Laboratory 3. Empirical Formula Of An Oxide This experiment will demonstrate the law of conservation of mass‚ and more specifically‚ how the law can be used to experimentally determine the empirical formula of our intended product‚ magnesium oxide. In this experiment we will learn how to: 1. heat a sample in a crucible with a Bunsen burner. 2. use the method of weight by difference to determine mass quantities. 3. convert grams to moles. 4. determine the simplest ratio between two

Laboratory Report: Flame Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength
