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
My experiment is elephant toothpaste were foam shoots out of a container or glass. I chose this experiment because I thought it would be fun to see foam shoot out of a bottle. You get to mix curtain substances together to make elephant toothpaste. I thought if I get a small bottle then the most foam should be produced.
First, you place the bunsen burner on the ring stand and tightly place the metal ring and place the clay triangle on it. Before placing the crucible on the ring you must put baking soda in the crucible, and place it on the ring stand. Then with safety precautions light the bunsen burner with the matches provided. In our first experiment we first started with 1.04 grams of NaHCO3 and ended with .60 g Na2CO3. In the second experiment we started with 3.2 g NaHCO3 and had a result of 2.0 grams
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).
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 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).
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.
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.
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.
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.
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
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.
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.
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.
