Why is corrosion considered a chemical property?

It can be easily reversed by physical means.

It only affects the surface atoms of a metal.

It is visible to the naked eye.

It involves an interaction between two substances resulting in a change on a molecular level. (correct)

Which scenario best illustrates corrosion as a chemical property?

Rusting of steel due to exposure to oxygen (correct)

A metal getting scratched by a rough surface

Melting of ice into water

Formation of rust-colored stains on a metal surface

Why does it take more feathers than sugar to make a kilogram despite both having the same mass?

Sugar has more mass per unit volume than feathers.

Feathers have less volume compared to sugar. (correct)

Feathers are denser than sugar.

Sugar is less dense than feathers.
