Consider the reaction between hydrazine, N₂H₄, and hydrogen peroxide, H₂O₂, as shown in the unbalanced reaction below:
__ N₂H₄ + __ H₂O₂→__ N₂ + __ H₂O (unbalanced reaction) How many grams of N₂H₄ would be required to produce 20.0 grams of water?

Question

Quizplus · Accepted Answer

First, balance the chemical equation: N2H4 + 2H2O2 → N2 + 4H2O. To produce 20.0 g of H2O (about 1.11 moles), 0.2775 moles of N2H4 are needed (since 1 mole of N2H4 produces 4 moles of H2O). The molar mass of N2H4 is approximately 32.05 g/mol, so 0.2775 moles of N2H4 is about 8.89 g, which rounds to 8.90 g.
