Purpose- To observe different chemicals and their effects on each other.
What is making the color in a flame test? ~The amount of energy in a proton and the metal ion
What color of light is the lowest in energy? ~Red
What color of light is the highest in energy? ~Violet
What color of light is the highest frequency? ~Red
What color of light is the lowest frequency? ~Violet
In chemistry, what is a salt? ~An ionic compound (Na+1 CI+1)
How are electrons “excited”? When energy (Heat+light) is added and they move up a ground shell
What is a “ground state”?
When all electrons are at the lowest possible energy level In your own words, write a short explanation of how an electron absorbs energy and re-emits it as light and why different elements have different spectra. Electrons can be induced to absorb energy, resulting in an excited energy state. (Quantum Jump.) The energy determines the color, and the light forms when electrons loose energy
What professionals would use this type of information? Firemen, Firework designers, Chemists, Scientists, etc
Why is the Statue of Liberty green? The amount of copper in the Statue of Liberty could make 30 million pennies! When the statue was originally assembled, it was a dull brown color, reflecting the natural color of its copper plates. Over the next 30 years, though, it slowly turned to the green color you see today. https://www.google.com/search?client=safari&rls=en&q=why+is+the+statue+of+liberty+green&ie=UTF-8&oe=UTF-8&safe=active Suppose you were a fire fighter and you were called to a chemical plant fire. Upon arriving, you see a bright violet/purple flame. What chemical would you know was burning? Control Methanol, CH4O
Using the info in your data table, design a fireworks display that transitions between four different colors. Explain what is happening My firework display would be green, pink, purple, and blue, meaning I'd use (in order); Potassium Chloride, Control Methanol, Borax, and Calcium Chloride.
Research some information on the origin of fireworks. Explain how they are made, what chemicals are used, what colors they burn, and their uses Aerial fireworks are usually manufactured as a shell that is made up of four parts. The container consists of pasted paper. The fuse allows the shell to reach the desired altitude before exploding. A bursting charge made of black powder (like a firecracker) is at the center of the shell. Chemicals used: Aluminum, Antimony, Barium, Calcium, Carbon, Chlorine, CopperIron, Lithium, Magnesium, Oxygen Phosphorus, Potassium, Sodium, Sulfur, Strontium, Titanium, Zinc. https://www.google.com/search?client=safari&rls=en&q=how+are+fireworks+made&ie=UTF-8&oe=UTF-8&safe=active http://chemistry.about.com/od/fireworkspyrotechnics/a/fireworkelement.htm
