Ionic order

Intermolecular Forces Intermolecular forces are the result of attractive or repulsive forces between atoms, molecules or ions, primarily as a result of electrostatic attractions; these forces act between discrete molecules. Intermolecular forces are weak forces but without them life as we know it would not be possible: water vapor would not condense into its liquid (or solid forms) if its molecules did not attract each other, and all matter, in fact, would exist as gases. The physical states…

either chemical elements or compounds. There are different observations that indicate a chemical reaction has taken place. Formation of precipitate, which is a solid formed in a chemical reaction. Precipitate can take place when solutions containing ionic compounds are mixed and an insoluble product forms. An example is mixing is mixing silver nitrate and sodium chloride in water, which will cause silver chloride to precipitate out of the solution as a solid. Color change can also indicate a…

the Doric order. The arches can be seen from the outside. When one walks in they are met by a series of barrel and groin vaults that run perpendicular to the outside arches. These vaults are the largest of the amphitheater simply because they are where the majority of the foot traffic will be. The second level has an Ionic Order as seen from the outside. It also has similar vaults like the first floor, but these get a little smaller and shorter. The third level has a Corinthian order with two…

above it. Like most of the architecture still standing at Priene, the temple was constructed from marble taken from a nearby quarry. This site’s main features included an open-air altar and a large temple of the Ionic order. The temple consisted of a propylon (an exterior gateway) with an Ionic porch and porticoes, a treasury, and a Doric stoa (covered walkway) with pedestal fountains. The altar was decorated with carved panels featuring female figures, likely Muses, and Apollo Kitharoidos, an…

favorably soluble in a certain solvent based on solubility characteristics of the desired compound. There are four factors that determine the solubility characteristic of a compound: pH, temperature of the solvent, pressure of the system, and ionic character of solute. Ionic character and pH were manipulated to increase solubility favorability of the compound in extraction solvent. In essence, pH is the easiest factor to manipulate because it merely involves using an aqueous acid or base as an…

the Colosseum was the perfect design for the masses to watch their entertainment. Another feature of the Colosseum that reappears in later designs is the three-tiered half columns that advance in order as they rise. The Palazzo Rucellai, in Florence, uses Doric order pilasters for the first tier, Ionic for the second, and Corinthian for the top tier (Figure 3). The key difference between the two designs is that the Palazzo Rucellai uses pilasters rather than columns and has a cornice to top the…

This lab looked at the different effects of an enzyme with concentration, pH, and temperature compared to the rate at which the enzyme works. The results showed a quick decrease when the temperature and pH has passed its most favorable conditions and or levels, but the concentration remains at the same levels throughout except pH6 and 40 degrees celsius. Both the pH and temperature had a steady increase in rate once the favorable conditions were being reached or are reached, but had a certain…

experiment is solubility. Solubility is the affinity for one solvent over the other. Liquids, or aqueous solutions, that may dissolve the same compound are commonly found to be miscible. By using liquid – liquid extraction a compound can transform into an ionic form, soluble in polar solvents (water), through acid-base reactions. Examples of organic molecules having ionizable functional groups which can be separated using acid-base reactions are as follows: The interaction…

Evaluating overall results compiled by practical investigations, the water sample showed very positive results with very minimal flaws in its purity. Observing the physical properties of the sample it had no turbidity and looked relevantly clear. Data shown here may be inaccurate due to many varied factors in the lab testing. Most of the testing heavily relied on the judgment of the human eye to compare charts colours possibly resulting in human error. A low 5 m/L’s was tested each time when…
