14 g of nitrogen will react with ________ g of oxygen. 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 approximately 28 g/mol, so 14 g represents 0.5 moles. Using the mole ratio from the equation, we can calculate that 1 mole of N₂ requires 2 moles of O₂, or approximately 64 g of O₂ (2 moles of O₂ at a molar mass of 32 g/mol). Therefore, 14 g of nitrogen will react with (64 g/1 mole) x (0.5 moles) = 32 g of oxygen (Answer choice C).

14 G of Nitrogen Will React with ________ G of Oxygen
