Recommended: Flame test observation
Chemical compounds that are available to determine are CaCO3, CaCl2, Ca(NO3)2, mgCl2, MgSO4, KCl, HCl, HC2H3O2, KNO3, K2SO4, NaC2H3O2, Na2CO3, NaCl, Na2SO4, HNO3, H2SO4, HNO3, H2SO4, NH4Cl, (NH4)2SO4, K2CO3, 0.1 M AgNO3, 0.2 M BaCl, Mg(s), NaOH, and KOH. To start this experiment, start with the flame test by gathering a Bunsen burner and a Nichrome wire. Connect the Bunsen burner with a rubber tube to a laboratory gas. To prepare solutions for the flame test, weigh out 0.205 gram of Unknown Compound using an analytical balance and mixed it into a 140 mL beaker filled with 20 mL ionized water. Ensure that solid is completely dissolved using a stirring rod.
Some compounds have very distinctive colors when burned, such as Potassium, which is a white/purple, and sodium, which is a deep red hue. The first step for a flame test is to gather the needed materials. These include beakers, distilled water, the unknown substance, a Bunsen burner, matches, a nichrome wire, tubing to connect the gas line to the Bunsen burner, goggles, and known compounds to compare with. The first step is to make aqueous solutions of all the substances to be tested. This is done by adding .5
In the novel Tangerine, the protagonist, Paul Fisher, and his mother move to Tangerine, Florida to meet up with his father and older brother Erik at their new home. The family has moved due to Mr. Fisher’s work and expected their new home in Lake Windsor Downs to be perfect. However, the problems beneath the surface become apparent the longer they live there. Koi fish in the lake go missing, a sinkhole occurs at the local school, and termites eat away at neighborhood homes. Tangerine presents a perfect guise that conceals its ugly imperfections.
When the students placed the wire containing the sample in the flame it burned a orange/ red color. when this result was compared with the previous flame tests it could have resulted from either CaCl2 or NaCl. Both of these compounds produced an orange flame. After the flame test was conducted, the students performed a litmus test to identify whether the unknown was neutral or a base. When exposed to the red and blue litmus paper, no reaction occurred.
Sherpa fire in Santa Barbara grows to 4,000 acres overnight, putting about 140 homes at risk and closing down major freeways according to federal officials. The fire started on Wednesday afternoon on coastal hills north of Santa Barbara. It had moved through overgrown hillsides and canyons that have not been burned in over 60 years because of the hot and dry weather and notorious “sundowner” winds. Sundowners, similar to Santa Ana winds, fuel many of the fires in the Santa Barbara County.
In the eighth grade, my friends and I joined a program called History Day, completely on a whim. We had no experience and we barely knew what the program was, but we were very excited to try something new. When we got started on our project, we decided to do a performance on the Triangle Shirtwaist Factory Fire of 1911. Out of the five of us, not one person had done a historical performance before, and so with no experience we began our research. As we learned everything there was to learn about this event, we became more and more passionate about the topic.
The diction of fire in Fahrenheit is pretty confusing because it's not just one word. There’s multiple words to describe fire that may even seem shocking because of the ways it’s presented. In this analysis, you’ll find that Ray Bradbury is taking fire to a whole other level. He’s not just describing the physical appearance, but also the literal sense of fire. By the end, Bradbury’s message will be clear.
The book “Forged by Fire” by Sharon M. Draper is a book with many themes and lessons we all can learn. One of the themes that this essay will talk about will be about loyalty. For one thing, loyalty is a strong feeling because it’s something that comes from inside of a person to have faith in someone . We are all loyal to someone, someone who’s special in our lives and plays a major role in our lives that drags us to support them no matter what. In this book, Gerald gets abused by his drunk father.
The Fire Stick, utilised by Indigenous Australians has been an essential tool in the practice of traditional land management across Australia since their arrival 50,000+ thousand years ago. Fire Stick Farming (as it is now known) shaped the Australian landscape in ways that benefited both land and Aboriginal people. A practice that increases biodiversity of plant species, offered an abundance of food, both for Aboriginal people and wildlife such as the Kangaroo and Emu, and, in turn, increased populations of these species, which were also a desired food source. Additionally, the practice of burning both small and large areas of land ensured the prevention of larger uncontrollable fires which can devastate landscapes, as evidenced by the common
In this lab, students observed the reactivity with water of three Group I elements: Li, Na and K. These elements all had the same valence electron configuration. Because of this, the students predicted that they all will have similar reactions. When the lithium was placed in water it started bubbling and moving quickly across the surface while it dissolved. Sodium initially sank to the bottom and the bubbled back to the top before skirting across the top of the water before catching on fire and giving off sparks.
Title: THE BALLOON INFLATION REACTION Introduction: Chemistry is one thing that makes us understand and gives us reasons of why certain reactions gives certain results. In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases.
The emission spectrum of a chemical element is the spectrum of frequencies of electromagnetic radiation due to an atom or molecule making a transition from a high energy state to a low energy state. There are a lot of electron transitions for each atom. All transitions have a energy difference. After doing the atomic line emission lab my results came out in many different ways.
To Build a Fire During the story “To Build a Fire” the theme that is developed is that sometimes you have to trust animals instincts because they might know more about the fire than you do. The setting of the story is on the Yukon Trail and it is seventy five degrees below zero while the man and the dog are on the trail. The reason they are on the trail is because the man is trying to find the camp to get food, water, and shelter. There are two ways the theme is developed. One way that the theme is developed is that the man made a fire to keep him warm, but later the man wanted to continue on the trail to try and find the camp.
The Best Story So Far:”To Build A Fire” The best short story that I’ve read so far in class is “To Build A Fire” by Jack London. The story is about an unnamed man during during a really cold day in Alaska. The man sets off with his dog and a lunch and heads for the cabin on Henderson Creek to meet up with the boys. Well, along the way the man doesn't recognize the significance of some of his observations like the cold and falls into a creek which delays him on his trip.
III Types of fire retardants Numerous chemicals having different structure and physical properties could impart fire resistant characteristics when used alone or in combinations. Combinations of different fire retardants with varying proportions can produce an additive, synergistic or antagonistic effect. The synergy of combining fire retardant chemicals has gained considerable practical importance as they are usually less expensive [13, 20]. Fire retardant chemicals can be either chemically bonded reactive type or the additive type where the retardant is applied as coating to the base material and the retention of retardant is by weak secondary bonding and not covalent bonding unlike the former [13,20].
