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.
Electrochemical cell (Galvanic Cell). Electrolytic cell. A Galvanic cell converts chemical energy into electrical energy. An electrolytic cell converts electrical energy into chemical energy. Here, the redox reaction is spontaneous and is responsible for the production of electrical energy. The redox reaction is not spontaneous and electrical energy has to be supplied to initiate the reaction.
