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

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

The features of spoken language often changes depending on a number of factors; one of which includes the location and of whom they are speaking with. In the popular TV series‚ The Wire‚ the audience is introduced to the first transcript set in a deprived area of Baltimore where many of the street jargon slang and social accent is prominent. In comparison‚ language that is used in a courtroom of the second transcript is far more formal than street language. In the first transcript the purpose of
