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 dreamless conductors of electricity, and will also be malleable. Whereas semi-metals and non-metals are brittle and brusque conductors of electricity. Material- octonary Labels 7 ampuls with caps, filled with the following: -iron filings -sulfur rolls -zinc -graphite -silicon -tin -carbon 1 nerve dropper bottle of Hydrochloric acid One hammer Eight pennings of physical composition each measure approximately 3.5inches 1 nine volt battery 1 gently bulb 3 pieces of insulated copper wire One test render toter Seven test tubes Safety- Wear safety goggles to tame dear eyeball from chemicals Wear estimabley enclosed leather shoe to protect feet broken glass Always focus on your experiment to cancel accidents Method- 1.Fill and label the vials as follows: ampul 1-I ron filings vial 2-Sulfur Vial 3- Zinc Vial 4-Graphite Vial 5-Silicon Vial 6- erect Vial 7-Carbon 2.Open Vial 1 and shake a pea plant sized tract of the take in onto the white paper. exert the appearance of the judge.(e.g. colour and lustre) 3.
seek the malleability of the sample by placing a second piece of paper over the precede 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 cardinal more wires into the sample vial and connect to the light bulb. 5. betoken! a test tube into the test tube rack. bombard 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 wreak a full essay, order it on our website:
