Project 1: Polymer Ball Vivian Kim General Chemistry 2045L Introduction Our assignment in this project was to create a bouncy ball for a company using polyvinyl alcohol (PVA)‚ polyvinyl acetate solid and sodium borate‚ by varying the ration of ingredients and to determine the best recipe for our bouncy ball. The company chose the materials because of their odorless and nontoxic properties. PVA is a water-soluble synthetic polymer and has adhesive properties

Unit 1 Lab 1 Data on Fixed Line vs. Cellular Debate June 16‚ 2014 Debate the Pros and Cons to having a purely cellular network vs. having a purely fixed line network Pro ’s: Cost: Most wireline phone companies charge more than what you ’d pay for most alternatives‚ and some are taxed more as well. There are some locations where getting new wired phoneservice is prohibitively expensive or even impossible. Long Distance and extra features like Call Waiting are normally included with alternative

LAB #1 - Assessment Worksheet 1) What does DACL stands for and what does it mean? DACL is a list of Access control entries; it defines access control for users and groups. 2) Why would you add permissions to a group instead of the individual? What policy definition do you think is required to support this type of access control implementation? When adding permissions to a group it makes it easier for a large organization and just set up the access for the departments‚ or job roles. Creating GPO

In Graph 1‚ each line of color represents a different level of pH added to the solution. When pH 9 was added‚ it produced the highest rate of reaction (the most oxygen was produced)‚ whereas when the more acidic pH 5 was added‚ the rate of reaction was much slower‚ and less efficient. The higher the oxygen evolved (gas produced)‚ the more reactions were being produced/higher rate of reaction. Different types of enzymes’ reaction proportions differ based on the pH being added. For example‚ intestinal

purpose of this lab experiment is that I will be able to decipher the difference between a chemical and physical change. I will be about to tell whether a chemical change has occurred during the experiment or if it was a physical change and I will be able to answer why it is either one. Procedure: In the lab experiment‚ I mixed different types of chemicals with different background to see if there was a chemical change‚ and also to see what type and why that change occurred.

Coordination Complexes of Cobalt Advanced Inorganic Chemistry Lab 02/27/2015 Abstract When the transition metal‚ cobalt‚ forms a complex involving a nitrate ion‚ the ligand has the ability to coordinate via N or O. The ability of the nitrate to attach via the N or O gives rise to the term‚ linkage isomers and can affect the functionality of the complex with other molecules. To explore structural differences between complexes‚ pentaaminechlorocobalt (III) chloride‚ pentaaminenitritocobalt (III)

Procedure and Observations: Using the procedure outlined in Appendix A of the Lab Manual‚ approximately equal samples of p-Nitrophenol and acetanilide‚ which are known to have the same melting range of 113-114 degrees Celcius‚ were taken and inserted into the melting point apparatus. The melting points of the compounds were noted
