\( \mathrm{H}_{3} \mathrm{PO}_{4}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}(1) \rightleftharpoons \mathrm{H}_{2} \mathrm{PO}_{4}^{-}(\mathrm{aq})+\mathrm{H}_{3} \mathrm{O}^{+}(\mathrm{aq}) \) In the reaction stated above, what happens when more \( \mathrm{H}_{2} \mathrm{PO}_{4}^{-}(\mathrm{aq}) \) is added to the solution? View Available Hint(s) The equilibrium shifts to the left, producing more \( \mathrm{H}_{3} \mathrm{PO}_{4}(\mathrm{aq}) \). The equilibrium shifts to the right, creating more \( \mathrm{H}_{3} \mathrm{PO}_{4}(\mathrm{aq}) \). The equilibrium shifts to the right, creating more \( \mathrm{H}_{3} \mathrm{O}^{+}(\mathrm{aq}) \). The equilibrium shifts to the left, producing more \( \mathrm{H}_{3} \mathrm{O}^{+} \).

L'uraninite, ou pechblende, est un minéral de formule chimique \( \mathrm{UO}_{2} \). Les gisements d'uraninite sont datés uniquement entre 3,5 et 2,2 milliards d'années. Its sont utilisés notamment pour extraire l'uranium uti- lisé dans l'industrie nucléaire civile et militaire. Ces gisements se forment dans des milieux réducteurs, c'est-à-dire en absence de dioxygène. Question Expliquer en quoi l'uraninite est un indice de l'évolution de la teneur en dioxygène terrestre.
