Mike wants to galvanize iron to protect it from rusting. Which metal should he use? A
platinum
B.
aluminum
C.
copper
D.
zinc
E.
tungsten

D. Zinc.

Explanation:

Galvanization is a metal-coating process which involves the application of a thin layer of zinc to an iron or steel, so as to prevent rusting or corrosion.

The zinc metal protects the iron from rusting by sealing the surface of the iron and thus, preventing weathering and oxidation.

Hence, if Mike wants to galvanize iron to protect it from rusting. The metal he should use is zinc (Zn) because a coating of zinc would protect the iron (Fe) by corroding first when exposed to moisture or the atmosphere.

14 days is the half-life of phosphorus-32

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
