The Haber process produces ammonia commercially. It is represented by the equation N2(g) 3H2(g) --> 2NH3(g) To completely convert 9.0 mol hydrogen gas to ammonia gas, how many moles of nitrogen are required

3 moles

Explanation:

The balanced equation for the reaction is given below below:

N2(g) 3H2(g) --> 2NH3(g)

From the balanced equation above,

1 mole of N2 required 3 moles of H2.

Therefore, Xmol of N2 will require 9 moles of H2 i.e

Xmol of N2 = 9/3

Xmol of N2 = 3 moles

From the calculations made above, 3 moles of nitrogen (N2) is needed to completely convert 9.0 mol hydrogen gas(H2) to ammonia gas (NH3)

pure substance: iron,copper

impure substance: water,charcoal

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
