In this lab we will produce acetylene by placing calcium carbide (CaC2) in water. Write the chemical formula for the reaction between calcium carbide and water knowing that the product is acetylene (C2H2). 2. The acetylene in this lab will be collected in a test tube and burned. Write the balanced

find the rate of reaction of the decomposition of hydrogen peroxide. * Control Variable- 1mL of yeast (catalyst) is being used in every trial. The volume of H2O2 is always 4 mL‚ even though the concentration changes and the sizes and type of test tube was the same because it can change the pressure. * Independent Variable- Concentration of H2O2 (M) and the temperature (°C) * Dependent Variable- The rate of reaction of the decomposition of hydrogen peroxide → rate of reaction = ∆ Pressure

Tracheostomy Tube A tracheostomy tube‚ or trach tube‚ allows a person to breath without using his or her nose or mouth. Some trach tubes have a cuff on the end that keeps air from reaching the mouth and nose. A cuffless tracheostomy tube does not have a cuff. Since there is no cuff‚ a person with this kind of trach tube can cough and speak normally. Two people are needed to change a cuffless trach tube. SUPPLIES NEEDED Clean gloves. A new trach tube and an emergency trach tube. One tube should

YAMBAO‚ Monn Juleuse F. mjfyambao@gmail.com E304: Kundt’s Tube: Velocity of Sound in Solid METHODOLOGY Two experiments were done last time due to some circumstances that made the class to lack time and to be late compared to the official class syllabus. The students were able to accomplished the job by equally dividing the time into two. The first experiment was about Kundt’s tube. In this experiment‚ longitudinal sound waves will be produced in a metal rod and an air column. Using the properties

Introduction The 14-French (F) pigtail catheters (PCs) are small-caliber catheters that are percutaneously placed at bedside‚ in comparison with the tradition large-caliber (32-40F) chest tubes (CTs) that are placed by an open cut-down technique 1-3. The PC’s roles and its effectiveness in the management of trauma patients with pneumothorax 3 and hemothorax (HTX)/hemopneumothorax (HPTX) 4 have previously been published. It is controversial and many clinicians still question whether or not blood

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
