4N2 and 4H2

Answer 1

To determine which combination of molecules will produce ammonia with no leftovers, we need to analyze each option based on the balanced chemical equation:

1N₂ + 3H₂ → 2NH₃

This means that for every 1 molecule of nitrogen (N₂), 3 molecules of hydrogen (H₂) are needed to produce 2 molecules of ammonia (NH₃).

Now let's check each response:

1. 2N₂ and 6H₂:

   • Nitrogen: 2 N₂ → 2 x 1 = 2 N₂
   • Hydrogen: 6 H₂ → 6 / 3 = 2 N₂ needed
   • This combination perfectly matches the equation, producing 4 NH₃ (no leftovers).

2. 8N₂ and 4H₂:

   • Nitrogen: 8 N₂ → 8 x 1 = 8 N₂
   • Hydrogen: 4 H₂ → 4 / 3 = 1.33 N₂ needed (which is not a whole number)
   • This combination does not match the equation (leftovers from nitrogen).

3. 5N₂ and 6H₂:

   • Nitrogen: 5 N₂ → 5 x 1 = 5 N₂
   • Hydrogen: 6 H₂ → 6 / 3 = 2 N₂ needed (leftover hydrogen).
   • This combination does not match the equation (leftovers).

4. 4N₂ and 4H₂:

   • Nitrogen: 4 N₂ → 4 x 1 = 4 N₂
   • Hydrogen: 4 H₂ → 4 / 3 = 1.33 N₂ needed (leftover hydrogen).
   • This combination does not match the equation (leftovers).

The only combination that produces ammonia with no leftovers is 2N₂ and 6H₂.
