Chemistry 1 February 3‚ 2014 Harvesting CaCo2 in a precipitate reaction results in less grams desired amount (2 grams) Abstract: The objective of this experiment was to synthesize 2.00 grams of CaCo2 for a hypothetical manufacturing company using the two least detrimental (in regards to health and the environment) and least expensive chemicals possible through a precipitate reaction. A precipitate reaction happens when cations and anions of certain aqueous solutions react and combine forming

The purpose of the lab was to construct a graph of sugar content versus density for 5 sugar solutions and to determine the sugar content of the 5 beverages using graphical analysis. The hypothesis was that if a beverage has more sugar‚ then it will be more dense. The results of the lab included the densities of all the solutions and beverages‚ which was then graphed. Then‚ using the graph‚ the sugar content for the beverages was determined and a rank of the beverages was created. From lowest sugar

Angelina Mass-Valderrama CHM1032 summer ‘12 Graphing and Estimating Formal Lab Report Introduction: Today scientists put acquired data into a form of a graph. This said graph is designed to help make predictions and furthermore‚ study and understand the experiment and its contents at hand. The Graphing and Estimating lab involves just that. The lab is designed to collect data from several tests involving burn time of a candle. Oxygen‚ O2‚ is a kind of gas. A lot of the air we breathe

Coulomb’s Law Purpose: The purpose of this lab was to demonstrate that the force between two stationary charges is directly proportional to the product of the charges and inversely to the square of the distance between them. Coulomb’s law tells us that the force between two charges depends (1) linearly on the strength of each charge‚ and (2) inversely on the square of the distance between them. Mathematically we would write this as . Procedures Part1 Begin by removing the right side

In "The Piece of String‚" a short story by Guy De Maupassant‚ the main character is a peasant named Maitre Hauchecome. Maitre Hauchecome was a frugal‚ innocent and offended man. A poor man from Breaute‚ Maitre Hauchecome was a thrifty Norman who believed that everything with a purpose should be picked up and saved. His outlook on life ended up costing him his reputation. An adjective that could be used to describe him would be frugal. Maitre Hauchecome was not wasteful or lavish. He spent his money

Laboratory Techniques and Measurements (adapted from Labpaq Version 09.1.06 by Peter Jeschofnig‚ Ph.D.) Experiment Summary You will have the opportunity to learn how to conduct measurements in mass‚ volume‚ and density using scales and common laboratory equipment. Review the safety materials and wear goggles when working with chemicals. Read the entire exercise before you begin. Take time to organize the materials you will need and set aside a safe workspace in which to complete the exercise

stilling materials at the bottom to provide a constant head of water to be discharged through a bellmouth entry to the flow visualisation pipe. Flow through this pipe is regulated using a control valve at the discharge end. The water flow rate through the pipe can be measured using the volumetric tank (or measuring cylinder) of a Hydraulics Bench. Velocity of the water can therefore be determined to allow for the calculation of Reynolds’ number. A dye injection system is installed on top of the header

in a time of catastrophe is when I uncovered a strong inspiration. The composition of Adagio for Strings became the primary source of my emotional outlet. This twentieth century piece was performed in 1938—just one year before the start of World War II. America was still recovering from the Great Depression and was pushed to one of the world’s most disparaging global conflicts. Adagio for Strings was some sort of a prophesy displaying the destruction in which the war would create. The need for
