Get started for freeWrite plausible half-equations and a balanced oxidation-reduction equation for the disproportionation of \(\mathrm{XeF}_{4}\) to \(\mathrm{Xe}\) and \(\mathrm{XeO}_{3}\) in aqueous acidic solution. Xe and \(\mathrm{XeO}_{3}\) are produced in a 2: 1 mol ratio, and \(\mathrm{O}_{2}(\mathrm{g})\) is also produced.
Write an appropriate formula for each of the following: (a) hydroxylamine; (b) calcium hydrogen phosphate; (c) lithium nitride.
A 25.0 L sample of a natural gas, measured at \(25^{\circ} \mathrm{C}\). and 740.0 Torr, is bubbled through \(\mathrm{Pb}^{2+}(\mathrm{aq}),\) yielding \(0.535 \mathrm{g}\) of \(\mathrm{PbS}(\mathrm{s}) .\) What mass of sulfur can be recovered per cubic meter of this natural gas?
Provide an explanation for the inability of \(\mathrm{O}_{2}\) to react directly with xenon.
Various thermochemical cycles are being explored as possible sources of \(\mathrm{H}_{2}(\mathrm{g}) .\) The object is to find a series of reactions that can be conducted at moderate temperatures (about \(500^{\circ} \mathrm{C}\) ) and that results in the decomposition of water into \(\mathrm{H}_{2}\) and \(\mathrm{O}_{2} .\) Show that the following series of reactions meets these requirements. $$\begin{aligned}\mathrm{FeCl}_{2}+\mathrm{H}_{2} \mathrm{O} \longrightarrow \mathrm{Fe}_{3} \mathrm{O}_{4}+\mathrm{HCl}+\mathrm{H}_{2} \\\\\mathrm{Fe}_{3} \mathrm{O}_{4}+\mathrm{HCl}+\mathrm{Cl}_{2} & \longrightarrow \mathrm{FeCl}_{3}+\mathrm{H}_{2} \mathrm{O}+\mathrm{O}_{2} \\\\\mathrm{FeCl}_{3} \longrightarrow & \mathrm{FeCl}_{2}+\mathrm{Cl}_{2}\end{aligned}$$
