Match each copper-containing ore with its corresponding chemical formula.

Malachite matches

\text{CuCO}_3\cdot\text{Cu(OH)}_2

, Copper pyrites matches

\text{CuFeS}_2

, Cuprite matches

\text{Cu}_2\text{O}

, and Chalcocite matches

\text{Cu}_2\text{S}

Each copper ore correctly maps to its characteristic chemical formula: Malachite is basic copper carbonate

\text{CuCO}_3\cdot\text{Cu(OH)}_2

; Copper pyrites is copper iron disulfide

\text{CuFeS}_2

; Cuprite is copper(I) oxide

\text{Cu}_2\text{O}

; and Chalcocite is copper(I) sulfide

\text{Cu}_2\text{S}

Identify the chemical nature of Malachite

Malachite is a basic carbonate mineral of copper with the formula

\text{CuCO}_3\cdot\text{Cu(OH)}_2

Basic copper carbonate consists of copper carbonate and copper hydroxide in a 1:1 mole ratio.

Identify the chemical nature of Copper pyrites

Copper pyrites (chalcopyrite) has the formula

\text{CuFeS}_2

It is the chief ore of copper containing both iron and copper sulfides.

Identify the chemical nature of Cuprite

Cuprite is copper(I) oxide,

\text{Cu}_2\text{O}

Cuprite is a red oxide ore containing copper in the +1 oxidation state.

Identify the chemical nature of Chalcocite

Chalcocite is copper(I) sulfide,

\text{Cu}_2\text{S}

Chalcocite is a dark sulfide ore of copper.
