The balanced chemical equation for the decomposition of ammonia is:
2 NH₃ → N₂ + 3 H₂
From the equation, it can be seen that for every 2 moles of ammonia that decompose, 3 moles of hydrogen gas are produced. Therefore, when 2 moles of ammonia decompose, the number of moles of hydrogen gas produced is:
2 moles NH₃ × (3 moles H₂ / 2 moles NH₃) = 3 moles H₂
Therefore, 3 moles of hydrogen gas are produced.
When 2 moles of ammonia (NH₃) decomposes into nitrogen gas (N₂) and hydrogen gas (H₂), how many moles of hydrogen gas are produced?
1 mole
2 moles
3 moles
4 moles
