Final answer:
To determine the limiting reactant in a reaction between NH₃ and CuO, you must first write the balanced chemical equation. Calculate the molar masses, then calculate the moles of each reactant, and use stoichiometry to find which reactant yields less Cu and is therefore the limiting reactant.
Step-by-step explanation:
To determine the limiting reactant and the mass of Cu formed from the reaction of NH₃ and CuO, you must first write the balanced equation for the reaction. While the equation isn't provided, it will typically take the form of a combination of NH₃ and CuO, resulting in Cu and other products. To find the limiting reactant, calculate the number of moles of each reactant, taking their molar masses into account.
The following steps will help:
- Calculate the molar mass of NH₃ and CuO.
- Determine the number of moles for each reactant using the provided masses.
- Using the stoichiometry of the balanced equation, calculate the theoretical yield of Cu from each reactant.
- The reactant that produces the lesser amount of Cu will be the limiting reactant.
Regarding the specific reaction mentioned, additional information, such as the balanced chemical equation, would be necessary to perform the calculations and determine the limiting reactant and the theoretical yield of Cu. Without it, you can approach the problem conceptually as illustrated but cannot obtain a numerical answer.
