The answer is C, -166 kJ. How do I calculate this?
26. Phosphoric acid can be prepared by the reaction of P O1o with water as given by the following balanced chemical equation. P4Oio(s) +6H20)4H3PO(aq) When 25.8 g of H3POs (98.0 g/mol) is produced, 10.9 kJ of heat is evolved. Calculate AH for the overall reaction. A. -27.4 kJ B. 105 kJ C. -166 kJ D. 41.6 k
