* Formula One racing is one of the most revered sports in the world. In the auto-racing world it is second to none in class‚ prestige‚ history‚ and skill. The level of competition is immense and the window of entry is miniscule. This brings up one question: (what is the question?) Formula One racing’s history dates back to the 1950s when racecars were simple front engine‚ drum brake cars. Compared to the cars of today‚ they are dinosaurs‚ but they were the best of their time and a wonder to many

Chemical Proportionality (Carbonate and Hydrochloric Acid) Introduction: The purpose of this experiment is what happens when a solid substance‚ a metal carbonate is added slowly to a solution of an acid. We are finding methods of determining acid concentration. For us to balance certain equations‚ we will use a stoichiometry. For this experiment‚ we will need to set up the ratio and finding the concentration of HCI. Procedure: • Grab 4 different beakers. • Add a small amount of sodium carbonate

Determination of an Equilibrium Constant Abstract: In this experiment‚ two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium‚ LeChatlier’s Principle‚ Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration

Sean Dowling Julia Phaltankar Mrs. Oakes Chemistry w/ Algebra 10/G February 18‚ 2015 Determining Empirical Formula Lab Introduction: One can find an empirical formula by taking a sample of a compound and dividing the number of moles of one element in the compound by the number of moles of another element in the compound to form a small wholenumber formula. For example‚ in a sample of a made up compound of oxygen and lead‚ one mole of lead has a molar mass of 207.2 g/mole‚ and oxygen

Chemical Periodicity Engr. Imelda Galera De La Salle University-Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT Chemical periodicity was demonstrated using different samples of elements from Group IA‚ IIA and IVA. These samples are: Li2CO3‚ Na2CO3‚ K2CO3‚ MgCO3‚ CaCO3‚ BaCO3‚ Carbon‚ Tin‚ Silicon and Lead. Each sample was placed in a test tube‚ (one sample and one test tube) and the physical color‚ appearance and state was defined. Water was used to test the solubility of the element
