Hematite
a reddish-black mineral consisting of ferric oxide. It is an important ore of iron.
Carbon is a reducing agent ? Why
Because it is a non-metal and it combines with oxygen and forms its gaseous non-metallic oxides
Reduction is what
It is the process of removing oxygen form iron.
Redox reaction
A reaction where Oxidation occurs at the same time reduction.
Oxidation
Is the loss of electrons
Reduction
Is the gaining of electrons.
Alloy
Alloy means the mixing of two metals.
Ways to stop oxidization ?
Ways to stop oxidization of the barrier method galvanizing and sacrificial protection.
what is galvanizing
galvanizing is when zinc is added to the outside layer.
