Option 1:

This option states that if the reaction is carried to completion, all the 02 (g) is consumed. In this reaction, we have 1.0 mol of O2 (g) reacting with 1.0 mol of NH3 (g), and the balanced equation shows that 4 moles of NH3 are produced. However, nothing is mentioned about the consumption of O2. Therefore, this option is valid because if the reaction goes to completion, it means that all the reactants are consumed, including the O2.

Option 2:

This option states that if the reaction is carried to completion, 4.0 mol of NO (g) is produced. However, the balanced equation shows that for every 2 moles of NH3, 4 moles of NO are produced. Since we only have 1.0 mol of NH3, we can only produce 2.0 mol of NO. Therefore, this option is incorrect.

Option 3:

This option states that if the reaction is carried to completion, 1.5 mol of H2O (g) is produced. However, the balanced equation shows that for every 4 moles of NH3, 6 moles of
