Paddle Pop Stick 2 Co 3 Flame
663 wordsExperiments to determine the identity of metals by examining the colour of flame when samples of that metal are heated. The aim of this experiment was to find out whether different metals had different reactions when subjected to the flame of the Bunsen burner. This might then allow the classification and identification of certain metals if they have their own reactions, which will be different coloured flames for this experiment. It was hard for me to predict what would occur during the experim...

Hydrogen Peroxide Test Tube
320 wordsHow does this Enzyme effect on this Biochemical Reaction? Purpose: The purpose of this lab was to discover the effects that certain enzymes have on chemical reactions. Were studying organic chemistry specifically, cells and proteins. The building blocks for proteins are enzymes and what better way to understand how they work than to watch them catalyze a reaction. Hypothesis: None really, just that we predict reactions in all of the test tubes except in test tube four where you sprinkle sand int...

Manganese Element Earth
253 wordsHi, I am Manganese. I am an element discovered in 1774 by the Swedish chemist Johan Gottlieb Game. My symbol was devised, coincidentally, by taking the first and third letters in the word manganese. My atomic number is 25, my atomic mass is 54. 938, and my density is 7. 2. I melt at 1245? C and then in turn I boil at 1962? C. A fact about my ionization energy currently escapes me, but I do have some uses and interesting facts in the rest of the paper. I am used as an antioxidant nutrient, I acti...
