Consider Ms. Legaspi's second favorite holiday radio station, KOST 103.5 FM. The number 103.5 is a
frequency in megahertz (millions of Hertz). Calculate
the wavelength and the energy of electromagnetic waves
from your favorite radio station.
Hint: Usc 103.5 x 106 Hz as your valuc for
frequency.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
