Analtical Chemist

Rutherfords Experiment Purpose: The purpose of this experimentation is to determine the riposte of marks made out of 100 drops. Also to calculate the diam of a marble without using a ruler to do so. Hypothesis: I sharpk there will be about 50 expunges out of 100 rolls. Materials: Marbles, polish balls (tar plunge stain), round stickers, and meter stick. Procedure: 1. Obtain 10 drive marbles and some marbles. Place the pose marbles on the stickers fixed on the floor. 2. Have each member of the group at random roll the bombarding marble at the buttocks marbles. The roller should position on a chair go about 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. individually 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 bankroll 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 with(p) 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 clean through because he thought that blood cell was mostly expatriate space.

But surprisingly occasionally the beams of light would bounce back, proving that an atom is not an just empty space. In this experiment w e cute to see it the bombarding marble, wh! en rolled randomly would hit the target opened 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 postulate to get a full essay, order it on our website: OrderCustomPaper.com
