Explore chemical cells: turn chemical energy into electricity! Learn about electrolytes & electrodes.

Fill in the blank When the parts of a chemical cell are connected, chemical energy is changed into electrical energy. wires electrolyte electrodes Use lab book if needed. When electrodes are placed in the electrolyte, a chemical reaction takes place. This causes electrons to be attracted to one electrode, but not the other. This difference in the amount of electrons on each electrode is called potential difference Potential difference causes current to flow; another name for potential difference is _. electrode amps voltage electricity Fill in the energy chains for these devices: Chemical cell (Battery): chemicalenergy --> electricalenergySolar cell: radiantenergy --> electricalenergyPlants growing: radiantenergy (sun) --> chemicalenergy (plants)Flashlight: chemical energy --> electrical energy --> radiant energy What is the importance of anelectrolytein a chemical cell? electrolytes act as a conductor for electrons to flow an electrolyte provides the electrons for the current In this lab, which of the following did we not test as an electrode? zinc copper carbon sodium According to this data, which combination of electrodes gave the highest voltage? magnesium and carbon magnesium and zinc copper and zinc zinc and carbon According to class data, which combination of electrons gave the lowest voltage? copper and zinc magnesium and zinc copper and magnesium zinc and zinc In this lab, what was the electrolyte? carbon magnesium lemon juice Gatorade
