In the hall-heroult process, a large electric current is passed through a solution of aluminum oxide (a12o 3) dissolved in molten cryolite (na3aif6) ,resulting in the reduction of the ai�3 to pure aluminum. suppose a current of 6800.a is passed through a hall-heroult cell for 54.0 seconds. calculate the mass of pure aluminum produced. be sure your answer has a unit symbol and the correct number of significant digits.

34.2 g

Explanation:

In the Hall-Heroult process, Al³⁺ (from Al₂O₃) is reduced to Al. The reduction half-reaction is:

Al³⁺ + 3 e⁻ ⇒ Al

We can establish the following relations:

Suppose a current of 6800 A is passed through a Hall-Heroult cell for 54.0 seconds. The mass of Al produced is:

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
