Answer:
554.86kj
Explanation: Since 1 mole of CaC2=15.14kj yield 1mole of C2H2
The enthalpy change of H2O is 2*285=570
570+-15.14=554.86kj
Hence Hp is 554.86kj
He=Hp
Table salt = ionically bonded molecule, sodium transfers one valence electron to chloride, NaCl
Table sugar = covalently bonded molecule
