Answer 1

Answer:

X = 350 kJ/mol

Explanation:

According to the question:

Energy needed when breaking bonds  +  1640 kJ/mol   =   Energy released when forming bonds

∴ 2 (C - C) + 8 (C - H) + 5 (O = O) + 1640 = 6(C = O) + 8(O - H)

⇒ 2 (X) + 8 (410) + 5 (500) + 1640 = 6 (740) + 8 (460)

⇒ 2X  +  7420  =  8120

⇒ 2X = 700

⇒ X = 350 kJ/mol
