2. The gas phase catalytic oxidation of benzene reactor model and evaluation of the parametric sensitivity To illustrate the parametric sensitivity analysis, the case of gaseous phase catalytic oxidation of benzene to maleic anhydride was considered (Lupușor et al., 1981). The multi-tubular reactor (heat exchanger type) with the fixed bed catalyst inside a small diameter tubes (under 3 -4 cm) is continously cooled by molten salt mixture (nitrates and nitrites mixture; Maria , 2007). The raw…

reactions as whole. It also helped us determine how the amounts of sodium carbonate and calcium chloride affect the chemical reaction made: calcium carbonate. Introduction: This lab was to show the relationship between reactants and products. In this case, we used calcium chloride and sodium carbonate. This made a chemical reaction and eventually formed calcium carbonate. The goal of this lab was to determine how the amounts of sodium carbonate and calcium chloride change or affect the…

the reaction of sodium carbonate and calcium chloride dihydrate (the dihydrate must be included with the molar mass calculation)? Predictions: Predict the mass of sodium carbonate and calcium chloride dihydrate that will be required to produce 1.90 grams of calcium carbonate: Therefore, the predicted mass of sodium carbonate is 2.0 grams and the predicted mass of calcium chloride dihydrate is 2.8 grams. Materials: 2 Beakers (150 mL) Calcium chloride Sodium carbonate…

In experiment 2, we observed that the reaction of halogenoalkanes with aqueous alkali and water which contains dissolved silver nitrate. Halogenoalkanes are alkanes which have one or more hydrogen atoms replaced by halogen atoms such as fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) which are the elements in group 7 in periodic table. Halogenoalkanes have the general formula, RX, whereby R is an alkyl or substituted alkyl group and X is any of the halogen atom. Besides, halogenoalkanes…

unknown, we needed to have a set amount of the unknown salt, and then add measured amounts of water to determine the minimum amount needed to completely dissolve the salt. The cation test told whether the unknown contained barium, calcium, potassium, sodium, strontium, lithium, copper, or magnesium. Given a chart of the colors that each burn, lit the unknown on fire with a bunsen burner and compared the flame color with the colors in the chart. In order to identify the anion, we needed to…

Even so, its nutritional value is essentially the same as ordinary table salt and sea salt. All three consist almost entirely of sodium chloride. Sodium is important for health in that it has benefits such as helping your muscles and nerves to function properly. As with table salt, it is important to limit your consumption of rock salt. Diets that are high in sodium are associated with high blood pressure and heart disease. Salt is thought to benefit health in a number of ways, such…

Salt, NaCl, is a chemical compound made of sodium and chloride which has been very important to humans for many years. Salt’s ability to preserve food was the most important aspect for many civilizations. It helped eliminate the problem of only being able to eat seasonal food. Also since salt was rather hard to obtain many people used it as a form of currency. Today, However salt is almost universally accessible, while being cheap and often iodized.…

and the flask was attached to a ring stand to rest on top of a magnetic stirrer device. In consistent drops, 0.63 mL of glacial acetic was added and the reaction had a pH of 2, which was measured with pH indicator paper. Then, 0.50 mL of 10% w/v sodium hypochlorite (NaOCl) solution was added, and the reagents were reacted for three minutes. Shortly after, 5.13 mL of 10% w/v NaOCl was added incrementally with a Pasteur pipet for about ten minutes. A thermocouple was periodically placed on the…

Introduction Finally, a warm day after a harsh winter, so what can you expect, all the ice/snow melting and flowing into our drains or into our grass, soil, and plants (Gould, 2013). Alongside with the ice/snow melting away into our environments so is that salt that was previously used to treat the roads (Gould, 2013). Roadside vegetation can become injured or die to due to the runoff from the treated pavements (Gould, 2013). The salt used for treated pavements is usually chloride-based and is…

The purpose of this lab is to understand the effect that dissolved impurities will have on the freezing point of a mixture and what additive will affect the the freezing point the most. The freezing point of a liquid is, the point of a substance when the temperature of the solid and the liquid is equal. When water freezes the water molecules become organized and come closer together forming crystal particles of ice.When a solute (like salt) and a solvent (like water) mix together the salt…
