Question: In the reaction 3H2 + N2 → 2NH3, how many moles of nitrogen are required to produce 6 moles of ammonia?

Options:

Correct Answer: 3 moles

Solution:

According to the stoichiometry, 2 moles of NH3 require 1 mole of N2. Therefore, 6 moles of NH3 will require 3 moles of N2.

In the reaction 3H2 + N2 → 2NH3, how many moles of nitrogen are required to produce 6 moles of ammonia?

In the reaction 3H2 + N2 → 2NH3, how many moles of nitrogen are required to produce 6 moles of ammonia?

Step 1: Look at the balanced chemical equation: 3H2 + N2 → 2NH3.
Step 2: Identify the relationship between nitrogen (N2) and ammonia (NH3) in the equation.
Step 3: Notice that 2 moles of NH3 are produced from 1 mole of N2.
Step 4: To find out how many moles of N2 are needed for 6 moles of NH3, set up a ratio based on the equation.
Step 5: Since 2 moles of NH3 require 1 mole of N2, for 6 moles of NH3, you can calculate: (6 moles NH3) * (1 mole N2 / 2 moles NH3).
Step 6: Perform the calculation: 6 moles NH3 * (1/2) = 3 moles N2.
Step 7: Conclude that 3 moles of nitrogen (N2) are required to produce 6 moles of ammonia (NH3).
