Flammability test of ethyne
WebAcetylene is often found as the fuel in torches—it burns brilliantly in air with a very hot flame due to its very high heat of combustion (1300 kJ/mole). The reaction of calcium carbide and water produces acetylene and a chalky suspension of calcium hydroxide. CaC 2 (s) + 2H 2 O(l) Equation 1→ C 2 H 2 (g) + Ca(OH) 2 WebWhat are the uses of Ethyne?
