Answer: kJ/mol
Explanation: <u>Enthalpy</u> <u>Change</u> is the amount of energy in a reaction - absorption or release - at a constant pressure. So, <u>Standard</u> <u>Enthalpy</u> <u>of</u> <u>Formation</u> is how much energy is necessary to form a substance.
The standard enthalpy of formation of HCl is calculated as:
→
Standard Enthalpy of formation for the other compounds are:
Calcium Hydroxide: -1002.82 kJ/mol
Calcium chloride: -795.8 kJ/mol
Water: -285.83 kJ/mol
Enthalpy is given per mol, which means we have to multiply by the mols in the balanced equation.
Calculating:
So, the standard enthalpy of formation of HCl is -173.72 kJ/mol

Explanation:
Motor weight average number
Poly condensation degree dependent on the average number of molecular weights is as follows:
All monomer module, in this case, is propylene
Sunrise. Unit Wt = Mol. Propylene weight
