Get started for freeWhat role does each of the following materials play in the chemical processes that occur in a blast furnace: (a) air, (b) limestone, (c) coke (d) water? Write balanced chemical equations to illustrate your answers.
Use the thermodynamicquantities given in Appendix C to calculate \(\Delta G^{\circ}, \Delta H^{\circ}\), and \(\Delta S^{\circ}\) for the reaction corresponding to roasting of \(\mathrm{PbO}\) in a CO atmosphere (Equation 23.5). Approximate the thermodynamic quantities of \(\mathrm{Pb}(I)\) using the thermodynamic properties of \(\mathrm{Pb}(s)\). Is this reaction spontaneous at \(25^{\circ} \mathrm{C}\) under standard conditions? Is it exothermic or endothermic?
The thermodynamic stabilities of the three complexes \(\mathrm{Zn}\left(\mathrm{H}_{2} \mathrm{O}\right)_{4}^{2+}, \mathrm{Zn}\left(\mathrm{NH}_{3}\right)_{4}^{2+}\), and \(\mathrm{Zn}(\mathrm{CN})_{4}^{2-}\) increase from the \(\mathrm{H}_{2} \mathrm{O}\) to the \(\mathrm{NH}_{3}\) to the \(\mathrm{CN}^{-}\) complex. How do you expect the reduction potentials of these three complexes to compare?
A sample containing \(\mathrm{PbSO}_{4}\) is to be refined to \(\mathrm{Pb}\) metal via calcination, followed by roasting. (a) What volatile product would you expect to be produced by calcination? (b) Propose an appropriate atmosphere to accompany the roasting. (c) Write balanced chemical equations for the two steps.
