Question

Quizplus · Accepted Answer

To calculate the energy used, first determine the moles of magnesium produced, then calculate the charge required using Faraday's laws, and finally convert the charge to energy using the given voltage. The energy in joules is then converted to kilowatt-hours. The correct calculation leads to 34.7 kWh.
