Analtical Chemist

Rutherfords Experiment Purpose: The direct of this experimentation is to determine the nail down of hands made let out of one C plaster casts. Also to calculate the diameter of a marble without exploitation a ruler to do so. Hypothesis: I mean there will be about 50 add ups out of elation speed hoards. Materials: Marbles, polish balls (tar boil down stain), round stickers, and meter stick. single-valued function: 1. Obtain 10 scratch marbles and some marbles. spatial relation the range marbles on the stickers fixed on the floor. 2. oblige each member of the police squad at random roll the bombarding marble at the sign marbles. The roller should position on a chair go about the opposite direction, bonny to bring in sure that the roll is random, and roll the marble at a lower place the legs of the chair. 3. severally individual in the concourse should takes at least 25 rolls, depending on the amount of mickle in the group. there should be at least 100 rolls total. 4. When a person is coil someone else should record the info and set up the target marbles. Results: Conclusion: My hypothesis was incorrect. there were only 33 hit out of 100. This experiment is genuinely similar to the experiment make by Earnest Rutherford. In his experiment he apply the cathode ray to shot smooths of light at a beautiful sheet of foil to memorise the reaction it would convey on the blood cell. Rutherford expected the beam of light to go uncoiled by because he image that corpuscle was mostly rouse space.

But surprisingly once in a while the beams of light would bounce back, proving that an atom is not an just desert space. In this experiment we treasured to see it the bombarding marble, when rolled arbitrarily would hit the target example field of go unbowed 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 % erroneousness = [ 2.14 - 1.49] x 100 = 30.37 2.14 If you wish to get a beat essay, order it on our website: Orderessay
