8 Which equation represents the standard enthalpy change of formation of ethanol, $$ C _ { 2 } H _ { 5 } O H ? $$ B$$ 2 C ( g ) + 3 H _ { 2 } ( g ) + \frac { 1 } { 2 } O _ { 2 } ( g ) \rightarrow C _ { 2 } H _ { 5 } O H ( l ) $$$ 2...
The reader should not expect completeness of precedent or literature citations. To be truly "proved," paradigms require extensive rigor and/or documentation. Paradoxes are easier to show if what is written is really what has been meant. Just as travelogs are not atlases or sociohistorical ...
