Acetylene gas (ethyne; HC?CH) burns in an oxyacetylene torch to produce carbon dioxide and water vapor, and the heat needed to weld metals. The heat of reaction for the combustion of acetylene is -1259 kJ/mol. A. Calculate the C?C bond energy, and compare your value with that in the table. B. When 628.0 g of acetylene burns, how many kilojoules of heat are given off?C. How many grams of CO2 form?D. How many liters of O2 at 298 K and 22.9 atm are consumed?
