Analysis of an Unknown Mixture Performed: 2/13/14 Submitted: 3/3/14 Abstract: The purpose of this experiment was to separate and identify the two unknown compounds. The sample used was 105 and it contain 2-propanol and 2-heptanone. IR spectrums were taken of the contents of the second and sixth test tubes and showed the presence of an OH functional group and a small amount of ketone in test tube two and a large presence of ketone in test tube six. The average boiling points of the test tubes

Individual solid particles are characterised by their size‚ shape‚ and density. 1.1 Particle shape The shape of an individual particle is expressed in terms of the sphericity F s‚ which is independent of particle size. The sphericity of a particle is the ratio of the surface-volume ratio of a sphere with equal volume as the particle and the surface-volume ratio of the particle. For a spherical particle of diameter D p‚ F s =1; for a non-spherical particle‚ the sphericity is defined as Dp:

If only they knew what was in the mystery mixture. After a long time of experimenting‚ the 8th grade scientist came to a decision on how they are going to figure what is in the mystery mixture. Once they started‚ they all looked at its physical properties. Then the scientists thought about the chemical reactions‚ and how that will help the claim the scientists had. More than half of the scientists thought it was baking soda and citric acid. When combining baking soda and citric acid together‚ the

Laboratory 2 DRYING OF SOLIDS (Vacuum Tray Dryer) A Final Report Submitted to Engr. Luis K. Cabatingan Instructor‚ ChE 512L By Madeja‚ Rayam John D. July 31‚ 2012 1. Introduction Drying generally means the removal of relatively small amounts of liquid from materials. It is also defined as the transfer of liquid from a wet solid into an unsaturated gas phase. The goal of most drying operations is not only to separate a volatile liquid‚ but also to produce a dry solid of a desirable size

“There should be a wall of separation between church and state” I believe in the wall of separation as originally intended‚ as a reference describing our First Amendment right of freedoms not prescribed by government. The term “wall of separation” first came about with Jefferson’s response letter to the Danbury Association in 1802. The letter was in regards to why he would not declare national days of fasting and thanksgiving as done by Washington and Adams before him. In the letter Jefferson brings

Running head: SOLID STATE DRIVE VERSUS HARD DISK DRIVE Solid State Drive versus Hard Disk Drive Information Erntzo Jean-Gilles Western International University Abstract Technology is advancing at an unstoppably fast and furious pace. The IT world has known changes in a lightning fast velocity that it is hard to predict its future. Things that could only be thought of ten years ago become out-of-date technology today.

designed with equal ruling powers‚ or separation of powers unlike a monarchy‚ where only one is making the decisions for all subjects of the kingdom. In addition‚ the separation of powers allows for equal power to be dispersed between the three branches of government. America was established by the founding fathers to create a government with equally divided powers. When President George Washington was chosen to become the very first president of the United States‚ America had just begun to introduce

5 Reasons Why Solid State Drives are Safer Solid State Drives is the new technology behind storage capacity be it in computers‚ PCs‚ and pretty much anything that utilizes 0’s and 1’s‚ nowadays. Compared to HDD (Hard Disk Drives)‚ they surpass this old age technology at every aspect‚ from performance to life expectancy. However‚ SSDs are more expensive too in that respect‚ but considering all the advantages‚ the hefty price tag is a small price to pay‚ especially if you have data that is so crucial

Constitutional Separation of Powers The Constitution of the United States vests the power of the government in three coequal branches -- the executive‚ legislative‚ and judicial branches -- and establishes a system of checks and balances so that no one branch can become too powerful. This separation of powers helps to allow each of the three branches the ability to work together to protect the individual rights of both free citizens and offenders while also preventing a single branch from taking
