14 g of nitrogen will yield ________ g of nitrogen dioxide. N₂ + 2 O₂ → 2 NO₂

Question

Quizplus · Accepted Answer

According to the balanced chemical equation, 1 mole of N₂ reacts with 2 moles of O₂ to produce 2 moles of NO₂. The molar mass of N₂ is 28 g/mol, so 14 g of N₂ is equal to 0.5 moles. Using the mole ratio from the balanced equation, 0.5 moles of N₂ will react with 1 mole of O₂ to produce 1 mole of NO₂. The molar mass of NO₂ is 46 g/mol, so 1 mole of NO₂ is equal to 46 g. Therefore, 0.5 moles of NO₂ (which is the amount produced in the reaction) is equal to 23 g. Therefore, the answer is B.

14 G of Nitrogen Will Yield ________ G of Nitrogen
