How many moles of NH₃ can be produced from 4.81 moles of nitrogen in the following reaction:
makkiz [27]

Answer:

9.62moles of NH₃

Explanation:

Given parameters:

Number of moles of nitrogen  = 4.81moles

Unknown:

Number of moles of  NH₃ = ?

Solution:

To solve this problem, we need to establish a balanced reaction equation:

            N₂  +  3H₂  →  2NH₃

Now, we can solve the problem by working from the known to the unknown.

          1 mole of N₂ produced 2 moles of NH₃

         4.81moles of N₂ will produce 2 x 4.81  = 9.62moles of NH₃

Match the following equation with the type of chemical reaction. Question 6 options: H2 + O2 ---> H2O HBr ---> H2 + Br2 HC
kenny6666 [7]
Hello there!

1. Synthesis: 2H₂ + O₂ → 2H₂O
2. Decomposition: 2HBr → H₂ + Br₂
3. Single-Replacement: 2Al + 3H₂SO₄ → 3H₂ + Al₂(SO₄)₃
4. Double-Replacement: 2HCl + 2NaOH → 2H₂O + 2NaCl
5. Combustion: 2C₂H₆ + 7O₂ → 6H₂O + 4CO₂

I hope this helps!
