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 WebJan 26, 2010 · In this part of the experiment, you will prepare acetylene (ethyne) and test its combustibility. Fill a 400-mL beaker nearly full of tap water. Fill three test tubes (18x150 mm) with water as follows: Tube #1 completely full; Tube #2 with15 mL water; and Tube #3 with 6 mL water.
