The objective of the experiment was to try to figure out what the mystery powder was. I used a bunsen burner, four different types of liquids. We were given eight powders and one of these powders were our mystery powder. And each powder reacted different to the fire and the liquid. We had to go back into our notes and see what matched to what. Materials I used. Were a petri dish, scapula, liquids, burner, C-clamp, tongs, gas to start the flame, eight different types of powders, and the most importa martial was our goggles for safety. The petri dish was used to put the powder in for testing. The scapula was used for scooping up the powders. The liquids were used to see how the powders reacted. The burner was used to see what happen to the
In the short story “Powder,” Tobias Wolff uses indirect characterization to help us understand how the father acts and behaves. First, Tobias Wolff expertly uses indirect characterization by saying “He’d had to fight for the privilege of my company” (Para 1). This allows the reader to infer that the father is reckless or careless and is not trustworthy as he must fight for the company of his son on the ski trip. Secondly, Tobias Wolff uses indirect characterization to show that the father is also caring and wants to take his son skiing as we see in the text “He wouldn’t give up. He promised hand on heart to take good care of me and have me home for dinner on Christmas Eve” (Para 2).
Name: Institution: Course: Instructor: Date of Submission: Absolute zero Abstract The purpose of this laboratory was to apply the ideal gas law and temperature and pressure measurements to extrapolate absolute zero value on a Celsius scale. This was done by recording Pressure and temperature measurement values for different n values.
For this composition, Nell formulated an opaque ash-glaze, which during the firing sequence bonded perfectly with the clay-body of the model. The clay body and the ash-glaze are, during the firing process, transmuted into what a potter would term, a good
The powder that used in the experiment was Sasol Ceralox SPA-0. Alumina powder. The information of the powder is shown in Appendix A. The powder was sprayed into granules. The experiment used die pressing molding to press the alumina powder, with a 2000lb load apply to the top of punch.
The color of the flame help in determining the compound. Reasoning: The Flames test lab shows how different compounds react to heat and energy. After testing all compounds we were able to find out the unknown compounds.
The dH20 allowed for the metal chloride series to stick to the wood, and so that the wood would not burn as easily when placed in the flame. If the wood was not in dH20 it would cause the flame to instead be the color burning wood. In order to get a flame, a Bunsen burner was used, personally I would have used my mixtape instead . The flame needed to be hot, blue, so that the colors emitted by the compounds could be seen easier.
7. Talc Talc is a mineral produced by the mining of talc rocks. It is a toxic ingredient found in baby powders, eye shadows, blush, and deodorant. Talc is used as an absorbent and anti-caking agent.
The objective of the lab Mixed Substances, is to see how properties of individual substances compare with properties of mixed substances. This means comparing one item to a pair of items. The cornstarch is a white, fluffy substance with no smell to it. Also the cornstarch is lightweight and soft to tough. The second substance is water.
The reason why Alexis will be using different substances is to see which chemicals can blow up a balloon faster. The liquids Alexis will be using lemon juice, water, vinegar and baking soda ( mixed together).
Fig shows 3.13 powder diffarction pattern (it shows diffraction lines and holes for incident and transmitted beam) If a powdered specimen is used,instead of a single crystal,then there is no need to rotate the specimen,because there will always besome crystal at an orientation for which diffraction is legitimate. Here a monochromatic X ray beam is incident on a powdered or polycrystalline sample. This method is use ful for samples that are difficult to obtain in single crystal form.
I came to this conclusion the mystery powder lab data table. We found the brands by the blue guide for the powder lab. I think it’s Ms.Tavaglione because properties that the evidence has, her foot powder has. The heat test was was the most important because it can determine what the powder would smell, sound, and look during the heat test. C and D were the only ones that were chemical reactions because they were showing sign of chemicals.
How to Ski Powder in Perfect Posture Right posture and position are needed in ski powder. If you are in right posture and position, you will avoid injury and a bad accident. How to ski powder in the right position will be discussed here. You will get the tips of positional and posture. Starts with Your Hand You need to make a position as if you are reading a big newspaper.
1.) Gather all the instruments required. Gather all the foot powder products and tools like the microscope to help determine fungal infection that causes athlete 's foot or statistic tools to keep record of the effects of the foot powder brands in an athlete 's foot infected test subject. 2.) Make the foot powder.
The experiment process was for the students to inquire about the reaction of the chemicals when mixing them. The materials were, a jar, a spoon, baking soda, dish soap and vinegar. The teacher wanted to demonstrate the chemical change to the whole class. So the students observed the materials first, then the teacher assisted the students to combine the materials. While the chemicals were reacting, the teacher was asking open-ended questions.
A copper vat was used to boil the water over the furnace then was transferred to the mash vat. The mash vat was where they mixed the
