From the stoichiometry of the reaction, 1 mole of ammonia, is produced.

<h3>What is reaction?</h3>

A chemical reaction involves the combination of two or more substances to yield products.

The chemical reaction is; Mg3N₂(s) + 6H₂O(1)→ 2NH3(aq) + 3Mg(OH)2(s)

Number of moles of water =  54.0 g/18 g/mol = 3 moles

Now;

6 moles of water produced 2 moles of ammonia

3 moles of water will produce 3 moles * 2 moles/6 moles

= 1 mole of ammonia

water-gas shift membrane reactor(WGSM)

Explanation:

The major component in the processing train for fuel cells is the water-gas shift membrane reactors. Fuel cells offer a very clean and environmental source of energy production. They are usually tagged the future of energy production in the world.

  • Unlike the internal combustion systems that uses fossil fuels to produce energy, the water-gas shift membrane reactor allows for the production of energy using the combination of oxygen and hydrogen in the presence of a catalyst.
  • In the reactor, hydrogen gas is a able to readily diffuse out while the other components are unable to do so.
