for transportation and electricity?
![15) CuClz dissolves in water and the solution is green in color. That means that: a. its reduced to Cu metal b. it will turn yellow with time c. it transmits the light between 400 and 700 nm d. it absorbs blue light and red light e. dilution will not alter the color Bonus: Draw an absorption spectrum (diagram of absorbance vs. wavelength) of CuCl2 solution 16) Volatility is a property of a liquid to evaporate to form gas. Many substances that have distinct odors or aromas have volatile substances in them. Identify and record the physical properties of the organic compound below that contribute to its characteristic aroma. [Ref.
