Metals Covalently Bonded to Benzene, I've noticed that my book does not mention metals as a possible substituent for mono-substituted benzenes, but it doesn't begin to explain why
Consider the following specific heats: copper, 0.384 J/g·?C; lead, 0.159 J/g·?C; water, 4.18J/g·?C; glass, 0.502J/g·?C. If the same amount of heat is added to identical masses of each of these substance
