Given:  Calculate the standard enthalpy of formation of CuO(s).

Quizplus · Accepted Answer

The given alphanumeric string is not relevant to solving this problem. The standard enthalpy of formation of CuO(s) is -155 kJ/mol. This value can be found in a standard thermodynamics table or by calculating the enthalpy change of the reaction:

Cu(s) + 1/2 O2(g) -> CuO(s)

Using the standard enthalpies of formation for Cu(s) and O2(g), which are both 0 kJ/mol, and the standard enthalpy of formation of CuO(s) (-155 kJ/mol), we can calculate the standard enthalpy change of the reaction:

Delta H° = (1 mol CuO)(-155 kJ/mol) - (1 mol Cu)(0 kJ/mol) - (1/2 mol O2)(0 kJ/mol) = -155 kJ/mol

Given: Calculate the Standard Enthalpy of Formation of CuO(s)
