Answer 1

15 mole of hydrogen required listen for 1 mole of ammonia 3mole of hydrogen is required so....


please tap thank you for answer

Answer 2

Answer: 15 moles of hydrogen are required

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

The balanced reaction for synthesis of ammonia is:

$N_2(g)+3H_2(g)\rightarrow 2NH_3(g)$

According to stoichiometry :

2 moles of ammonia is produced by =  3 moles of hydrogen

Thus 10 moles of ammonia is produced by =$\frac{3}{2}\times 10=15moles$ of hydrogen

Thus 15 moles of hydrogen are required to produce 10 moles of ammonia.
