Answer:
The given equation is Balanced.
Explanation:
AlBr₃ + 3K → 3KBr + Al
The balanced equation consist of equal number of atoms of elements in reactant and product side.
The given equation is balanced because one aluminium, three bromine and three potassium atoms are present on both side of equation.
If element A has an ionic charge of +2 and element B has an ionic charge of -3
then the reaction is given as: A^2+ + B^3- --------------------> A3B2
the compound formed is : A3B<span>2</span>
