For the unknown flame crystals‚ it may NH4+ because the colors that appeared are very similar to the crystals. Next‚ chemicals have to be heated in the flame for the color to emit because heat adds energy to the substance making the electrons more excited‚ allowing for the electrons to transition faster. Then‚ the method of lighting the

Introduction PBDE’s are chemicals used extensively in several consumer products around the world. They are mainly flame-retardants and are found in consumer goods such as electrical equipment‚ construction materials‚ coatings‚ textiles and polyurethane foam (furniture padding) http://clinmedres.org/content/1/4/281.short. Similar in structure to polychlorinated biphenyls (PCBs)‚ PBDEs resist degradation in the environment. PBDEs were typically produced commercially at three different levels of bromination;

Calcium Carbonate due to results from the Flame Test and Anion I Test. Throughout our lab days‚ my friends would help me determine various odors and colors of the substances which allowed me to confirm my answer. Also‚ I looked select test results up on the internet to see if they matched my observations. On our first lab day‚ I received my bottle and noticed a white precipitate in the bottom therefore‚ my unknown was insoluble. I started my testing with the Flame Test and did not evaporate my unknown

PORTERS The threat of potential new entrants (High) High capital required to enter into mobile industry which needed large investment on technology‚ distribution‚ service outlets and plant. Difficulty for customers in switching cost‚ when they are satisfied with their current product as well as difficultly for new entrants to have product differentiation because customers had already familiar with those established mobile companies‚ therefore new entrants have to spend a lot on branding and

C.R.W Flames Just keep calm and stay low. I cant breathe. There’s too much smoke. I have to find my little brother. Mom says that she couldn’t find him. I can feel my throat closing up. I can’t quit looking. Maybe he is still asleep in his bed. Wait! I hear someone calling me. Henry? It does not sound like my little brothers voice. It must be my mother calling from outside. Ouch‚ what was that? I just kneeled on a comb. That must mean I’m in the bathroom now. Everything looks different in

One thing that Robert Gray has mastered is leaving no detail big or small out. Flames and Dangling Wires is a poem that effectively conveys the effects of the human’s materialistic demands on the world. Robert Gray shows what life will inevitably be if our actions and attitudes do not change through the somewhat disturbing images that he renders The idea of a fog like shield is used to show that the increase production of waste is hiding us from the true reality of our actions.

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
