When carbon ( ) reacts with concentrated sulfuric acid ( ) and is heated, the reaction produces carbon dioxide ( ) and sulfur dioxide ( ) gases. The sulfuric acid provides the sulfur that reacts with carbon to form sulfur dioxide, while the carbon dioxide is a product of the oxidation of carbon.

Copper matte is primarily composed of copper and iron sulphides. It is obtained during the process of smelting copper ores. The smelting process involves heating copper ores in the presence of a flux to separate impurities. The resultant mixture, known as matte, typically contains copper and iron in the form of their sulphides ( and ).
