Specifically explain how the colors in the flame tests are produced. You must include the following terms in your answer: energy, energy levels, electrons.…
Also, potassium would give off a light purple color when lit, making it simple to identify against the other substances.…
As the substance heats up, the electrons gain energy from the flame to move to a higher level of energy. At this higher energy level, the electrons become unstable and start to come back down to the “ground state” (lower energy levels). As this happens, the electrons in the substance release a certain amount of energy, which we see as a color…
The Triangle Fire was a horrible event which caused deaths of workers who were working at the Triangle Shirtwaist Factory. This factory was a sweatshop. A sweatshop was a place where people worked for long hours with low pay, and they worked in very poor conditions. People who worked here were there for the money that they needed. They were immigrants, young women, and children. They may have been doing this to support their family. Poor conditions and a few other things caused many deaths in this fire. Also there was a policy from the government called the laissez faire. This policy said that the government can't interfere with the business operations. This was favored by the business because then they could do whatever they wanted to. The business could have horrible conditions for the workers…
Unknown 1 was Sodium and Unknown 2 was Potassium. I compared and contrasted each of the flame colors. Then, I observed that the elements and flame colors were the same as I initially saw.…
In this lab, we will record the flame test color of several metals by making solutions of salts, or ionic compounds, of those metals then igniting them with a match.…
I. Purpose: To observe the colors produced when compounds are introduced into a flame and the electrons become excited. To estimate the wavelength of light produced, then calculate the frequency and energy of the light…
The title of the documentary I watched is “Triangle Fire” it was made February 28, 2011 about the massive Triangle Shirtwaist Fire of 1911 that killed 146 people. The thesis of this film is mainly taking a look into the working lives of immigrants in the early 1900’s. The filmmaker’s agenda was apparent in this film and it was to expose the working conditions, and lives of these workers at the time to ensure the viewer would know the corruption that was at hand with the private industry of American factories. This film wanted to convey the message that the working conditions in factories in these times were unacceptable and they led to the biggest work related tragedy in that city to date. This film is accurate because it covers all the historical evidence that’s needed to show its viewers what the working condition were that…
In this experiment we are trying to observe this amazing phenomenon. Heating up different elements using a flame, we are able to see the change in states and the emitted photons. In the process we will try to answer questions such as: how does the amount of energy absorbed by electrons affect the color of light produced? What does the light produced tell us about the energy of the emitted photon? What has more energy, a photon that takes one big step, or photons that take many steps? Our objective is to observe the unique color of light emitted by each element, and determine the…
The neon bulb was red and the bright line spectra began with many red lines followed by red-orange lines which was followed by smaller amount of yellow lines. Then, there was a gap afterwhich came green lines followed by blue lines. The last light source we tested, argon, had a purple bulb with a line spectra that appeared to be solely made up of violet lines. During the second part of the experiment, we vaporized each metallic ion in flames and collected the resulting color of the flame. With this information, we consulted the chart that shows the representative wavelength and wavelength region in nanometers of different colors to make an educated guess on the possible wavelength of each collected flame color. For the lithium ion we observed a red colored flame (690 nm wavelength), the sodium ion had a yellow orange flame (597 nm), the potassium ion had a salmon pink flame (420 nm), the calcium ion a light orange flame (607 nm), the strontium ion a blood orange flame (678 nm), the barium ion a light green flame (550 nm), the copper ion a green flame flame (593 nm), and the unknown ion with a red flame (690 nm) very similar to that of the lithium…
3. Why do the chemicals have to be heated in the flame before the coloured light is emitted?…
Deepak Chopra once said, “The masculine energy was about survival. The male was the hunter who risked his life and had to be in the fight-flight mode.” When pertaining to survival, the main character in “To Build a Fire” by Jack London failed to follow three main steps in Laurence Gonzales’ nonfiction trade book, “Deep Survival.” The main character failed to stay calm, to think, analyze, and plan, and to never give up during his trek through the pure, untrampled white snow.…
Inside each firework are small packets filled with chemicals, mainly metal salts and metal oxides, which react to produce an array of colors. When heated, the atoms of each element in the mix absorb energy causing its electrons to rearrange from their lowest energy state to a higher excited state. As the electrons plummet back down to their lower energy state the excess energy gets emitted as light.…
In “To Build a Fire” by Jack London, the main character, also known as “the man”, is the protagonist. The protagonist is “the central character in a literary work and the character who initiates the main action of the story.” (Kennedy 2080) The man is a dynamic character whose lack of instinct, thoughtlessness and determination leads him to his own death.…
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 a fog. It’s so disorienting. Why can’t I crawl any faster! Just a few more feet until my brother’s bedroom. I can’t open his door; it must be locked. Ill have to kick it down, but I don’t think I’m strong enough. Oh how I wish the firemen would get…
