The balanced chemical equation for the reaction between ammonia (NH3) and oxygen (O2) is:

4 NH3 + 3 O2 → 2 N2 + 6 H2O

According to the equation, it takes 3 moles of O2 to fully react with 4 moles of NH3. This can be simplified to a molar ratio of O2 to NH3 of 3:4.

To find how many moles of O2 are needed to fully react with 11 moles of NH3, we can set up a proportion using the molar ratio:

3/4 = x/11

Solving for x, we get:

x = 33/4

x ≈ 8.25

Therefore, approximately 8.25 moles of O2 are needed to fully react with 11 moles of NH3.
