Calcium nitrate and ammonium fluoride react to form calcium fluoride, dinitrogen monoxide, and water vapor. What mass of each substance is present after \( 29.61 \mathrm{~g} \) of calcium nitrate and \( 30.85 \mathrm{~g} \) of ammonium fluoride react completely? g calcium nitrate g ammonium fluoride g calcium fluoride \( g \) dinitrogen monoxide g water Chromium(III) oxide reacts with hydrogen sulfide \( \left(\mathrm{H}_{2} \mathrm{~S}\right) \) gas to form chromium(III) sulfide and water: \[ \mathrm{Cr}_{2} \mathrm{O}_{3}(s)+3 \mathrm{H}_{2} \mathrm{~S}(g) \rightarrow \mathrm{Cr}_{2} \mathrm{~S}_{3}(s)+3 \mathrm{H}_{2} \mathrm{O}(l) \] To produce \( 933 \mathrm{~g} \) of \( \mathrm{Cr}_{2} \mathrm{~S}_{3} \), (a) how many moles of \( \mathrm{Cr}_{2} \mathrm{O}_{3} \) are required? mol (b) how many grams of \( \mathrm{Cr}_{2} \mathrm{O}_{3} \) are required?
