Chemical Cells and Electrical Energy

Unlock the secrets of chemical cells and electrical energy! Learn how they generate power.

Fill in the blank When the parts of a chemical cell are connected, chemicalenergy is changed into electricalenergy. wires electrolyte electrodes Use lab book if needed. When electrodes are placed in the electrolyte, a chemicalreactiontakes place. This causes electronsto be attracted to one electrode, but not the other. This difference in the amount of electrons on each electrode is called potentialdifference Potential difference cause current to flow; another name for potential difference is _. electrode amps voltage electricity Matching mechanical energy associated with movement; can be potential or kinetic radiant energy of electromagnetic radiation; 'light' energy electrical energy of moving electrons chemical energy of a compound that changes as its atoms are rearranged nuclear energy that comes from changes in the nucleus of an atom thermal energy due to the average kinetic motion of particles that make up an object Fill in the energy chains for these devices: Chemical cell: chemicalenergy --> electricalenergySolar cell: radiantenergy --> electricalenergyPlants growing: radiantenergy (sun) --> chemicalenergy (plants) What is the importance of anelectrolytein a chemical cell? electrolytes act as wires as electrodes it is an acid it has extra electrons for the reaction In this lab, which of the following did we not test as an electrode? zinc copper carbon sodium According to class 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
