Into each of these test tubes‚ measure out the amounts of solid shown in the second column below (amount per 5 mL). Note: The third column (amount per 100 g of H2O) is proportional to your measured quantity‚ and is the amount you will enter for your graph in Step 7 below. Test tube number Amount

broken. Transfer the mixture to a centrifuge tube to separate the sample into layers‚ to help remove the water. Once the sample is finished spinning extract the organic layer and place in a test tube. TLC: To determine which mixture acetone and hexane is the best developing solvent the first step is to make mixtures of these solvents in test tubes. In the first test tube mix one part acetone (.5 mL) and three parts hexane (1.5 mL)‚ In the second test tube mix two parts acetone (1 mL) and two parts

for this reason that airway and ventilation skills are a vital part of paramedic education and training (Sanders‚ 2007). Endotracheal (ET) intubation is a procedure by which a tube is inserted through the mouth down into the trachea where the patient is often unconscious at the time of the procedure. The endotracheal tube serves as an open passage through the upper airway and is considered to be the “gold standard” in the pre-hospital care setting for complete airway control.

Detergent Hydrogen Peroxide Now that all this apparatus has been obtained‚ it is possible to start the experiment. Eight test tubes will be required because the experiment is being done twice in each water bath. Use a marker pen to mark the specific temperature on the test tubes so as to make sure that there are no possible errors. Now place these test tubes in a test tube rack. Take the cork borer no. 4‚ and take a cylinder of potato using the cork borer. Do this until you have eight cylinders.
