**Calculate the standard enthalpy change for the following reaction at 25 °C. Standard enthalpy of formation values can be found in this table. **
MgCl2(l) +H2O(l)=MgO(s)+ 2HCL(g)
Answer:
Calculate
HRxn = Hprod - Hreact
HRxn = H-MgO + 2*H-Hcl) - (H-MgCl2 + H-H2O(l)
HRxn = (-601.6 + 2*-92.3) - ( -641.8 + -285.8)
Hrxn = 141.4 kJ/mol.
