If you were to apply a substance to prevent rust on a steel hammer, which of the following would you expect to protect the iron using the same mechanism as the polymer coating? Select all that apply. Rubber B. Copper C. Vinegar Latex paint E. Wax Zinc QUESTION 5 2 points Save Answer Identify the correct statement (s) with regards to the last part of Experiment 6: Zinc in Contact with Magnesium A. As the reaction proceeds, Copper metal is deposited on the exposed surface of the nail. B. Magnesium forms a physical barrier prevent the Cu(NO3)2 solution from coming into contact with the zinc-plated galvanized na Aluminum metal cannot be used instead of magnesium to prevent corrosion of zinc under the same conditions. D. Magnesium metal could be used as a suitable coating for both galvanized and non-galvanized nails to protect both iron and zinc from corrosion. Magnesium is oxidized from Mg(s) to 2+ when in contact with the Cu(NO3)2 solution MgExplanation / Answer
A)
prevent rust in steel hammer...
polymer coating --> there will be a top cover in the acutal material
so..
use either:
Rubber, latex paint or Zinc (it will act as a covering material)
Q5
Zn + Mg --> Mg+2 and Zn(s)
therefore
D) is the best answer that suits this, since Mg+2 will oxidize before... also we form a crust in the Zinc material
