Wire brush or steel wool.
Iron wool gains mass when it is burnt because the oxygen in the fire oxidizes and rusts the iron. The additional oxygen molecules on the iron wool in the form of rust increases the mass of the wool.
a smell of burnt hair comes, i think
You could iron wool with a hot-enough iron to set it on fire.
1. Is clean wool hydrophobic or hydrophilic? Why?
steel is made from a mixture of iron and carbon so yes, steel wool definitely has iron in it
The Flourine goes Grey and starts to dissolve into the Iron Wool
Not burning, but a melting process.
iron oxide. the most common types are iron oxide (FeO), iron (II) oxide (Fe2O3), and iron(III) oxide (Fe3O4).
in this demonstration experiments iron wool is heated in the presence of chlorine gas,and the vapour of bromine and iodine.Exothermic reaction occur,causing iron wool to glow.Iron wool rust and produced coloured vapours. 2fe+I2=2FeI2
Yes.
Because the surface area of iron wool is higher, the area exposed to acid is higher.
