<span>We know that protons gives positive charge, neutrons no charge and electrons negative, then +14 - 12 = +2
So the charge of the atom is sign positive and magnitude 2</span>
The value of the Gibbs free energy shows us that the reaction is spontaneous.
<h3>What is the Gibbs free energy?</h3>
The Gibbs free energy is a quantity that helps us to be able to determine the spontaneity of a reaction.
In order to obtain the Gibbs free energy, we must obtain the Ecell as follows; 0.799V - (-0.402V) = 1.201 V
Now;
△G = -nFEcell
△G = -(2 * 96500 * 1.201)
△G = -232kJ/mol

Answer:
1.13 × 10⁶ g
Explanation:
Let's consider the reduction of aluminum (III) from Al₂O₃ to pure aluminum.
Al³⁺ + 3 e⁻ → Al
We can establish the following relations:
- 1 Ampere = 1 Coulomb / second
- The charge of 1 mole of electrons is 96,468 c (Faraday's constant)
- 1 mole of Al is produced when 3 moles of electrons circulate
- The molar mass of Al is 26.98 g/mol.
The mass of aluminum produced under these conditions is:
