Question

When 2 moles of ammonia (NH₃) decomposes into nitrogen gas (N₂) and hydrogen gas (H₂), how many moles of hydrogen gas are produced?

Answer 1

When 2 moles of ammonia (NH3) decomposes into nitrogen gas (N2) and hydrogen gas (H2), the balanced chemical equation for the reaction is:

2 NH3 -> N2 + 3 H2

Therefore, 3 moles of hydrogen gas (H2) are produced for every 2 moles of ammonia (NH3) that decomposes.
