Xenon hexafluoride was one of the first noble gas compounds synthesized. The solid reacts rapidly with the silicon dioxide in glass or quartz containers to form liquid \( \mathrm{XeOF}_{4} \) and gaseous silicon tetrafluoride. What is the pressure in a \( 1.00-\mathrm{L} \) container at \( 25^{\circ} \mathrm{C} \) after 6.27 g of xenon hexafluoride reacts? (Assume that silicon tetrafluoride is the only gas present and that it occupies the entire volume.) Round your answer to 3 significant figures. Note: Reference the Fundamental constants table for additional information.

Calcula la solubilidad molal del dióxido de carbono en agua a \( 298^{\circ} \mathrm{K} \) y una presion de \( \mathrm{CO}_{2} \) de \( 3.3 \times 10^{-4} \mathrm{~atm} \), que corrsponde a la presión parcial del \( \mathrm{CO}_{2} \)

4. (Aman-RJ) Os corais fixam-se sobre uma base de carbonato de cálcio \( \left(\mathrm{CaCO}_{3}\right) \), produzido por eles mesmos. O carbonato de cálcio em contato com a água do mar e com o gás carbônico dissolvido pode estabelecer o seguinte equilibrio químico para a formaçảo do hidrogenocarbonato de cálcio: \( \mathrm{CaCO}_{3}(\mathrm{~s})+\mathrm{CO}_{2}(\mathrm{~g})+\mathrm{H}_{2} \mathrm{O}(\ell) \rightleftharpoons \mathrm{Ca}\left(\mathrm{HCO}_{3}\right)_{2}(\mathrm{aq}) \). Considerando um sistema fechado onde ocorre o equilibrio químico da reaçăo mostrada acima, assinale a alternativa correta. a) Um aumento na concentração de carbonato causará um deslocamento do equilibrio no sentido inverso da reacāo nosentido dos reagentes.
