Answer:
2.14 x 10^-10 M
Explanation:
[H+] = 10^(-pH) = 10^-9.67 = 2.14 x 10^-10 M
<span>The enthalpy of the reaction in an aqueous
solution can be determined by taking the difference between the summation of
enthalpies of the products multiplied to their respective stoichiometric
coefficient and the summation of enthalpies of the reactants multiplied to
their respective stoichiometric
coefficient. In this case, the equation is -241(6) + -393.5 (5) -[-119.9] equal to 641.4 kJ </span>
