The Empty Pot (China) BY royal proclamation‚ the Emperor of China announced a contest to decide the next heir to the throne. The Emperor was old and had no son‚ and because he had been a plant-lover for years‚ he declared that any boy who wanted to be king should come to the palace to receive one royal seed. Whichever boy could show the best results within six months would win the contest and become the next to wear the crown. You can imagine the excitement! Every

Our Iceberg is Melting is a story of penguins who are very comfortable with their present existence until a curious penguin named Fred discovered one day as result of curiosity that their iceberg was melting. The iceberg was the foundation of the penguins’ existence and without it they would perish. Fred had the courage to inform Alice who is a member of the Leadership Council about condition of the iceberg. Alice was a penguin who got things done and would listen to Fred. Fred had the opportunity

Lab #1: Melting Points of Organic Compounds Report Form May 15‚ 2014 1. A “Melting Point Range” refers to the range of temperature at which a solid melts into its liquid state. 2. Pure compounds have narrow or ‘sharp’ melting point ranges‚ 1°C or less if the compound is very pure. A less pure compound exhibits a broader melting point range‚ between 3°C to 10°C as well as a depressed or lower range. 3. Crushing the sample allows for greater surface area-to-volume ratio of the powder‚ this

Melting Point Determination and Thermometer Calibration Lab Background: The melting point of a substance‚ a solid in this case‚ signifies the temperature at which the first crystal starts to melt until the temperature at which the last crystal disappears is reached. That being said‚ melting points are expressed in ranges‚ am organic compound will have a sharp range depending on the purity of the compound. Impurity of an organic substance will register an abnormal melting point based on its

Crystallization and Melting Points Organic Chemistry 221 9/19/2012 Intro/Purpose: The purpose of this lab was to use crystallization to separate a compound from a solvent and be able to choose the best solvent to do so. Then identify an unknown and verify purity using melting points. Solubility contributes to crystallization; because a solute has lower solubility at lower temperatures‚ which makes the solvent separate from the solution as a solid. This process is important to understand because

Pol Pot‚ leader of the radical Khmer Rouge in Cambodia stands as one of the most savage mass murderers in the history of the world. In an attempt to create a utopian agrarian society‚ Pol Pot eliminated all opponents to his totalitarian regime. Up to 2‚000‚000 Cambodians lost their lives to this cleansing‚ the equivalent of more than twenty-five percent of the entire population. The world looks on in horror at the aftermath of this destruction. Pol Pot‚ or Saloth Sar‚ was born on May 19‚ 1925‚ in
