Experiment

Plan An Investigation To Examine The Properties of Metals, Non-metals And Semi-metals Aim- To examine the properties of metals, non-metals and semi-metals. Hypothesis- Metals are secure conductors of electricity, and will also be malleable. Whereas semi-metals and non-metals are brittle and unmindful conductors of electricity. Material- eight Labels 7 ampuls with caps, filled with the following: -iron filings -sulfur rolls -zinc -graphite -silicon -tin -carbon 1 midpoint dropper bottle of Hydrochloric acid One hammer Eight pennings of ensnare each measure approximately 3.5inches 1 clubhouse volt battery 1 gently bulb 3 pieces of insulated copper wire One test render toter Seven test tubes Safety- Wear safety goggles to demand dear eyeball from chemicals Wear estimabley enclosed leather office to protect feet broken glass Always focus on your experiment to cancel accidents Method- 1.Fill and label the vials as follows: ampul 1-Iron fi lings phial 2-Sulfur Vial 3- Zinc Vial 4-Graphite Vial 5-Silicon Vial 6- stool Vial 7-Carbon 2.Open Vial 1 and shake a pea plant sized tract of the take in onto the white paper. conform to the appearance of the exemplar.(e.g. colour and lustre) 3.

seek the malleability of the sample by placing a second piece of paper over the exculpate of the sample and crush with the hammer. take aim the top piece of paper and observe the sample. 4.Test the conduction of the sample with the 9V battery by placing the ends of the connected to the 9V battery into the sample vial. Then place dickens more wires into th e sample vial and connect to the light bulb.! 5. regulate a test tube into the test tube rack. stream sample 1 from the paper (step 2) into the test tube. Add 15 drops of hydrochloric acid into the test tube. sojourn at least 3 minutes before sight then recording the observations of the sample reacting with an acid. 6.Repeat steps 2-5 for the stay six vial samples.If you want to bring on a full essay, order it on our website: BestEssayCheap.com
