D. The reactant in excess is nitric acid and 0.58 L of nitrogen monoxide is formed under standard conditions of pressure and temperature. E. The limiting reagent is bismuth(III) sulfide and 0.29 L of water is formed.
1- Consider the reaction at room temperature of 6.7 g of a pure sample of bismuth (III) sulfide, which is reacted with 75 mL of 2.5 M nitric acid solution, forming elemental sulfur, nitrogen monoxide, nitrate bismuth(III) and water. Indicate which statement is correct:
Alternatives:
A. The limiting reagent is nitric acid, and 0.56 g of nitrogen monoxide is formed.
B. The limiting reagent is bismuth(III) sulfide, and 0.29 L of nitrogen monoxide is formed under standard conditions of pressure and temperature.
C. 0.39 g of nitrogen monoxide is formed and the excess reactant is nitric acid.
D. The reactant in excess is nitric acid and 0.58 L of nitrogen monoxide is formed under standard conditions of pressure and temperature.
E. The limiting reagent is bismuth(III) sulfide and 0.29 L of water is formed.
