PLEASE NO BOTS lol Ethyne or acetylene is also used in cutting torches. The acetylene is combined with pure oxygen producing a flame with a temperature of 6332 °F or 3500 °C. The combustion of acetylene in the presence of excess oxygen yields carbon dioxide and water:

2C2H2 (g) + 5O2 (g) --> 4CO2 (g) + 2H2O (l)
