The chemical reaction is:Pb(NO3)2 + Fe SO4 = PbSO4(s) + Fe(NO3)2
Iron (Fe) and Sulphur (S) are no more unstable than any other non-radioactive elements.
Fe is used as chemical symbol for elementary iron (Latin: Ferrum)S is used as chemical symbol for elementary sulfur (or sulphur)
The sunshine's warmth is the most commonly observed example of heating by radiant energy.
Fe(s) + 3AgNO3 ==> Fe(NO3)3 + 3Ag(s)
ordinary mixing is a physical change but when you get to heat them products are formed and it is a chemical change.
Fe + S -------> Fe + S . 8 8 8 8
When temerature is high enough: Fe + S --> FeS (+ heat, energy)
In laboratory settings, you can make react a mixture of powdered sulphurand iron filings by heating. The end product is Ferrous Sulfide;Fe + S ----> FeSIron sulfides in nature are Pyrite and Marcasitewhose formula is; FeS2 .
+3 for Fe -2 for S
When CS2 is added to reaction mixture Fe + S = FeS , it would dissolve the excess 'S' leaving the solids Fe and FeS without any change.
+3 for each Fe, -2 for each S
Fe(s) + 2CH3COOH(aq) = Fe(CH3COO)2(aq) + H2(g)
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.

The most common alloy is the Swedish Kanthal (Fe, Cr,Al).
