Analtical Chemist

Rutherfords Experiment Purpose: The purpose of this experimentation is to determine the sink of get aheads made out of 100 cast offs. Also to calculate the diameter of a marble without using a ruler to do so. Hypothesis: I shrinkk there will be about 50 realizes out of 100 rolls. Materials: Marbles, polish balls (tar crash stain), round stickers, and meter stick. Procedure: 1. Obtain 10 purpose marbles and some marbles. Place the fall guy marbles on the stickers fixed on the floor. 2. Have each member of the team up at random roll the bombarding marble at the range marbles. The roller should position on a chair cladding 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. for each one 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 roller someone else should reco rd 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 utilize 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 continuous through because he thought that division was mostly wash up space.

But surprisingly occasionally the beams of light would bounce back, proving that an atom is not an just empty space. In this experimen t we precious to see it the bombarding marb! le, when rolled randomly would hit the target font 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 insufficiency to get a full essay, order it on our website: OrderCustomPaper.com
