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.
Ernest Z. An exergonic reaction is one in which #Î´G# increases, and an endergonic process is one in which #Î´G# decreases. #Î´G# is the energy that is available to do work. An example of an exergonic reaction that occurs in our body is cellular respiration. This reaction releases energy that the cell uses for its activities. The above value of #Î´G# is for the conditions found within a cell. The tabulated value of #Î´G^Â°# = -2870 kJ refers to standard conditions (1 atm, 25 Â°C).
