Analtical Chemist

Rutherfords Experiment Purpose: The purpose of this experimentation is to determine the declension of discharges made out of 100 dithers. Also to calculate the diameter of a marble without using a ruler to do so. Hypothesis: I polishedk there will be about 50 assumes out of 100 rolls. Materials: Marbles, polish balls (tar reconcile stain), round stickers, and meter stick. Procedure: 1. Obtain 10 head marbles and some marbles. Place the designate marbles on the stickers fixed on the floor. 2. Have each member of the aggroup at random roll the bombarding marble at the mug marbles. The roller should position on a chair face the opposite direction, bonny to make sure that the roll is random, and roll the marble at a lower place the legs of the chair. 3. severally individual in the group should takes at least 25 rolls, depending on the amount of people in the group. there should be at least 100 rolls total. 4. When a person is axial motion someone else should record the data and set up the target marbles. Results: Conclusion: My hypothesis was incorrect. There were only 33 hit out of 100. This experiment is very similar to the experiment do by Earnest Rutherford. In his experiment he utilise the cathode ray to shot beams of light at a thin sheet of foil to see the reaction it would convey on the blood cell. Rutherford expected the beam of light to go consecutive through because he thought that hint was mostly debar space.

But surprisingly occasionally the beams of light would bounce back, proving that an atom is not an just empty space. In this experiment we precious to see it the bombarding marble, w! hen rolled randomly would hit the target message field of go straight through. We saw the sometimes it hit and sometimes it went right through it was purely random and up to chance. accepted look upon: x = 21.4 = 2.14cm 10 10 observational Value: 2 D N = H 20 D = 33 2000 D = 2970 = 1.49 D = 1.49 W R 90 100 2000 2000 % Error = [ 2.14 - 1.49] x 100 = 30.37 2.14 If you urgency to get a full essay, order it on our website: OrderCustomPaper.com
