Use average bond energies to calculate the energy released when 1 mole of acetylene gas (ethyne, C2H2) reacts completely with O2(g) to form gaseous products. Use the information in the Table of Bond Enthalpies which is in the Chemistry Tables link to the left.

C(triple-bond) = 835kJ/mol
C-H = 413kJ/mol
O-O = 146kJ/mol
