Question

Guess who i am?i) i am a cheap metal but highly reactive. therefore, i sacrifice myself to save objects made of iron.

Answer 1

Dear Student,

◆ Answer -

Zinc

● Explanation -

• Galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting.
• In this process, zinc coating reacts with air to form zinc oxide which prevents O2 from reacting with iron.
• For this to occur, metal to be coated must be more reactive than iron.
• As Zn is more reactive than Fe, it is used in galvanising.
• Because of its low reactivity, Cu can't be used for galvanizing.

Hope I was useful...

Answer 2

Answer:

i am a cheap metal but highly reactive. therefore, i sacrifice myself to save objects made of iron.

The metal is Zinc.

Explanation:

Rusting of iron can be prevented by galvanization process.

• in this process, a  thin layer of zinc is deposited on the iron metal.
• The thin layer of zinc metal protects iron from rusting because Zinc metal does not corrode on exposure to damp air.
• Zinc is reactive metal
• The action of zinc with air forms a Zinc oxide all over it
• This zinc oxide is hard and impervious to air and hence prevents rusting
