Please correct answer and don't use hand rating
AB(s) + CD(s) +H2O--> AD(s) + C(
(aq) + B' (aq)
If 10.0g AB (MM=102g/mol) and 10.0g CD (MM-77g/mol) are added to
1000.0g water and allowed to dissolve, react and precipitate and the observed
temperature change was 8K, use the information below to solve the dHlattice for
AD in kJ/mol
*Assume solution is similar to pure water for heat capacity*
dHlattice AB = 409kJ/mol
dHlattice CD = 432kJ/mol
dHhydration A-196kJ/mol
dHhydration B-216.6kJ/mol
dHhydration C₁ =-74.8kJ/mol
dHhydration D-74.6kJ/mol
