Impurity

cooling the heated solution, the IMAF’s become stronger between the solute and solute recreates the lattice structure of the solid that was presented before heating but without impurities. The crystal structure will only allow the structures that fit, and segregate the ones that don’t; which in return help remove any impurities that were present in the…

is a “reference point.” We use reference points as bricks to build the prison of identity. In meditation, we allow that structure to collapse. When the roof falls in, we see the boundless sky. That is the vastness of nonduality, where purity and impurity are equally meaningless. We also must be willing to notice and let go of reference points when not meditating. That includes being willing to have our lamas poke fun at things we thought were very serious. nothing is…

determine its melting point, but not really enough to conduct an IR absorption spectrum, proven by the fact the “window” kept falling to pieces no matter what was done. The melting point was 70-90 degrees C, meaning there were some impurities in the sample. These impurities might be shown in the IR spectrum. An IR absorption spectrum was performed using another group’s sample. The IR had a peak at 3051 cm-1, from the alkene C-H stretch; at 2959 cm-1, 2905 cm-1, and 2852 cm-1 from the aliphatic…

The White Ribbon, by Michael Haneke, was released in 2009 in select theatres around the globe. Haneke’s film is an art piece that questions the society of Pre-World War I in their cultural actions. The White Ribbon reflects on the events of the town to take after the coming crisis in Germany through its utilization of mise-en-scene and motifs. Haneke employs a plethora of separate motifs to demonstrate the issues of the small village. One of the main motifs used is this film is the concept of…

DIstillation under Reduced Pressure STEAM DISTILLATION Steam distillation is a special type of distillation used for temperature sensitive materials like natural aromatic compounds which are insoluble in water, but volatile in steam. The non-volatile impurities are left behind in the flask. It once was a popular laboratory method for purification of organic compounds, but has become obsolete by vacuum distillation. Figure 6 Steam Distillation EXTRACTION WITH A SOLVENT The process of removing…

A group of men gang-raped a forty two-year-old Dalit women and burned her alive after she, her husband, and two sons had been held in captivity and tortured for eight days. This injustice occurred because the woman’s son fell in love with the torturer’s daughter, who happened to be of a higher caste. “The local police knew of the whereabouts of the Dalit family, but they did nothing because the rapists” came from a higher caste family (Mayell n.pag.). Even with decades of struggle to end…

Dofasco Acid STSE 1. Summarize this article in your own words. Include all the main points. (4) On September 7, a burst pipe at ArcelorMittal Dofasco sprayed hydrochloric acid mist through the Crown Point neighbourhood, which runs south of the plant. The Hamilton’s public health department is gathering information on this incident and its impact on the neighbourhood from the Ministry of Environment and ArcelorMittal. Evidence of the leak was witnessed across Crown Point neighbourhood. Residents…

the product at this step was 145.9-147.1°C, which is slightly below the 150 °C melting point of pure N-acetyl-p-toluidine but much higher than the 43°C melting point of the beginning p-toluidine. The slightly lower melting point could be caused by impurities in the sample. Along with melting point results, the IR spectrum shows a single N–H stretch peak at 1659.31 cm-1 showing the addition of a C=O and shows a peak at 3287.55 cm-1 which suggests an amide while the IR of sample 1 shows N–H…

the initial steelmaking process, prior to the continuous casting process, are included in the secondary steelmaking process. The tolerance levels of interstitial impurities and inclusions are lower in continuous casting than within ingot casting, and this has made secondary refining a critical component in order to control the impurities found in liquid…

benzoic acid. These compounds were separated by extraction and washing, and liquid-liquid extraction was specifically performed. Extraction is the process by which a compound of interest is selectively removed from impurities, and washing is the process by which unwanted products or impurities are selectively removed from the desired product. In liquid-liquid extraction, unknown B was dissolved sequentially into two immiscible liquids via a separatory funnel. The differences in solubility of…
