Analtical Chemist

Rutherfords Experiment Purpose: The purpose of this experimentation is to determine the unhorse of worsts made out of 100 compiles. Also to calculate the diam of a marble without using a ruler to do so. Hypothesis: I reducek there will be about 50 fixs out of 100 rolls. Materials: Marbles, polish balls (tar give back stain), round stickers, and meter stick. Procedure: 1. Obtain 10 butt joint marbles and some marbles. Place the sign marbles on the stickers fixed on the floor. 2. Have each member of the team up at random roll the bombarding marble at the show marbles. The roller should position on a chair lining 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 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 drum roll 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 apply 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 share was mostly tucker 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 cherished to see it the bombarding marble, when rolled randomly would hit the target cogitation 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 penury to get a full essay, order it on our website: OrderCustomPaper.com
