In fact, the wax itself is burning as a vapor or gas. Objectives 1. What happens to the candle when you light it? 2. Can you prove that the candle needs oxygen in order to burn?
Experiment Chromatography Of Food Dyes Abstract This experiment is to determine the presence of a mixture in a substance. Chromatography is used to separate substance in a mixture or separating components from a mixture. Using chromatography with a solvent we are able to separate the different mixtures found in a substance. Chromatography can tell if a sample is pure or if it is made up of several different substances. Experiment & Observation I gathered together my items; distilled water, salt, ruler, scissors, stapler pencil, tape, 16 toothpicks, Kool-Aid drink mix strawberry and grape, set of McCormick food coloring red, yellow, green and blue, small bag of M&M candy, plastic beaker 50 mL, petri dish 60mm, well-plate 24, FDC blue dye #1 0.5 mL vial, FDC blue dye #2 0.5 mL vial FDC red dye #3 0.5 mL vial, FDC red dye #40 0.5 mL vial, FDC yellow dye #5 0.5 mL vial, FDC yellow dye #6 0.5 mL vial, unknown 0.5 mL vial, 3 filter paper chrom 14x7 cm.
In the experiment four brands of microwave popcorn will be tested; Orville Redenbacher, Act II, Pop Secret, and the generic store brand (Kroger). Once the experiment is finished, it will be evident which brand had the most popped kernels. Literature Review There are two experiments I found that are similar to this one. There were some differences in the testing methods and some of the brands
(As you can guess, different fuels begin burning at different temperatures.) Heat or ignition sources lift fuel (combustible material) to its activation energy to start the fire. The fire generates heat which sustains the chemical reaction; the blaze continues and spreads. Some firefighting tactics shield the fuel from air (oxygen) to extinguish the blaze. Carbon dioxide fire extinguishers expel a cold fog of CO2 that cuts a fire off from its air supply.
The candle wax burns as a vapor because when the smoke it’s put into the other flame, the flame gets bigger which means it’s feeding off of the smoke. That means wax has to burn as a vapor because it’s the only thing present. 3. The other requirement is oxygen because when the flask was put over the flame, the flame went out when the flask became a vacuum before the water reached the flame. 4.
Then add in the sausage, bay leaf, can chicken broth, and some of the seasonings. What you want to do here is make sure you’re not over seasoning the gumbo. Add just a little then wait to see how much seasonings will come out of the sausage before adding more. Also at this step you add in the shelled boiled eggs so the eggs can soak up the roux and
Purpose/ objectives: 1. To learn if food concentrations affect yeast activity 2. To improve skills in writing a lab report better 3. To practice measuring skills 4. To understand how yeast works Materials: * * 6 identical large test tubes (18 X 150mm) * 1 graduated cylinder (24ml) * Molasses stock solution ( 1:4- molasses: water) Dropper * Yeast suspension (1 gram of dry yeast in 100 mls water) * Aluminum foil * 1 test tube rack * 1 graduated cylinder (small) * 1 beaker * 6 small test tube (10 X 75mm) * Rule marked in millimeters Hypothesis: If you add more molasses to the yeast then the gas would became greater because the yeast cells reproduce so the waste became greater and
Measuring Cylinder (1) f. Beaker (1) Results Table: Name of Compound | Observe atomic admission | Calcium Chloride CaCl2 | The flames turned into an orangey color then gradually turned redish brown with a bit of orange. | Barium Chloride BcCl2 | The flames turned into yellowish color then it became whitish and brownish and eventually turning green. | Magnesium ChlorideMgCl2 | The metal salt bubbled when it hit the flames then its flames turned orange and yellow. And the substance that is left on the spatula turned into a glue like white mask. | Nickel ChlorideNiC12 | The substance was green originally but turned yellow after being exposed to the flames.
* Explain the air plasma cutting procedure. * List the advantage and disadvantages of using a air plasma cutting torch 3.0 INTRODUCTIONS Plasma is an ionized gas that conducts electricity. Plasma is created by adding energy to an electrically neutral gas. In this case, the gas is compressed air and the energy is electricity. The more electrical energy added, the hotter the plasma arc becomes.
Once the balloon is removed, electrons redistribute themselves about sphere A until the excess negative charge is evenly distributed across the surface. In the end, sphere A becomes charged negatively and sphere B becomes charged positively. This induction charging process can be used to charge a pair of pop cans. It is a simple enough experiment to be repeated at home. Two pop cans are mounted on Styrofoam cups using scotch tape.
