**Question:**Nitrogen gas can be prepared by passing ammonia over copper(II) oxide, and the other products are copper metal and water vapor. If a sample containing 8.63 moles of \( \text{NH}_3 \) is reacted with excess copper(II) oxide, how many grams of \( \text{N}_2 \) will be formed?---**Explanation:**The problem involves a chemical reaction where ammonia (\( \text{NH}_3 \)) reacts with copper(II) oxide to produce nitrogen gas (\( \text{N}_2 \)), copper metal, and water vapor. The task is to determine the amount of nitrogen gas produced in grams when a specific amount of ammonia is used.1. **Balanced Chemical Equation:** The balanced chemical equation for the reaction is necessary to determine the stoichiometric ratios between reactants and products.2. **Mole Ratio:** Use the balanced equation to identify the mole ratio between ammonia and nitrogen gas.3. **Calculation:** - Calculate the moles of \( \text{N}_2 \) produced using the mole ratio. - Convert moles of \( \text{N}_2 \) to grams using the molar mass of nitrogen gas.4. **Result:** Present the final result in grams.

The balanced reaction is: 2NH3 + 3CuO → N2 + 3Cu + 3H2O

Nitrogen gas can be prepared by passing ammonia over copper(II) oxide, and the other products are copper metal and water vapor. If a sample containing 8.63 moles of NH3 is reacted with excess copper(I) oxide, how many grams of N2 will be formed?

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
