Do not count mispronunciations of difficult proper nouns in the oral reading pas-. sages as errors. You may pronounce these for the children if necessary. Also, do not. count as errors dialectical equivalents (nonstandard dialects); however, these should. be noted.
A galvanic cell is also called a voltaic cell. The spontaneous reactions in it provide the electric energy or current. Two half cells can be put together to form an electrolytic cell, which is used for electrolysis. In this case, electric energy is used to force nonsponaneous chemical reactions.
Galvanic Cells, 2 Consider the galvanic cell pictured below, featuring two electrodes suspended in a solution of CdCl 2. One electrode is Cd, and the other is metallic Ag coated with solid AgCl.The net reaction is composed of a reduction and an oxidation, each of which is called a half-reaction.alvanic Cells, 4 To make a working cell, the reactants are separated into two half-cells which are connected with a salt bridge. The salt bridge is a U-shaped tube ï¬lled with a gel containing a high concentration of KNO 3 (or other electrolyte that does not affect the cell reaction).
