Assume you are looking at a periodic table that is not color coded.
a. describe where to look on the periodic table to find elements which have similar chemical properties.
b. explain why they have similar properties.
c. name three elements that have those similarities.

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.
