Question

Copper reacts with nitric acid to produce copper nitrate, nitrogen dioxide gas, and water. Cu(s) + 4 HNO $_{3}$ (aq) ${\rightarrow}$ Cu(NO $_{3}$ ) $_{2}$ (aq) + 2 NO $_{2}$ (g) + 2 H $_{2}$ O(l) If you have 0.60 moles of Cu and the reaction goes to completion, how many moles of HNO $_{3}$ are needed to produce 1.2 moles of NO $_{2}$ ?

Answer 1

1. The reaction is Cl(s) + 4HNO3(aq)-CUINQ2 (aq) + 2 N02 (3) +244 060 From the data I mole che reach with 4 mole Hng and produce 2 mol NO2 Given of moles of all Produced 1.2 moles of New How much Hng required 1 mole cu reacts with it mole HNO out mole cu reacts with x mole of HNO₂.
