Emission Spectra & Flame Tests Intro The emission spectrum is used in modern chemistry to help further studies of wavelengths and the spectrum. When a metal in a compound reacts in a flame and produces a color‚ it helps to show the strongest color in the emission spectrum. The purpose of performing these operations on the flame was to see how different metals would react. Using a spectroscope‚ it is possible to observe the line emission spectrum produced by sunlight‚ artificial light‚ and

In this lab‚ we tested the effect of flame on different chemical solutions. In order to do this‚ we used a wooden stick soaked in a metal and nonmetal solution‚ hovered it over a bunsen burner‚ and recorded the color that the flame changed to. The seven solutions we tested were lithium chloride‚ strontium chloride‚ calcium chloride‚ sodium chloride‚ barium chloride‚ copper chloride‚ and potassium chloride. However‚ we had another four additional solutions‚ which had unknown chemical composition

the Tiger Mom” by Amy Chua‚ I was surprised how Chua shared in detail about her life journey as a parent and raising two children. This is a book about Amy Chua’s experiences in raising her two daughters‚ Sophia and Luisa (Lulu)‚ in what she believes is the “Chinese mother” style of parenting. She is quick to point out in the first chapter‚ entitled “The Chinese Mother‚” that she uses the term “loosely” as it would be ridiculous to try to assume that every mother from China is a like a tiger mom

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

decomposition and the combustion reaction. Coloured flames are seen in movies to represent something magical that is occurring such as a ritual. This is due to the vibrant colours used which communicate a sense of unusual yet visual appearance. chemistry concepts found in coloured flames are combustion reaction‚ electrons and atomic structures‚ molecules and particles. The following will pinpoint two special effects which are explosions and coloured flames and define the chemistry concepts found within
