Flame

by using the absorption of electromagnetic radiation by free atoms. A flame is created to atomize the sample. The solution is aspirated into the flame. Many of the atoms that are in the solution are at ground state. When a light at a specific wavelength is sent through the sample, the electrons will become excited. The absorbance of the sample is recorded and it is directly proportional to the amount of atoms that is in the flame (Marcel,…

I went back to sleep. I awake in pain, at around three in the morning. I go to the bathroom to get some medicine, when i again feel like i am being watched. Full of uneasiness, i head downstairs to eat the feelings away, like always. I hear a weak knock at the door, as if the knocker was afraid of breaking the door. I open the door and a hooded figure falls through the doorway, onto the floor. I try to help the person, and i ask if it is okay. When it doesn’t respond, i tap it on what i thought…

Proof of this was an element of burning salt and watching the flame. When cupric chloride was burned two out of three times it was turquoise color(Franks). However, all three times when strontium chloride was burned the flames shown red(Franks). Likewise, beryllium chloride and potassium chloride both burned the same color all three types; beryllium was a purple flame and potassium was a pink flame. Like cupric chloride, lithium chloride flame was a fuchsia color for only two types out of three.…

writing above to insert into the bubble because it is an ABAB rhyme scheme. An ABAB the rhyming alternates lines. The first and third rhyme with each other, and the second and fourth rhyme. I talked about how the dragon is attacking the city with his flames. Instead of calling it a dragon I called it a monster. I called it a monster because it is an imaginary creäture that is huge and frightening. The second stanza or line I talked about how the boy and his dog is in a helicopter being…

Identifying Unknown Substance. Examining the physical characteristics of the available compounds in the lab was how possible compounds were eliminated from any or further testing. Based on how the compounds physically looked, it was almost for certain that calcium chloride was the unknown compound. However, another compound was used to test as well (ammonium chloride) since relying only on physical characteristics alone would not allow for proper experimentation. The unknown ended up being…

water from the sullen and wrathful sinners. Heretic sinners are condemned to eternal life in tombs that are flaming with fire. I made the tombs and filled them with flames to symbolize their punishment. Around the tombs I chose to do more flames to represent that the sinners are condemned to eternity and cannot escape because flames are everywhere. I painted the bottom of the circle red and yellow. I done this so they would represent the heat given off by the…

name by Naomi Oreskes explores the unethical tactics used by several industries to market unsafe products and make profits. The main theme is climate change, but the movie investigates the business practices of various industries such as tobacco, flame retardant, and oil companies like Exon mobile. The story begins in the 1950 with a look at tobacco industry and their public relations campaign strategies that are designed to create doubt that cigarettes does not causes cancer. The public…

Readers’ Delight Students’ Reading Material 1. Fuel • Introduction to Fuel A fuel is a substance that has energy stored inside it. So, a substance that produces useful energy when it undergoes a chemical reaction is called as a fuel. Upon burning a fuel, a large amount of energy is released as heat. Fuels are used for various purposes such as cooking food, running vehicles, generating electricity etc. Coal, wood, petrol, diesel etc. are some common fuels. Thus, a fuel can be defined as a…

The image I chose, titled Anxiety, was created by Benjamin Koelewijn. The picture shows a nude woman with a burning scalp covering her body in different ways. The flames are burning a cloth on her head, and the cloth shields her eyes. Her face is nearly void of expression, and is smeared with oil, along with her shoulders, arms, chest, and torso. Her right hand clenches her left shoulder, and a blanket is draped between her arms. Her arms are covering her chest, she’s covered in oil, the right…

In the field of Microbiology, it is essential that the microorganisms being examined are seen clearly and distinctly under the microscope. Most specimen thrive in aqueous environments, therefore they are translucent and when mounted on a microscope the light passes through them making it impossible to see the specimen. Equally as important as this is that the viewer is aware of what type pf bacteria is being utilized. Both of these criteria in a lab are met with the use of a staining procedure…
