ACTIVITY Place in a beaker aqueous solution of zinc sulfate (ZnSO ), dip a piece of copper wire sanded with steel wool. Observe and record the changes. Stay tuned to aspects of materials. In another beaker, place solution of copper sulfate (CuSO ) and dip a nail or a piece of galvanized galvanized trough, but rather sand objects with steel wool. Observe and record the changes. This means the color change in the solution and the metal surface? Why there was a slight warming in one of the beakers? You mounted two separate systems: one formed by metal (solid phase) copper dipped in the aqueous solution of zinc (liquid phase) and the other by zinc metal (solid phase) immersed in aqueous solution (liquid phase) copper sulfate. Where did the color "red" that appears on the surface of the zinc plate? Why has "disappeared" blue color of the aqueous solution of copper sulfate? Does this have something to experiment with crowned tooth? However, you failed to prove or measure if an electric current actually originated in this experiment, because the electrons transferred were not availed to light a bulb or put in place any device as a watch, a cell phone, a calculator, a laptop computer, a flashlight, a car. One can observe changes in the external appearance in the solution in the beaker and the metal objects. What happens internally at the atomic level? Electric Organ Artificial

AKTIVNOST Mjesto u posudu vodenoj otopini cinkovog sulfata (ZnSO ), umočite komad bakrene žice brusiti s čeličnom vunom. Promatrajte i bilježe promjene. Pratite aspekte materijala. U drugom pehar, mjesto otopine bakar sulfat (CuSO ) i DIP-čavao ili komad pocinčanog pocinčanog korito, već prije pješčanim objekte s čeličnom vunom. Promatrajte i bilježe promjene. To znači promjenu boje u otopini i metalnu površinu? Zašto je blago zagrijavanje u jednoj od čaše? Da montiran dva odvojena sustava: formira se od metala (čvrsta faza) bakra umočen u vodenoj otopini cinka (tekuća faza), a drugi cink metala (čvrsta faza) uronjen u vodenoj otopini (tekuća faza) bakar sulfat. Gdje je boje "crvenih" koji se nalazi na površini od cinka ploče? Zašto je "nestalo" plavu boju vodene otopine bakar sulfat? Da li to ima nešto eksperimentirati s okrunjena zub? No, što nije uspjelo dokazati ili izmjeriti, ako struja zapravo nastao u ovom pokusu, budući da elektroni nisu bili preneseni iskoristio kako bi upaliti žarulju ili staviti na mjesto bilo koji uređaj kao sat, mobitel, kalkulator, prijenosno računalo, svjetiljku, auto. One mogu promatrati promjene u vanjskom izgledu u otopini u posudu i metalnih predmeta. Što se događa interno na atomskoj razini? Električni orgulje Umjetna
