When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

What should the power status of a circuit be when measuring resistance with an ohmmeter?

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.
