2 NH3 + 3 CuO g 3 Cu + N2 + 3 H2O In the above equation how many moles of N2 can be made when 13 moles of CuO are consumed?

From 13 moles of CuO 4.3 moles of N₂ are formed.

Given:

Number of moles of CuO react = 13 mol

To find:

Number of moles of N₂ formed = ?

The balanced chemical equation:

2NH₃ + 3CuO → 3Cu + N₂ + 3H₂O

On comparing the moles of CuO and N₂.

CuO : N₂

3 : 1

13 : 1/3*13 = 4.3 mol

Thus, from 13 moles of CuO 4.3 moles of N₂ are formed.

From 13 moles of CuO 4.3 moles of N₂ are formed

Explanation:

Given data:

Number of moles of N₂ formed = ?

Number of moles of CuO react = 13 mol

Solution:

Chemical equation:

2NH₃ + 3CuO     →    3Cu + N₂ + 3H₂O

Now we will compare the moles of CuO and N₂.

                CuO         :              N₂

                   3            :              1

                   13          :           1/3×13 = 4.3 mol

Thus, from 13 moles of CuO 4.3 moles of N₂ are formed.
