Question

The formula of malachite ore is _______.

Answer 1

• Malachite is a green copper carbonate hydroxide mineral with a chemical composition ${\mathrm{Cu}}_2{\left(\mathrm{OH}\right)}_2\left({\mathrm{CO}}_3\right)$.
• It was one of the first ores used to produce copper metal.
• Malachite has been used as a gemstone and sculptural material for thousands of years and is still popular today.
• Malachite has a green colour that does not fade over time or when exposed to light.

Hence, the formula of malachite ore is $\mathrm{Cu}{\left(\mathrm{OH}\right)}_2{\mathrm{CuCO}}_3$.
