First, we gathered seven various solids and placed them into separate wells. After we divided the solids into two separate well holders, we placed 15 drops of Copper Chloride solution to one of the well holders, and recorded the observations. Afterwards, we placed 15 drops of hydrochloric acid to the other well, and again recorded the observations. We also recorded which elements reacted with which liquids. Finally, we washed our hands cleaned our lab station up.
Procedure:
In this lab, we tested 7 different substances to see whether they were metal or nonmetal. We recorded the results of different tests such as conductivity, results when smashed with a hammer (to see if the substance was brittle or malleable), and reactivity with CuCl2 and HCl on our data table.
To test if our substances were conductive we pressed two wires that were connected to a battery onto the surface of the substance and saw whether the light bulb attached lit up.
Next, we hammered into the substances. When the substance dented or flattened, we determined it was malleable. On the other hand, when the substance shattered, we determined it was brittle.
Lastly, in the reactivity column, we recorded the substances' reactions when we placed 15-20 drops of CuCl2 into each well. We did the same thing with HCl.
From this lab, we have seen the many physical and chemical characteristics that each object has. Objects B, C, D, E, and G are brittle. But A and F are malleable. Using this information and our knowledge we have realized what type of metals these are: objects B, C, and E are non metals, D and G are metalloids (they include characteristics that are both metal and non-metal), and A and F are metals.
Conductivity = Physical Property
Crushing = Physical
Reacting with CuCl2 = Chemical Property
Reacting with HCl = Chemical Property
2) Physical Properties = A, F, D, E, G
Chemical Properties = C, B
3) E, C, and G can fit into both categories because they have properties of both
4) Metals = A, G
Nonmetals = B, C, D, E, F
Metalloids = B, D, E, G
