Nitrogen and hydrogen react together to form ammonia according to the equation: ___N₂(g)+ ___H₂(g)$\rightarrow$___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 required 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.
