Chemistry Lab Report example: Chemistry Laboratory Report (Magnesium Oxide) INTRODUCTION: As we learned before on how to determine the empirical formula of a compound based on the test and also chemical analysis on it. Hence this experiment is mainly goes around with how to determine the empirical formula of Magnesium Oxide following various tight procedures in order to get the knowledge and apply it onto another compounds. We are investigating the empirical formula of Magnesium Oxide in this

‘The extent to which volcanic processes represent hazards depends on where and when they occur’. Discuss this statement A hazard can be defined as a situation that poses a threat to life‚ health‚ property or the environment. The severity and type of volcanic hazards that occur are mainly dependent on the type of magma. Volcanic processes can be split into two categories – primary hazards and secondary hazards. The primary hazards that can occur are pyroclastic flows‚ lava flows‚ tephra and poisonous

Determining Causes and Effects of Lake Huron Brian Jones Weber English Composition 5/19/2013 In today’s Ecosystem there are so many factors of cause and effect of pollution in any areas of the world. Pollutants affect the air that keeps us breathing‚ the animals that we hunt or fish‚ and even the water that we drink. Food‚ water‚ and oxygen are the most important things we need in order to survive a world full of life. With this being said Lake Huron and the other Great Lakes are being extremely

Determining causes and effects of not keeping a personal budget William E. David ENG115- English Composition Prof. Sandra McDonald March 10‚ 2015 It has been observed that most of the employees of Bank of America create individual budgets but do not keep a record of them. This is because most of the employees return to the bank for personal loans just two weeks after receiving their salaries. Due to this finding‚ the factory utilized financial analysts and decided to develop measures of controlling

performed to be able to determine the thickness of zinc on a piece of galvanized metal. It also aimed for the students to be introduced to the reactivates of metals with acids as well as for them to develop some feeling for the size of an atom. In determining the thickness of the zinc coating on the metal‚ students‚ knowing the density of zinc‚ calculated the area (A) of the metal covered with zinc and the mass of zinc removed after it is reacted with HCL‚ hydrochloric acid. Given the radius of a zinc

I. Abstract This experiment aimed to determine the composition of Ni2+- ethylenediamine (en) complexes through Continuous Variations method as well as the number of ligands (n values). This nondestructive method is preferred in determining the amount of complexes present which will also not disrupt the equilibria. 0.3M concentrations of nickel sulfate hexahydrate and ethylenediamene are mixed at certain stoichiometric ratios of 0.3‚ 0.4‚ 0.5‚ 0.6‚ 0.7‚ 0.8 and 0.9 to form several complexes.

Photoelectric Effect: Determining Planck’s Constant Friday‚ Section 006 TA: Yilikal Ayino John Greavu with Daniel Erickson & Kevin Haar January 31‚ 2014 PreLab Up until the eighteenth century‚ particle theories of light dominated physics‚ primarily due to the work of Isaac Newton. Thomas Young’s 1805 famous double-slit experiment‚ which showed that light mimics a wave‚ extinguished some of these early views. However‚ in 1887‚ Heinrich Hertz – who is‚ coincidentally‚ perhaps better known for definitively

Absorption Spectroscopy Abstract: Absorption spectroscopy validated Beer-Lambert’s Law‚ confirming Beer-Lambert’s Law was a successful method in determining the molar concentration of a sample within a composition that is unidentified. Absorption spectroscopy is used in order to determine the ε value; ε was calculated to be .0566. Introduction: The purpose of the Absorption Spectroscopy experiment is to evaluate the reliability and accuracy
