Monica Perez Experiment 8: Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate

questions: force and motion I problem 1 The figure below is an overhead view of a 12 kg tire that is to be pulled by three ropes. One force (Fl‚ with magnitude 50 N) is indicated. Orient the other two forces F2 and F3 so that the magnitude of the resulting acceleration of the tire is least‚ and find that magnitude if (a) F2 = 30N‚ F3= 20 N; (b) F2= 30 N‚ F3 = 10 N; and (c) F2 = F3 = 30 N. problem 2 A weight-conscious penguin with a mass of 15.0 kg rests on a bathroom scale (see figure below).

Proud Moments in our history Canada has had many proud moments in the past 100 years that makes us who we are now. Vimy Ridge was one of our first proud moments in the 1900s where all four Canadian divisions in World War I fought in one battle together. After the First World War Canada became its own country by the Statute of Westminster stating that we were no longer was about of Great Britain. In the 1920s Canada invented many useful things that we still use today like the telephone‚ radio

Moment of inertia of a flywheel Jonathan Prevett 13/11/14 Uday Ravish Aim: To determine the moment of inertia of a flywheel. Apparatus: Fly wheel and axel‚ weight hanger‚ slotted weights‚ stop watch‚ metre ruler. Definitions: Moment of Inertia- a quantity expressing a body’s tendency to resist angular acceleration Radius of Gyration- the distribution of the components of an object around an axis. Method: The weights were suspended from the axel by the cord‚ then we used a meter ruler to make
