Crispus Attucks

Crispus Attucks was born in 1723. Since he was a slave was not able to identify exactly where and when. He was a slave who worked on a big plantation in Framingham, Massachusetts (“Crispus Attucks,” Sweet search) His whole life he dreamt of himself being free. Then one he ran away to sea and got a job as a sailor for 20 years. He was finally free(“Crispus Attucks,” Wikipedia). He had heard that there was a problem down in Boston and went to see what was going on and saw sailors and workers screaming and yelling for freedom from the British. Then the Boston “Bloody” Massacre had broke out and Crispus Attucks was the first one to die that day, March 5, 1770 (“History,” Crispus Attucks). Crispus Attucks was important to history because he started off his life to being a slave (“Crispus Attucks,” Sweet search).Then ran away to sea and found a job to be a sailor for the next 20 years (“American Revolution: Crispus Attucks,” Thinkquest). And ever since he had died at the Boston Massacre he was very important to history. From that day forth he was known as the African-American hero because of how he never gave up (“Crispus Attucks,” Wikipedia). My inspiration for the float was his life that seemed so short but long. He didn’t really play a very important part of history but died for something that was very important to history, The Boston “Bloody” Massacre (“American Revolution: Crispus Attucks,” Thinkquest). The designs I chose in my float were stuff

Unknown Concentration

The objective of this lab was to find the concentration of iron in a solution with an unknown concentration. Through the use of the Beer-Lambert Law and spectrophotometry, one can find the absorbance of solutions with known concentrations of iron and create a calibration curve that can be used find the concentration of the unknown solution, which was calculated to being 10.5ppm Fe. This value is somewhat precise due to its relative standard deviation of 1.65%, and the errors were kept to a minimum…

Determining The Molar Mass Of An Unknown Liquid And Unknown Solid

The freezing point experiment was carried out to determine the molar mass of an unknown liquid and an unknown solid. The unknown liquid was #22 and the unknown solid was #26. To determine the molar masses of the unknowns, the freezing point depression was first found by first obtaining the initial temperature of the solution and then obtaining the lowest temperature the solution reached. The freezing point of the solution minus the freezing point of water equaled the freezing point depression. Using…

Unknown Lab Report

Identification of Three Unknowns Leah Bacon December 10, 2014 Chemistry 3020 M/W 1:25 - 4:25 William DeBenedetti Abstract Molecular structure can be determined by Fourier Transform infrared spectroscopy [IR, herein] by accurately identifying residues. IR is extremely sensitive to molecular structure because it measures the change in a molecule’s dipole moment due to vibrations caused by light absorbance. In this study, a variety of IR techniques were used to identify the composition of two unknowns by comparing…
