31 Introduction- Magnesium is a silvery-white alkaline metal found represent by the atomic number of 12. This experiment involves combining Magnesium with Oxygen which is a gas represented by the chemical element 8. The word equation for the result of this experiment is Magnesium + Oxygen= Magnesium Oxide. The equation is Mg + O =MgO Definitions Word Definitions Mass Number The Mass number is the amount of Protons and Neutrons in the Nucleus. Atomic Number The amount of protons found

Introduction: This experiment was conducted to see which colored light pill bugs would prefer more out of red‚ blue‚ yellow‚ and green lights. If pill bugs went to the green and yellow lights more than the blue and red lights‚ then this means they like brighter lights more than gloomier lights. For the experimental group‚ the colors used were blue‚ red‚ yellow‚ and green. The controlled group was the middle chamber. It got regular light from the classroom. The independent variable was four different

Was the Weimar Republic doomed from the start? It had a promising beginning: A constitution guaranteeing federal rights‚ seven year presidential terms and proportional representation was passed in Weimar on the 19th July 1919. This should have meant a good foundation for democracy and sound government. Article 48 stopped (in theory) the major politicians from arguing. It was supported by the Big 3 world Superpowers (Great Britain‚ USA and France). The Constitution meant that everyone as

One objective was to figure out if the burnt Mg ashes weigh more than the product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner

King Christian was different from other kings because he didn’t have a huge ego. He was able to sacrifice his position as king in order to save his people. I think he made the right decision because he save many of his people. Trying to fight against the Nazi’s in a direct military conflict had no chance to succeed. However‚ the people were able to continue to fight secretively through a resistance movement. This was a more effective way for Denmark to fight the Nazi’s. It was clear that the

From 66 Experiments by Charles Bernstein‚ I chose experiment 23 to write a poem with each line filling in the blanks of "I used to be _____ but now I am ______." I chose this experiment because I am one who draws a lot of writing inspiration from personal experience and the instruction allows me to do that. However‚ it is not to say that it made it easier because it was challenge to reflect at my own life and dig deep into who I was and examine who I am now. At the start‚ I knew I have already

Gjulia Vokrri 02-15-2013 Abstract Alkenes can be produced by heating and dehydrating an alcohol in the presence of a strong acid. The purpose of this experiment was to synthesize cyclohexene by dehydration of cyclohexanol and to detect the presence of a double bond in the alkene. The dehydration reaction using distillation was performed using two acid catalysts‚ 85% phosphoric acid and sulfuric acid. Tests for unsaturation were performed
