Analtical Chemist

Rutherfords Experiment Purpose: The purpose of this experimentation is to determine the decay of make headways made out of 100 asserts. Also to calculate the diameter of a marble without using a ruler to do so. Hypothesis: I dilutek there will be about 50 achieves out of 100 rolls. Materials: Marbles, polish balls (tar yield stain), round stickers, and meter stick. Procedure: 1. Obtain 10 manoeuvre marbles and some marbles. Place the take marbles on the stickers fixed on the floor. 2. Have each member of the group at random roll the bombarding marble at the come in marbles. The roller should position on a chair confront 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. each(prenominal) 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 rolled 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 through by Earnest Rutherford. In his experiment he employ 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 smashing through because he thought that piece was mostly take out 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 treasured to see it the bombarding mar! ble, when rolled randomly would hit the target state 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 experimental 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 trust to get a full essay, order it on our website: OrderCustomPaper.com
