Flame Essays

the color of the flame. The color depended only on the metal component of the compound. The non-metal element that was in the compound did not mater. Compounds with Lithium (Li) were always red, compounds with Sodium (Na) were always yellow, compounds with Calcium (Ca) were always orange, Compounds with potassium (K) were always lilac, and compounds with Copper (Cu) were green. Going down the group there would be higher energy, which is shown through the visible color of the flame produced. It is

with potassium chloride. For example, in “Part A” When the salt was put in the flame it made the flame turn violet. This supports the conclusion that the salt is potassium chloride because potassium chloride also makes a violet flame when burned. The flame test was the most conclusive test because all 8 of the possible salts that were given have very significant flame color. None of the other salts have a violet color flame when burned which goes to prove that the salt is potassium chloride. Another

Flame Tests of the Elements Lab 1. According to your observations, which metal ion is present in your unknown samples? Explain your rationale. According to the observations recorded, the metal ion Cesium is present in the “unknown samples”. Unknown sample number five produced a violet color when placed in the flame. Unknown sample number four produced an orange color when placed in the flame. Unknown sample number one produced a violet color when placed in the flame. This evidence supports the claim

The purpose of the experiment, “Flame Test Lab”, is for one to determine if an element can be identified by the light they give off when inserted in the flame of a Bunsen Burner. The process of the experiment required extreme precaution, since Bunsen Burners were a key material. Students were given six elements to place within the flame of the Bunsen Burner. Lithium, calcium, potassium, copper, strontium, and sodium were all of the elements used during the process of the experiment. Before the experiment

the Flame Test Lab, the purpose was to identify the cation in an unknown substance based on its characteristic color in a flame. Each color is represented by the amount of photons being released by the compound’s electrons. The first compound tested was Potassium Chloride. Potassium Chloride has a slightly pink and purple color due to the salt which produces it. The next substance examined was Sodium Chloride which appeared to be orange because sodium is placed within a blue flame. The flame raises

The celebration of a Wiccaning was afoot, as the feast lighted by a single candle 's flame the house began to glimmer tinted red. In a twinkling of an eye the room had gone quiet, there was nothing to hear but the indistinct reverberation of a riot. The riot was led by the leader of the priests, the madmen who get to define the meaning of

to see if the flames of a fire changes colors when chemicals are added to it. Since different types of atoms have different gaps between their energy levels, they make light of different colors when their electrons lose energy. The chemicals that combine to make these different colors are metal compounds that can burn. In our experiment, the flames did produce different colors. The sodium chloride produced an orange colored flame, the boric acid produced a yellow-green colored flame, the strontium

In the lab, “Properties of Hydrates,” the purpose was to compare the properties of several well observable hydrates and to determine if dehydration is a reversible or irreversible change. The lab consisted of attaining a pea-size sample of each compound, burning it over a bunsen burner, and comparing the starting mass and the mass lost after the combustion. These results are important to be able to identify a variety of different chemicals that contain water molecules as part of their crystalline

the same processes happened as burn 1, but the wax solidified on the sides of the candle. Furthermore, the flame waivered due to air movements around the candle. The candle was 6.3 cm tall and 8.401 g; the burn rate was 2.75 mm/min and 0.066g/min, which shows that the height and the mass decreased slightly more than the other samples. Last but not least, in the burn with the beaker, the flame disappeared in 11.2 seconds due to the lack of oxygen for combustion. In addition, there was excess water

As the passage continues, “The heart of the flame leapt nimbly.” Golding again personifies the flame as growing, the one again is able to form a clear image of the fire, effectively adding to the atmosphere of wonder, felt by the reader as the passage progresses. Again the reader notes the effectiveness of Golding’s use

crucible. Three boiling chips were added in the crucible once it was wiped out with a paper towel. The crucible was then placed on a clay triangle two finger widths above the Fischer burner. After 10 minutes of the crucible being directly under the flame, the it was clean and students allowed time for it to cool down. Next, the students from then on used tongs to transport the crucible from weighing it and back to the clay triangle. Now, they are ready to start the lab. The empty crucible is weighed

elements copper, cobalt, barium, sodium, lithium, and strontium were burned to see the colors which they produce. Each flame was a distinct color and burned at different speeds, meaning that my partners and I had to repeat the step of burning the element several times in order to get precise results. The experiment was mainly conducted to see the light spectra that the colored flames cast, and to become acquainted with using spectroscopes. One of the elements used in this lab, lithium, is used to make

candles of the same size and brand. 2. One candle will be red and the other will be white. 3. Next you will put them into two heat/fire safe containers. 4. Then start to burn them. 5. Keep them both at the same temperature. 6. They will be burnt under a flame and they will be

Incredible Full Sleeve Tattoo Ideas: Which One is Right For You? If you are serious about tattoos you’ll probably consider getting a sleeve tattoo at some stage. A sleeve tattoo refers to a number of similar tattoos inked closely together that covers the area almost completely, in a close-knit pattern. Today we are talking about full sleeve tattoos but there are other kinds of sleeves as well. A half sleeve stretches from the wrist to the elbow while a full sleeve is from the wrist to the shoulder

To purify metal you have to melt the ore in a crucible, or a container that can resist great heat. A crucible, such as a steel container, clay, and some ceramics can withstand great heat. Crucifixion, the SAT’s and Mr.Maloney's class are all examples of a crucible. Where everyone who enters or gets chosen is severely tested. The Romans placed gladiators in a crucible, a container called a coliseum to fight to the death. I was very contentious with my parents as they wouldn’t let me go to a friends

Today, there is at times nearly as much concern about the materials with which we store and prepare food as there is about food itself. Cast iron cookware is an attractive alternative to the chemical-laden stainless steel and aluminum cookware that dominates the majority of American kitchens. In a way, the use of cast iron cookware is nostalgic because in many previous centuries iron was the metal of choice for our ancestors' pots and utensils.

element. One of these methods is the study of colors emitted by the element when exposed to an energy source. Flame tests are a fast and reliable method of determining the identity of unknown metal ions. The Flame Test was designed to test different metal ions to observe the colors that each chemical makes. The Flame Test was also used to identify unknown metallic ions based on the color of the flames produced. In this lab, Petri dishes each containing a different metal ion were doused in ethanol and lighted

With flame holders you can locate the ideal one that will compliment or even outwardly make the light seem to cost more, or even show up originator. On the off chance that you have a major flame holder, or even need an enhancement or your divider then a period divider sconces holder would do the trap for you. There are a wide range of sorts of light holders available today. The trap is to locate the ideal light holder for your inside embellishment, or even around a specific kind of flame. A votive

known cations, potassium iodide, barium nitrate, and copper (ll) sulphate. First thing that needed to be done, was to determine exactly which cation(s) consisted in the substance using quantitative analysis. In order to come to that conclusion, the flame test was conducted. Before the lab has commenced, three laboratory bottles containing the three different cations, a laboratory bottle containing the unknown solution, a bunsen burner, tongs, a flint, paper clips, and goggles were obtained. Before
