Flame Synthesis

Is Pyrokinesis Real? Is pyrokinesis scientifically possible? The rarity of these paranormal facts hinders their repetition and study by scientific methods.

I. Introduction: The reason we are able to observe different colors of light during the flame test is because the electrons move from their normal stable configuration, or ground state, to a different orbital and an excited state. When electrons are in an unstable state they need to get rid of energy in order to get back to their ground state. They do this through giving off light energy as photons. Depending on the element the photon will give off a certain color and move from its unstable, excited state back to a stable, ground state as they give off their energy through light.

In “To Build a Fire” by Jack London, the protagonist’s overconfidence causes him to eventually freeze to death. To begin with, the man tests the temperature of the air by spitting in the air. He shows confusion when the spittle crackles in the air, and not when it touches the ground. He admits that he does not know how cold it is, just that it is colder than usual. This detail reveals the man is inexperienced because he is a newcomer and has a lot of confidence that causes him to ignore all the warnings and advice given to him. His lack of experience shines through when he does not even know the temperature of the place. Not long after, the man feels the frostbite starting to dig into his fingers as he paused momentarily for a lunch break.

Furthermore, the combustion of propane is considered spontaneous because its ΔH is negative and its ΔS is positive. The enthalpy of the reaction is negative, since the heat is on the product side of the balanced chemical equation for the combustion of propane, C3H8(g) + 5O2(g) 3CO2(g) + 4H2O(l)+ heat. In addition, the entropy of the reaction is positive, which means it increases in disorder, because the number of gaseous particles on the product side is greater than the number of gaseous particles on the reactant side. Therefore, a process is spontaneous if its enthalpy is negative and its entropy is positive, which in this case proves that the combustion of propane is spontaneous since it satisfies both of these requirements.

Latent heat of vaporization The heat that is absorbed when one gram of liquid is transformed into vapor at the boiling point under one atmosphere of pressure and the result is expressed in BTUs per pound or calories per gram.

In order to get back to your roots, some individuals insist one must get back into touch with nature. Naturally it is the reasoning of man to get back to the basics, the change for growth and opportunity are his pitfall. It is intreging how “man’s best friend” navigates through his environment, seemingly without pitfall. In Jack London’s “ To Build a Fire”, London investigates the dog’s relationship with nature. Within the story, nature is viewed as an opposing force of opposition, hence the constant repetition of the below freezing temperature. In order to progress in his environment, the dog must understand nature and then use his understanding to better the chances of his self preservation.

The purpose of this experiment was to allow for the presence of specific cations within a given solution. By following the procedures, basic solubility rules were better understood. In addition, qualitative analysis was used in tandem with identifying a formed precipitate along with identifying certain metal species by use of a flame test. Careful application of the given procedures allowed for an experiment that did not call for repetition. However, a beaker was shattered during experimentation due to room temperature water being poured into a heated beaker.

This advancement in technology has been able to benefit a large number of peoples and still this is on its way to success. Though this technological advancements have made the working of human life much simpler but at the same time the major issue of ‘fire’ also exists. As more and more of peoples are shifting to the electronic and self operational equipments in their daily routine of life, fire catching risk is there in the same area. The use of devices and material which are highly flammable also give rise to the fire.

Jack London grasped the idea of naturalism when he wrote “To Build a Fire” and he used naturalism to illustrate the brutal unrelenting beast that is nature. London also uses naturalism to stress nature’s dangerous and unpredictable qualities. Basically London is saying that we must be accountable for our decisions and cannot depend on anything but our own will to live and survive. " To Build a Fire" is a short story that incorporates the idea of naturalism and how, if we are not deliberate, nature will win the duel and we will perish. There is no doubt when beginning to read this story that the readers notice the main character is in a dangerous situation with the weather.

Baking Soda - This common ingredient, when heated produces Carbon Dioxide gas. Since the fire would be getting carbon dioxide, the amount of oxygen the fire would be receiving would be limited resulting in the fire being stopped as oxygen is one thing that is required for combustion.

I have picked ‘To Build a Fire’ by Jack London. I’ve chosen this short story cause the title looked promising.

The purpose of this experiment was to use qualitative analysis to identify unknown cations in a solution. The unknown sample #2 was given. In Part A, cations that could possibly be Lead or Silver were separated. The presence of Silver was confirmed. In part B, cations that could possibly be Calcium or Barium were separated.

Purpose To understand and observe the substances that can be identified by the flame color. To observe the colors produced by metallic ions when vaporized in a flame and to be able to identify unknown metallic ions by doing the flame test. Answers to Questions To identify the unknowns, the student could have looked at the flame using a direct vision spectroscope and then compare and observe the lines. Also, if the student had not cleaned the wire properly, then that would interfere with the color of the flame.

Fireworks don’t just look stunning they are also quite educational! The chemistry that goes into building fireworks is complex and interesting. It can even be a fun way to teach children about the basics of chemistry with some fun experiments.

In the story ‘’ To Build A FIRE’’ a new comer beside he is going to travel alone in 75 below zero weather .During his journey he learned a lot of information about the trail he was on. A old man had told him to never travel alone on the trail. Plus the man went on the trail with no food, water, shelter, or any weapons. He walking on the trail and then he fall into lake and he was able to get out of the lake. But it wasn’t good. His feet were frozen and if he didn’t start a fire he would die. The first time he made it some snow fell on it. Then he realized he couldn’t surive so he gave up.
