Disconnecting means for air-conditioning or refrigerating equipment can be installed the air-conditioning or refrigerating equipment, but not on panels that are designed to allow access to the equipment, and not over the equipment nameplate.

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.
