zloy xaker [14]

Answer:

Free energy change of the reaction is +98.83 kJ/mol.

Explanation:

The dissociation reaction of mercury(I) aqueous solution is as follows.

Hg_{2}Cl_{2}(s)\rightarrow Hg_{2}^{2+}(aq)+2Cl^{-}(aq)

The standard free energy of the reaction is as follows.

\Delta G_{rxn}^{o}=m\Delta G^{o}(products)-n\Delta G^{o}_{reactants}

=[(1\times \Delta G^{o}_{f(Hg_{2}^{2+})})+(2\times \Delta G^{o}_{f(Cl^{-})})-(1\times \Delta G^{o}_{f(Hg_{2}Cl_{2})})]

=[(1\times 153.5+2\times -131.25)-(1\times -210.78)]kJ=+101.78kJ

Gas\,constant"R"=8.314\times 10^{-3}kJK^{-1}mol^{-1}

Temperature=25^{o}c=25+273=298K

Free\,energy\,change\,of\,the\,reaction=\Delta G=\Delta G^{o}+RT\,lnQ

\Delta G=\Delta G^{o}+RT\,ln([Hg_{2}^{2+}][Cl^{-}]^{2})

=(101.78kJ)+8.314\times 10^{-3}kJK^{-1}mol^{-1}\times298K ln((0.926)(0.573)^{2})

=(101.78kJ)+(-2.95kJ)=+98.83kJ/mol

Therefore, Free energy change of the reaction is +98.83 kJ/mol.

Give one possible explanation for the car’s distance from the starting location at 9:00 a.m. and at 9:30 a.m.
hodyreva [135]

Answer:

Temporary road closure or coffee break

Explanation:

Assume a car started on a trip at 08:00 and the graph below shows the total distance it travelled every half-hour.

We see that after 1 h (at 09:00) the car was a certain distance from the start.

A half-hour later (at 09:30) the car was still at the same distance.

The car was stopped.

There may have been a bad traffic accident that closed the road or the driver may have stopped for a quick cup of coffee.
