GRAVIMETRIC ANALYSIS OF A CHLORIDE SALT (2013) Report By: ____________ Lab Partner: ___________ Group: CHEM 1001 Tuesday AM‚ Group H Purpose: This lab was conducted in order to determine the content of chloride in an unknown salt‚ using gravimetric analysis. Theory: The salt chloride content is easy to find because it is slightly soluble‚ making it possible to turn it into a precipitate. A precipitate reaction can be done using silver

Yurop Shrestha Economics Thesis CAPM vs. APT: An Empirical Analysis Introduction The Capital Asset Pricing Model (CAPM)‚ was first developed by William Sharpe (1964)‚ and later extended and clarified by John Lintner (1965) and Fischer Black (1972). Four decades after the birth of this model‚ CAPM is still accepted as an appropriate technique for evaluating financial assets and retains an important place in both academic scholars and finance practitioners. It is used to estimate cost of capital

relation to the mass of the crystalline structure. This water that is trapped inside the hydrated solid structure is called water of crystallization or water of hydration. A salt with associated water of crystallization is known as a hydrate. The formula of a hydrated salt is written as the number of moles of water present in one mole of crystalline structure. Deliquescent materials are substances that absorb water from the atmosphere and eventually become hydrated. These materials‚ usually salts

developing a theory‚ theorists must construct their theory so that it can be judged by this certain criteria. This criteria is made out of: 1.) empirical validity‚ 2.) its logical consistency‚ 3.) scope‚ and parsimony‚ 4.) testability as well as 5.) The usefulness and 6.) the policy implications (Akers and Sellers‚ 5). It is important for a theory to possess empirical validity because without it‚ theorist would be unable to determine whether said theory could be accepted or dissolved with the evidence that

between the corrected number of moles and grams of urea and the amount of urea used originally used in the experiment‚ so the ammonium chloride will be primarily compared to the corrected amount of urea to make sure that the amount of solvent is equal. Graph 1 and 5 and Data Table 2 show that the mass of solutes were overall very similar: 8.735 grams of ammonium chloride and 8.99 grams of urea. Overall‚ this experiment proved that the freezing point depression is a colligative property that depends on

amount of ATP the seed can generate in order to grow‚ the temperature of the environment and the amount of sunlight the seed receives (Ghaderi-Far et al.‚ 2010). The purpose of this study was to observe the effect of different concentrations of sodium chloride have on the germination of lettuce seeds‚ Lactuca sativa. A study done by Katembe et al.‚ (1998) stated that an increase in salt solution in the environment of the seed will slow down water imbibition‚ therefore‚ preventing germination and root growth

Capital Assed Pricing Model‚ widely known as CAPM is essentially an equilibrium relationship between expected return and risk of an asset and that is used in the pricing of risky securities. CAPM is the result of William Sharpe (1964) and John Lintner (1965). Sharpe took the Nobel prize in 1990 for the asset pricing theory. CAPM is used for a range of applications and purposes‚ these include estimating the cost of equity capitals for firms as well as evaluating the performance of managed portfolios
