Nitrogen and hydrogen react together to form ammonia according to the equation: ___N₂(g)+ ___H₂(g)→ ___NH₃(g)(unbalanced)Balance the equation, and determine how many grams of hydrogen would be required to react with 25.2 g of nitrogen.

Question

Quizplus · Accepted Answer

The balanced equation is N₂ + 3H₂ → 2NH₃. The molar mass of N₂ is 28.02 g/mol, so 25.2 g of N₂ is 0.9 mol. According to the balanced equation, 3 moles of H₂ are needed for every mole of N₂, so 0.9 mol of N₂ requires 2.7 mol of H₂. The molar mass of H₂ is 2.02 g/mol, so 2.7 mol of H₂ is 5.45 g.
