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 harness the electrical energy available from the electron transfer in a redox reaction to perform useful electrical work. The key to gathering the electron flow is to separate the oxidation and reduction half-reactions, connecting them by a wire, so that the electrons must flow through that wire.he above figure points out that the electrode in the oxidation half-cell is called the anode and the electrode in the reduction half-cell is called the cathode. A good mnemonic to help remember that is . The Red Cat ate An Ox  meaning reduction takes place at the cathode and oxidation takes place at the anode.
