The free radical is CIO intimately involved in reactions that lead to the destruction of ozone in the stratosphere. Given that a chlorine-oxygen bond in CIO2(g) has an enthalpy of 243 kj/mol , an oxygen-oxygen bond has an enthalpy of 498 kj/mol , and the standard enthalpy of formation of CIO2(g) is DH f=102.5 kj/mol , use Hess's law to calculate the value for the enthalpy of formation of CIO (g)
Calculate the concentrations of the protoneated and unprotonated forms of bromothymol blue in 100 mL of a pH 8.1 buffer solution to which 1.0 mL of 0.005 M solution of bromothymol blue in 80% wate/20%ethanol has been added.
