Final answer:
To find the number of moles of ammonia produced from 4.0 moles of nitrogen, we use the balanced chemical equation N2 + 3H2 → 2NH3. From the given mole ratio, 1 mole of N2 produces 2 moles of NH3, hence 4.0 moles of N2 would produce 8.0 moles of NH3.
Step-by-step explanation:
The question pertains to a chemical reaction where nitrogen (N2) reacts to form ammonia (NH3). To determine how many moles of ammonia will be produced from 4.0 moles of nitrogen, we need to consider the balanced chemical equation for the synthesis of ammonia, which is:
N2 + 3H2 → 2NH3
From this equation, we can see that 1 mole of nitrogen gas would produce 2 moles of ammonia. Therefore, if we have 4.0 moles of nitrogen reacting, we would expect to produce:
4.0 moles N2 × (2 moles NH3 / 1 mole N2) = 8.0 moles NH3
The balanced chemical equation and the mole ratio are essential in calculating the amount of product formed in a chemical reaction.
