Answer:
2FeBr₃ + 3Na₂S → 1Fe₂S₃ + 6NaBr
Step-by-step explanation:
SOLUTION :-
Balance the equation by hit & trial method , and you'll get the answer :-
2FeBr₃ + 3Na₂S → 1Fe₂S₃ + 6NaBr
VERIFICATION :-
In the reactant side of the equation :-
- Number of Fe atoms = 2×1 = 2
- Number of Br atoms = 2×3 = 6
- Number of Na atoms = 3×2 = 6
- Number of S atoms = 3×1 = 3
In the product side of the equation :-
- Number of Fe atoms = 1×2 = 2
- Number of S atoms = 1×3 = 3
- Number of Na atoms = 6×1 = 6
- Number of Br atoms = 6×1 = 6
Number of atoms of all elements are same in both reactant & product side of the equation. Hence , the equation is balanced.
