Define the following terms.
(1) Mineral
(1) Ore
h) Gangue
Name two metals which are found in nature in the free state
What chemical process is used for obtaining a metal from its oxide?...
​

Answer 1

Explanation:

mineral-

In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure, that occurs naturally in pure form

ore-

Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals

gangue-

In mining, gangue (/ɡæŋ/) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit.

gold, silver

The chemical process used for obtaining a metal from its oxide is reduction. In this process, metal oxides are reduced by using suitable reducing agents such as carbon or by highly reactive metals to displace the metals from their oxides.
