Question

Balance the following chemical equation by providing the correct coefficients

Answer 1

the coefficients would be 2 3 1 6

Answer 2

Answer:

2FeBr₃ + 3Na₂S → 1Fe₂S₃ + 6NaBr

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.
