Experiment

Plan An Investigation To poll The Properties of Metals, Non-metals And Semi-metals Aim- To examine the properties of metals, non-metals and semi-metals. Hypothesis- Metals are unassailable conductors of electricity, and will also be malleable. Whereas semi-metals and non-metals are brittle and mulct conductors of electricity. Material- Eight Labels 7 ampuls with caps, alter with the following: -iron filings -sulfur rolls -zinc -graphite -silicon -tin -carbon 1 nub dropper bottle of Hydrochloric acid ace hammer Eight pennings of authorship separately measure approximately 3.5inches 1 nine volt battery 1 gently bulb 3 percentages of insulated atomic number 29 wire One test impart necessitateer Seven test metros Safety- interrupt safety goggles to hold dear eyeball from chemicals have on estimabley enclosed leather billet to protect feet broken glass incessantly focus on your experimentation to cancel accidents Method- 1.Fill and label the ampuls as follows: ampul 1-Iron filings phial 2-Sulfur ampoule 3- Zinc ampul 4-Graphite Vial 5-Silicon Vial 6- Tin Vial 7-Carbon 2.Open Vial 1 and shake a pea sized tract of the ready in onto the white paper. value the appearance of the audition.(e.g. colour and lustre) 3.

seek the malleability of the render by placing a second piece of paper over the go on of the sample and crush with the hammer. make up aim the top piece of paper and observe the sample. 4.Test the conductivity 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. situation a test tube into the test tube rack. well out sample 1 from the paper (step 2) into the test tube. Add 15 drops of hydrochloric acid into the test tube. rest at least 3 minutes before cud 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 birth a full essay, methodicalness it on our website: Orderessay
