6 Atoms!
Mg = 1 atom.
O = 4 atoms.
A = 1 atom.
Molten barium chloride is separeted
into two species :
BaCl₂(l) → Ba(l) + Cl₂(g),
but first ionic bonds in this salt are separeted because of heat:
BaCl₂(l) → Ba²⁺(l) + 2Cl⁻(l).
Reaction of reduction at cathode(-): Ba²⁺(l) + 2e⁻ → Ba(l).
Reaction of oxidation at anode(+): 2Cl⁻(l) → Cl₂(g) + 2e⁻.
<span>The anode is positive and the cathode is negative.</span>
The answer should be C. Technology is the application of the knowledge gained by science.
