Question

Methane burns in oxygen. the equation below represents this reaction

CH^4 + 2O^2 -> CO^2 + 2H^2O

O=O bond = 500 k/J
C=O bond = 800 k/j
H-O bond = 460 k/J

1) Calculate the bond energy in 1 mol of carbon dioxide?
2) Calculate the bond energy in 2 mol of H2O?

Answer 1

B.E. CO2 = 2*C=O = O=C=O = 2*800 kJ/mol = ?

B.E. 2*H2O = 4*OH = 4*460 kJ/mol = ?
