1. Place the 4 solutions in separate test tubes with about 2.5 mL in each. (NaF, NaCl, KBr, KI) Use a dropper or you can use a pipette. Add 1 Ml ( 20 drops) of 0.5 M Ca ( NO3h) to each test tubes. Observe…
Resource nationalism is largely perceived as developing countries phenomena, with Latin America and African resource-rich countries leading the way in terms of increasing government stakes in the extractive process, mainly through tax and royalty regimes. Nonetheless, resource-rich developed countries, notably Australia and Canada have increasingly adopted resource nationalist policies that include the blocking of Chinese investments and the tightening of fiscal regimes in the extractive sectors. The failure of BHP Billiton’s bid for PotashCorp in November 2010 blamed by the company’s chairman, Jac Nasser, on a global trend towards “protectionism or nationalism” arguably represents an escalation of the politics of resource nationalism in the developed world.…

1. Why did Allen’s heart rate and blood pressure fall in this time of emergency (i.e. at a time when you’d expect just the opposite homeostatic response)? Pg. 969…
This case study describes what happens when a health district merges four laboratories into one unit due to external driving forces for change, primarily the government funding cuts. Although the intention was to develop one centralized, efficient, and high volume centre, the inattention to the ‘people issues’ and the cultural differences of the work units results in chaos. The recently hired laboratory manager, Claude, has implemented several stopgap measures intended to address the work load issues resulting from high turnover levels and sick leave usage. However, these measures do not improve the morale and performance problems of the laboratory. Time is running out for Claude as his supervisor gives him an ultimatum to ‘clean house or else.’…

In the late 1800’s there was tension between the North and South. It soon got worse when Abraham Lincoln won the election of 1860. Soon after he won the election the southern states seceded from the Union, and then started the Civil War. The reason the Union won the Civil War was because of the technological advances such as weapons, railroads, and creation of the telegraph. Weapons were helped by advances in technology because it gave shooting more distance and velocity, “minie ball” bullets, and advancements in rifles.…

The purpose of this lab is to identify unknown ions in a solution by using a type of chemical reaction called precipitate reactions. The key to finding which ions are present in a solution is to form a precipitate which makes the ions “come out” in a reaction (McNeil, 2013-2014). Water is used in these experiments to act as a solvent. Since water is a polar molecule, the slightly positive and negative charges will sometimes pull apart molecules and surround them based on charges. In other words, water can dissolve ionic compounds and create an aqueous (aq) solution. This lab uses no quantitative analysis, but is entirely based on qualitative analysis which is the observed result instead…

When a slurry of the resin in water is poured into a vertical glass or plastic column equipped with a porous plug at the bottom to trap the resin and excess water is allow to flow out, the column becomes filled with water soaked resin, as shown in Figure 1.…
In the first part of this experiment, the student was presented with 7 unique and unidentified bottles of solutions labeled A-G and was expected to be able to analyze the 7 solutions through trial and error and mixing them with one another.…
Chromatography refers to a set of laboratory methods used in separating as well as purifying biomolecules. A variety of chromatography techniques exist, and all depend on the interaction between a stationary and a mobile state. Two types of chromatography methods were examined in this investigation. First, ion-exchange chromatography was used. This method separates ions and polar molecules based on their affinity to the ion exchanger [2]. Specifically, cation-exchange chromatography was performed, a technique that uses a negatively charged ion exchange resin with an affinity for molecules with a net positive charge. Anion-exchange chromatography relies on the same principal, but with a positively charged ion exchange resin with an affinity…
