3. A metallurgist wants to goldplate a thin sheet with the following dimensions: 1.5 in, x 8.5 in. x 0.0012 in. The gold plating must be 0.0020 in. thick. (a) How many grams of gold (p = 19.3 g/cm') are required? (b) How long will it take to place the sheet from AuCN using a current of 7.00 A? Assume 85% efficiency.

Look at the three infrared spectra in Figures C to D and answer the following questions (a) Are any of the spectra that of an alcohol? If so, which? What absorption pattern(s) at what wavelength(s) identifies an alcohol? (b) Are any of the spectra that of a compound containing a benzene ring? If so, which? What three absorption patterns at what wavelengths show that a compound has a benzene ring? (c) Are any of the spectra that of a compound containing only carbons and hydrogens? If so, which? Benzene rings contain only carbons and hydrogens. Might the spectrum or spectra you chose for your answer above indicate a benzene ring? (Tell what absorption patterns are present or not present that would support your answer.)
