Determination of the heat of Combustion of Biodiesel Using Bomb Calorimetry Abstract: In this experiment‚ biodiesel fuel was synthesized from vegetable oil. Biodiesel is considered “green” and better for the environment because it is biodegradable. The heat of combustion was then determined using a bomb calorimeter. Introduction: Petroleum is the largest single source of energy consumed by the world’s population‚ exceeding coal‚ natural gas‚ nuclear‚ hydro‚ and renewables (3). It is predicted that

Name CH 204 DateExperiment 3: Atomic Spectroscopy Introduction The purpose of the atomic spectroscopy lab experiment was to investigate the relationship between visible light‚ which is the visibly observable range of electromagnetic radiation and the change in energy levels of an element. The line spectrum that was seen in the spectroscope was the evidence of excited atoms emitting electrons and radiating a spectrum of light as it moved from a higher energy state back down to a lower energy level

Conclusions The purpose of this experiment was to find the relationship between a substance’s specific heat and its atomic weight. In the lab‚ the substances with the higher atomic weights had less specific heat. From this‚ we can conclude that specific heat and atomic weight have an inverse relationship‚ meaning as one decreases the other increases. The reason for this is because if atoms are small‚ or light‚ they have the ability to pack tightly together‚ leaving almost no space between them

Bomb Calorimeter What is a Bomb Calorimeter? In calorimetry‚ a bomb calorimeter is a piece of equipment used to measure the heat fluctuation of a reaction’s system‚ the changes in physical properties and the thermal capacity. How does a Bomb Calorimeter works? A calorimeter is basically used for measuring the heat of fuels as it burns at a specific temperature in order to obtain the heat energy values. The samples of fuel used can either be solid or liquid but not gas. The calorimeters is estimated

DBQ:5 George Washington faced many challenges during his presidency. Some of these challenges were difficulty of setting up a new government‚ domestic difficulties‚ and foreign affairs. He had a hard eight years of presidency but he mostly resolved all the problems. One of his challenges was setting up a new government. This was hard because people just revolted against their last form of government. They revolted against their last government because taxation was a major issue. Collecting

Weiss‚ Tania APUSH-3 Mr. Hafter 9-7-14 DBQ In the 1600’s‚ the Puritans migrated to the Americas using their more Christian and traditional values to influence the economical‚ political‚ and social development of the New England colonies. The Puritans traveled out of a desire to create a more “pure” and more Christian society‚ not of primarily economic interests. The Puritan’s idea of what God’s indication of a perfect humanity made a lasting impression on New England. The region’s economic

The First & Only-Atomic Bomb The atomic bomb‚ also known as the atom bomb or fission bomb‚ a weapon whose explosive power originates from the fission of atomic nuclei‚ a reaction in which an atomic nucleus splits in two. When the nucleus of a heavy atom‚ such as the element uranium-235‚ which is what the atom bomb is made out of‚ is split‚ a certain amount of mass disappears and an equivalent amount of energy is released. This was expressed by the equation E=mc2 (energy = mass times the speed of

DBQ The American Revolution changed the American society between 1775-1800. The areas in the American society that were changed were economical‚ political‚ and social. ways. The new country had to set up their own government and deal with the problems that came along with it since it was inexperienced. That brought problems between the society and political side. Native Americans and women had their own concerns and opinions. Therefore‚ the American Revolution changed the American Society. ‘
