oops pls forgive me I accidentally did the wrong question.
1.formular masses
2. molecular masses

Answer:
Chemical equation:
3S(s) + 2Fe(s) → Fe₂S₃(s)
Explanation:
Iron metal react with solid sulfur and produced slid iron(III) sulfide.
The chemical reaction is given below:
Chemical reaction:
S + Fe → Fe₂S₃
Balanced chemical equation:
3S + 2Fe → Fe₂S₃
Balanced chemical equation with physical state:
3S(s) + 2Fe(s) → Fe₂S₃(s)
Ionic equation can not be written because all reactant and products are in solid form.
