Post-Lab Questions 1. Using the information provided in the Introduction and your observations from Part 1‚ hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint. a. Aqueous Sodium Hydroxide—NaOH (aq) is a very strong base‚ which will completely disassociate into Na+ and OH- ions‚ which would make it a very strong electrolyte. Chemical reaction of the disassociation of Sodium Hydroxide: NaOH (aq)Na+ (aq)+ OH-(aq)

Using Freezing-Point Depression to Find Molecular Weight Abstract: In this lab‚ the purpose was to use the freezing point depression method to determine the molecular weight of aspirin. This was done by determining the freezing of t-butanol and that of a t-butanol and aspirin solution; then finding the molality of the solution‚ and moles of aspirin. In the results of the experiment‚ the molar mass was found to be 192.2 g/mol‚ which differed from the established value of 180.2 g/mol by 6.7% error

attachment and sale of the properties of the judgment-debtor. Since‚ a decree holder does not by virtue of the judgment‚ get a right to the property‚ he cannot get the right by way of filing a suit but by attachment and sale in execution. While through the process of attachment the court informs the world that the property so ordered to be attached is “in its view” and “no existing rights and liabilities should be altered”; through the process of sale of the properties of the judgment-debtor‚ the

2.2.3 Purposes of Real Property Valuation There are five elements of property value: Production: productivity is the way of enhancing or hindering capacity for valuation Utility: Utility is the ability to arouse desire for its possession or use. Scarcity: The object must be relatively scarce to satisfy the demand. Demand: There must be a need and ability to purchase. Transferability: It must be possible to transfer good title with ease (Donald A. Corb‚ JD and Richard A. Giovangelo‚ 2013-14)

Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast
