ordinary mixing is a physical change but when you get to heat them products are formed and it is a chemical change.
The balanced chemical equation for the reaction of iron (Fe) with copper (Cu) is: Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)
The balanced chemical equation for the formation of Fe2O3 from Fe and O is: 4Fe + 3O2 -> 2Fe2O3
When heating steel wool (Fe) with S8, the ionic equation can be represented as Fe(s) + S8(s) -> FeS(s), where iron reacts with sulfur to form iron sulfide.
When heated, iron filings (Fe) react with sulfur (S) to form iron sulfide (FeS). The chemical equation for this reaction is: Fe + S -> FeS.
chemical equation of heated iron and sulfur is as follows. FeS can be obtained by the heating of iron and sulfur:Fe + S → FeS.

Fe + S = FeS
When heated, iron filings (Fe) react with sulfur (S) to form iron sulfide (FeS). The chemical equation for this reaction is: Fe + S -> FeS.
The balanced chemical equation for heating magnesium metal is: 2Mg(s) + O2(g) -> 2MgO(s)
chemical equation of heated iron and sulfur is as follows. FeS can be obtained by the heating of iron and sulfur:Fe + S → FeS.
Iron(III) hydroxide is 'Fe(OH)3 ' As you have given it , it is incorrect. FeO(s) + 2H2O(l) = Fe(OH)3 + (3/4)H2(g) 4FeO(s) + 8H2O(l) = 4Fe(OH)3(aq)+ 2H2(g) Done!!!!!
This reaction is: Fe(s) + CuSO4(aq)----- --> FeSO4(aq) + Cu(s)
Fe + S -------> Fe + S . 8 8 8 8
Fe + S = FeS or 2Fe +3S = Fe2 +S3
FeS is not a chemical equation but a chemical formula; FeS is the chemical formula of iron sulfide.
