8Fe + S8 - 8FeS
molecular equation: CuSO4 (aq)+Fe (s) --> Cu(s) + FeSO4(aq) net ionic equation: Cu2+(aq) + Fe2+ (s) --> Cu2+(s) + Fe2+(aq) spectator ion: Sulfate Ion (SO42-)
When the steel wool burns, it is oxidized and thus this is a chemical change.
Fe + H2SO4(aq) -> FeO + H2O + SO2
The steel wool gets wet. If you take the steel wool out (into the air) again it will rust.
WOOD + OXYGEN > CARBON DIOXIDE + WATER

steel wool is steel made from wool, so it would be neither
thin steel wool
4 Fe (s) + 3 O2 (g) --------> 2 Fe2O3
the wool does not rust
Steel wool is a mixture.
The steel wool gets wet. If you take the steel wool out (into the air) again it will rust.
Steel wool is a Mixture-Mechanical
WOOD + OXYGEN > CARBON DIOXIDE + WATER
CuSO4 (aq) + Fe (s) -> FeSO4 (aq) + Cu (s)
