Answer 1

Mixture describes a piece of pure gold

Answer 2

Answer: Element

Step-by-step explanation:

Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Example: Air

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water
`H_2O`

Solution is a homogeneous mixture of a solute and a solvent. Example: salt in water

Element is a pure substance which is composed of atoms of similar elements. It can not be decomposed into simpler constituents using chemical reactions.Example: Gold
`(Au)`

Thus pure gold is an element.
