4) A bottle containing numerous pieces of an unknown metal was left on the counter in lab. After a bit of investigation, it was deduced that the metal must be one of three pure elements: magnesium, iron, or silver. A student worker dropped a piece of the metal into a copper (II) nitrate solution and observed that after several minutes the blue color of the solution faded, and the metal was coated with a reddish-brown material. Next, the student dropped another piece of the metal into a zinc nitrate solution. This time, no significant changes were observed. a. Develop a flow chart that matches the steps performed by the student worker and will allow identification of the unknown metal. Mg, Fe, Ag

The present average concentration (mass percent) of magnesium ions in seawater is 0.13%. A chemistry textbook estimates that if 1.00 × 108 tons Mg were taken out of the sea each year, it would take one million years for the Mg concentration to drop to 0.12%. Do sufficient calculations to either verify or refute this statement. Assume that Earth is a sphere with a diameter of 8000 mi, 67% of which is covered by oceans to a depth of 1 mi, and that no Mg is washed back into the oceans at any time.
