What is the balanced chemical equation for the reaction of iron (Fe) and sulfur (S) to form iron(III) sulfide?
gpt
2 Fe + 3 S ➝ Fe2S3
Explanation: The law of conservation of mass requires that the number of atoms of each element is the same on both the reactant and product sides of a chemical equation, resulting in 2 Fe + 3 S forming 1 unit of Fe2S3.
