The iron filings will stick to the magnet. The filings can be removed by unwrapping the plastic from the magnet carefully. Pour the mixture into a beaker containing hot water and mix (this will cause the Styrofoam to
When I cleaned up I made sure I cleaned the surface area thoroughly and washed my hands. Conclusions and Observations: Table 1: Experiment Data | Grams | Percent of Mixture | Iron filings | 1.4g | 31.1 | Sand | 1.3g | 28.9 | Table Salt | 1.0g | 22.2 | Benzoic Acid | .8g | 17.8 | Total | 4.5g | 100 | A. My proposed procedure at the beginning of the experiment was a little different because I would have used the filter paper to get the sand out of the mixture. I did though propose to use the magnet to take out iron. B.
The pencil should be able to sit across the top of the beaker with the bottom of the paper strip just touching the bottom of the beaker. Cut off any excess paper from the top of the strip if it is too long. Do not cut the bottom of the strip with the green line. -Remove the pencil/paper strip from the beaker for now -Carefully add isopropyl alcohol to the beaker until it reaches the paper strip extending into the beaker until it reaches a depth of 1 cm in the beaker -Lay the pencil across the top of the beaker with the paper strip
Swab the rubber top with alcohol and allow to dry. 6. Seat the needle. Remove the cap from the needle or blunt cannula by pulling it straight off. Draw back an amount of air into the syringe that is equal to the specific dose of medication to be withdrawn.
Practice spotting on a piece of filter paper. Use toothpicks to apply a drop of each cation solution in the appropriate columns, Place the paper in the 600 mL beaker, then immediately re-cover it, Without agitating the solvent, allow the solvent front to rise within 1 cm of the top edge before removing the plastic cover. Perform 3 spot tests, and record the results on Data Sheet 1. Once the solvent front is within 1 cm of the top edge of the paper, remove the paper and mark the final position of the solvent front with pencil. Re-cover the beaker, and completely dry the paper.
After 1 minute has passed, put the wax paper and the potato chips into the trash. Try to remove all of the extra bits from the graph paper, too. Do you notice a grease stain on the graph paper? Tape the paper to a well-lit window so that you can see the stain clearly. 6.
Rinse brain. Make sure that the pieces do not wash down the sink-put them in the garbage bag that is to be used for collecting brain waste. 3. Put brain on newspaper on the dissection board. 4.
Hold the test tube top down, to prevent it from coming off and making the test inaccurate. 6. At 200 seconds stop your recordings and you may take the plug out of the test tube. 7. Clean the test tube and put it on the drying rack.
Immediately wash contaminated skin with large amounts of water. * Inhalation: Remove person from exposure. Begin rescue breathing, if breathing has stopped. (http://olinchloralkali.com/Library/MSDS/MSDS0505.pdf) e. Should this chemical be labeled with a corrosive, flammable or flammable label? Yes.
Make a hook on the end of the coil to allow the coil to be suspended from the stirring rod. - Nothing 5.) Hook the coil onto the middle of the stirring rod. Place the stirring rod across the top of the beaker immersing some of the coil in the AgNO3 solution. The copper turned black after a sec.
