Introduction In this lab‚ the density of 20 glass beads were determined using two different methods and the results were compared to see how close the values were to each other. In first method the volume of each individual bead was measured using the diameter of each bead‚ along with the mass. In the second method the beads we treated as a whole unit. The total mass was measured and volume was measured based on the amount of water that was displaced in a graduated cylinder. Then‚ the beads

Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment

Fahrenheit 9/11‚ is a documentary directed by Michael Moore. It all starts with the elections of the year 2000‚ with George W. Bush‚ Republican and Al Gore‚ Democrat. As they finished counting the votes all news channels gave Al Gore as winner‚ but friends and political allies of George W. Bush at Fox News Channel declared Bush the winner and so all the news retracted themselves and did the same as Fox. It then suggests the voting controversy in Florida as electoral fraud. Even do the majority of

In the lab‚ the purpose was to standardize a KMnO4 solution than using it to evaluate how close a H2O2’s concentration was to its labeled concentration. In this lab‚ it was decided to compare the concentration of new Publix brand hydrogen peroxide to an old sample of the same solution. From the data collected in the first part by titrating a solution of FeSO4*7H2O with the KMnO4 solution‚ it was determined that the concentration was .028M MnO4-. This was able to be done because a known amount of

11 was issued by Major-General Ulysses Grant. In 1862‚ the expulsion of all Jews was ordered in Southern areas. Grant believed a black market for cotton was being run by the Jews‚ and he issued the order in an effort to reduce corruption. Of course this is a violation of Constitutional rights‚ and a telegram was sent to Lincoln. General Orders No. 11 compared to Lincoln’s wartime actions show a pattern of civil liberties being

The more common name for these opportunistic Americans were industrialists. These people came on the rise as Robber Barons. What would become household names were simply paving their ways towards success in these days. This brand of people became a part of American culture‚ forever changing it and embellishing their names within it‚ such as Rockefeller‚ Standford

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

_______________________________________ ABSTRACT The experiment aimed to determine the equilibrium constant Keq of the formation of Fe(SCN)2+ from Fe3+ and SCN- in the equation Fe3+(aq) + SCN-(aq) ⇌ Fe(SCN)2+(aq)‚ through spectrophotometric analysis. Acidified solutions (using 0.1 M HCl) of FeCl3 and KSCN were prepared for the calibration of the UV-Vis spectrophotometer (using standard solutions) and the determination of Keq of the Fe(SCN)2+ formation (solutions with unknown concentrations)

An astronomer has a goal to discover and understand the nature of objects in our universe. Astronomers analyze and interpret the information obtained in order to make accurate models of these objects using instruments that collect‚ record‚ disperse and magnify the light that celestial objects give off. In this laboratory I learned how to measure the altitudes of stars using a quadrant. A quadrant is a quarter of a circle that has been divided into 90 degrees. I also learned how to find the angular
