Commercial Aspirin Tablet Analysis Tuesday Evening Intro: The purpose of this lab was to analyze commercial aspirin tablets. To do so‚ the percent acetylsalicyclic acid (active ingredient) in tablets using acid-base titration was determined‚ the percent acetylsalicyclic acid in tablets by formation of a colored iron(III)-salicylate complex was determined using spectrometry‚ and then the percents from each process was compared. Acetylsalicylic acid is produced when salicylic acid and acetic

* The puritans believed that the bible was god’s true law. They believed that secular goveners are accountable to god to protect and reward virtue‚ including “true religion” and to punish wrongdoers. * Their values were both individual and corporate conformity to the teaching of the bible‚ with moral purity pursued both down to the smallest detail as well as ecclesiastical. * The puritans defined truth in the ways of god’s true laws. They often said “Let god be true‚ and every man a liar

Experiment I: Thermochemistry Background: Thermochemistry is the branch of chemistry that focuses on the studies of chemical reactions or physical changes and heat associated with chemical reactions. According to the first law of thermodynamics‚ energy cannot be created or destroyed but it can be converted from one form into another and/or transferred between different atoms‚ molecules‚ or substances. In general‚ energy can be classified into two categories: kinetic and potential. Kinetic energy

Why we have laws- The law is a legal set of rules that the government and courts have made for everyone to follow. Without laws‚ confusion and chaos would occur. In extreme cases of conflict‚ a state of anarchy would develop. The person with the most strength will start to dominate and the weak and helpless would suffer. However‚ when laws are enforced‚ a sense of order is created resulting in a society where everyone can live peacefully. Why laws change-? Societies’ perceptions have changed over

Before S/MIME‚ administrators used a widely accepted e-mail protocol to transfer messages‚ Simple Mail Transfer Protocol (SMTP)‚ which was inherently less secure. With S/MIME‚ administrators now have an e-mail option that helps provide greater security than SMTP‚ enabling widespread and secure e-mail connectivity.

Thermodynamics- Enthalpy of Reaction and Hess’s Law December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant

The English word “law” refers to limits upon various forms of behavior. Some laws are descriptive: they simply describe how people‚ or even natural phenomena‚ usually behave. An example is the rather consistent law of gravity; another is the less consistent laws of economics. Other laws are prescriptive - they prescribe how people ought to behave. For example‚ the speed limits imposed upon drivers that prescribe how fast we should drive. They rarely describe how fast we actually do drive‚ of course

Problem 1 Issue1 Is the La Rochelle website‚ including the slogan‚ protected by copyright law? Law Copyright law protects text‚ images and other forms of expression. The requirements for protection are as follows: (1) The creation is a ‘work’ or ‘subject matter other than works’; (2) The creation is original; (3)The creation is expressed in a material form. Application The slogan is not a ‘work’ or ‘subject matter’ because Single words‚ names‚ titles‚ slogans are too short to be protected

CHAPTER 5 GASES AND THE KINETICMOLECULAR THEORY 5.1 Plan: Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant‚ but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated‚ but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant‚ but the volume of

Heat of Neutralization Lab Objective: The objective of this lab was to measure‚ using a calorimeter‚ the energy changes accompanying neutralization reactions. Background: Chemical changes are always accompanied by a change in energy‚ typically as heat. If the reaction releases heat (ΔH < 0) then the reaction is exothermic. If the reaction absorbs heat (ΔH > 0) then the reaction is endothermic. The quantity of heat is measured experimentally by having the reaction take place in an insulated container called a
