The correct answer is
D).
Dissolution and dissociation of aluminum chloride:
AlCl₃(s) → Al³⁺(aq) + 3Cl⁻(aq)
The cation of aluminum is hydrolyzed:
Al³⁺ + 2H₂O ⇄ AlOH²⁺ + H₃O⁺
AlOH²⁺ +2H₂O ⇄ Al(OH)₂⁺ + H₃O⁺
Al(OH)₂⁺ + 2H₂O ⇄ Al(OH)₃ + H₃O⁺
Answer:
five electrons
Bromine (Z=35), which has 35 electrons, can be found in Period 4, Group VII of the periodic table. Since bromine has 7 valence electrons, the 4s orbital will be completely filled with 2 electrons, and the remaining five electrons will occupy the 4p orbital
