Answer:
the enthalpy of the bond between chlorine and ozone is the 122,8 kj
Explanation:
Review Hess's Law
Inverse equation (1): Cl (g) + 2O2 (g) ==> Cl) (g) + O3 (g) ∆H = +122.8 kJ / mol (note change in sign of ∆H)
Copy equation (2): 2O3 (g) ===> 3O2 (g) ∆H = -285.3 kJ / mol
Add the 2 equations: 2O3 (g) + Cl (g) + 2O2 (g) ===> Cl)) g) + O3 (g) + 3O2 (g) and cancel common species
When you do this, you end up with the desired equation
Answer:
In chemistry, an element is a pure substance which cannot be broken down by chemical means, consisting of atoms which have identical numbers of protons in their atomic nuclei. The number of protons in the nucleus is the defining property of an element,
