Argumentation Documentation In this lab‚ the goal was to create a ‘rocket’ out of a pipette and to determine the right ratio of Hydrogen to Oxygen to Water in order to generate the maximum possible flight distance. My partner and I arrived at our ratio of 1.5:3:1.5 (H2:O2: H2O) because of its consistency‚ high distance‚ and a bit of gut feeling. We had a few ratios that worked pretty well including 2:3:1 and 2.5:2:1.5 (see graph/chart)‚ but we chose ours because it felt like a good decision‚ and

Introduction. Friction was studied in this lab. The experiments were conducted using a clipboard glued to various surfaces with diffirentiating frictional properties. In order for us to test the varying Static friction or Kinetic friction we used a Newton force gauge‚ some wooden blocks‚ and a metal weight. The actual experiment consisted of two parts. The first part measured the net force‚ or more specific the net force required to overcome the kinetic friction coefficient‚ to move the block across

Miguel Paulo D. Valdez BS Chem-3 EXPERIMENT 14- Heat Effects and Calorimetry Objective/ Introduction: Heat is a form of energy‚ sometimes called thermal energy‚ which can pass spontaneously from an object at a high temperature to an object at a lower temperature. If the two objects are in contact‚ they will‚ given sufficient time‚ both reach the same temperature. Heat always travels from hot to cold objects and two objects will reach an equilibrium temperature. Heat flow is commonly measured

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive
