beakers contain the same compound. You may try some of the followings: * Dissolving in water * Dissolving in different chemical solution * Heating both substance to see if they come out with different results * Doing the flame test for both solution to see if they can come out with different results * etc * b. Would it be easier to prove that the

In Alice Walker's short story, "Everyday Use," Wangero could have thought: "Ashes to Ashes. Dust to Dust." Once the house burned, it, and its history is dead--lost in the flames-- the joy in a new start, a new life, a new name must have made Wangero want to "dance around the ashes (66)" of the house. Dee did in fact change her name to "Wangero Leewanika Kemanjo." When her mother asked her why she didn't use her name anymore Wangero answered: "She's dead, I couldn't bear it any longer being

candle and stayed in the flame, while Dillard witnesses the moth’s death. As the fire burnt its wings the light and the flame from the candle increase until they are completely demolished, causing the flame to subside. At this point the moth is still alive, and continued to move its legs until they finally become still, and the moth is fully dead. Her antennae are also consumed by the fire as well as her legs and head. With only the skeleton of the moth left, it fuels the flame. Dillard reads for another

When they walked through the doors of the haunted house in the graveyard, it had an instantly spooky aroma. The door itself was wooden and starting to rot away and fall from its hinges, although that kind of describes the whole house, falling apart. To the right there was a small staircase with ten or eleven steps leading upstairs and a doorway below them leading downstairs. There was old furniture scattered across the old house but it was all ripped up or broken. To the left of the room was a locked

Throughout this lab, many different experiments were tested on the unknown white compound. The first test ran was the Solubility Test, which was started by measuring 0.03g of the unknown substance. Next, measure out 60ml of distilled H2O and mix with 0.03g of unknown. Use a stirring rod to the substances were mixed together, and observations were made to see if the unknown dissolves. The use of a ionic solubility chart was helpful when running this test. The next test that was conducted in this

describe the burning candle. Blow out the flame and immediately place a lighted match in the “smoke”

Furnace Smells And Sounds To Watch Out For A furnace that is working properly should not bring any attention to it. There will be a hum while the unit is running that you may faintly hear throughout your home, but it is nothing to be concerned about. However, there are some odd sounds and smells that should make you concerned about your furnace. Furnace Sounds Your furnace can make some sounds that you should be concerned about. Rattling Rattling is a sound that is telling you that something

In the Flame Test Lab we took different ions of salt and put them over a bunsen burner to determine the wavelength of the light. The wavelengths of light visible are in the group visible light: red, orange, yellow, green, blue, indigo, and violet. The colors in which we view an object are reflected off the object, the other colors are absorbed. Each element has a specific color that is given off; it is like a fingerprint. We recorded this data and compared it between the different salt ions, After

core, it produced the most amount of heat, bubbles, and the biggest flame during the glowing splint test. The manganese dioxide and the liver core were also very reactive and they both produced a flame during the glowing splint test. Next, the potato core produced a slight reaction, but it was not as extreme as the other substances. Finally, just the hydrogen peroxide and the boiled liver core had no reaction and did not produce a flame during the glowing splint test. Sources of error A few sources

variable was the size of the beaker (or the volume of the beaker). Dependent Variable: The dependent variable was the duration of the candle flame (or the time it took for the flame to be smothered). Controlled Variable: The controlled variable was the burning candle flame. Hypothesis If the size of the beaker was increased, then the duration time of the flame would increase as well. (not yet) Since there would be more volume in the beaker, the amount of air (and subsequently the amount of oxygen)
