Answer 1

Answer:

Explanation:

Alloys are homogeneous mixtures. Pure gold is referred to as 24-karat gold.  Propane is a chemical compound so it is a pure substance. ... Aluminum is a chemical element so it is a pure substance.

Gold (symbol Au) is an Element so it is pure.

However has has been said, very pure Gold is too soft for most purposes.

To give an example pure Gold 24 carat is so soft you can scratch it with your fingernail.

I may add that soft does not mean light, Gold is very heavy / dense it has a density of 19.32 g per cm sq. For comparison Iron or steel had a density of around 7.2 g per cm sq
