The corrosion rate of a metal is a function of many factors like:
-fluid to which the metal is exposed (chemical composition, concentration..)
-temperature
-flow velocity
-time of exposure
so it's not possibile to give a simple answer
I think it scratches, the only web page that gave me any help was one that was selling a mild steel scratch brush on E-bay...

No - not under normal conditions. However, if it has cathodic current applied to it or it is immersed in alkali such as concrete.
no
Yes, it is.
Yes, the mild steel under the plating is magnetic. The coating only prevents corrosion.
Alloys can add corrosion resistance to a metal
Mild steel, not copper.
Somebody is doing a Btec. Go do some research like the rest of us mugs.
steel is the alloy of iron and carbon , so mild steel is an ferrous alloy
Many stainless steels are stronger than mild steel. Stainless steel is also corrosion resistant to many different environments where mild steel is not.
Many stainless steels are stronger. It's also more corrosion resistant.
Yes, the mild steel under the plating is magnetic. The coating only prevents corrosion.
The fracture toughness, or the property that describes the ability of a material containing a crack to resist fracture, of mild steel is around 50 K (where 'K' is the stress intensity factor).
Per the attached related link, the density (hence weight) of stainless is slightly more than the mild carbon steel. Using about 8.03/7.84 ratio of density, for the same volume of material the stainless will weigh 2.4 % more.
It has a quantity of Chromium (usually around 10%) added during the smelting process. The Chromium forms a 'film' on the surface - preventing rusting.
mild steel is heavier

Alloys can add corrosion resistance to a metal
Zincalume is steel with a thin coating of a zinc and aluminium mix to resist corrosion. Most silver/grey "metal colored" corrugated roof sheeting is zincalum these days.
Aluminium is very light. It can suffer very intense corrosion, but that leads to one of its greatest strengths: the corrosion forms a very well-formed protective oxidant layer (Al2O3) which prevents the further corrosion. In that way, the low-resistance of aluminum to its initial corrosion, results to one of the better corrosion-protected metals in industry.
