Estimate the enthalpy change for the combustion of one mole


Question- Estimate the enthalpy change for the combustion of one mole of acetylene, C2H2, to form carbon dioxide and water vapor. BE(C?H) = 456 kJ/mol)

BE(C?C) = 962 kJ/mol

BE(O=O) = 499 kJ/mol

BE(C=O) = 802 kJ/mol

BE(O?H) = 462 kJ/mol

Answer choices:

A. +653 kJ/mol

B. ?155 kJ/mol

C. +1010 kJ/mol

D. ?1759 kJ/mol

E. ?1010 kJ/mol

I am stuck in between this question please help me out
