The surface of the continental united states has an area of about 8 x 10^6 km^2 and an average elevation of about 500 m (above sea level). the average yearly rainfall is 75 cm. the fraction of this rainwater that returns to the atmosphere by evaporation is 2/3; the rest eventually flows into the ocean energy of the water-earth system associated with that flow could be fully converted to electrical energy, what would be the average power? (the mass of 1 m^3 of water is 1000 kg.)

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
