements‚ a promoter gene and a reporter gene. The promoter gene is turned on (transcribed) when the

Introduction: Stillnox has many different names‚ Zolpidem‚ Ambiem and Lorex to name a few. Zolpidem is a prescription drug used for treating insomnia‚ it works quickly (within 15 minutes) and the effects last for around 3 hours (PubChem‚ 2016). As Stillnox is extremely effective in helping insomnia sufferers fall asleep a Stillnox dependence occurs and can often lead to addiction. In extreme circumstances death from overdose of Stillnox has and can occur. This can affect society in a number of different
