Question

NH3 + ___02 → _NO2+ ___ H2O bepro

Answer 1

The Balancing of the reaction will be done as follows:

The reaction : NH₃ + O₂$\rightarrow$ NO₂ + H₂O

Step 1: Balance the Hydrogen atoms

6 on each side (LCM of 2 and 3)

       2 NH₃ + O₂$\rightarrow$ NO₂ + 3 H₂O

Step 2: Balance the Nitrogen atoms

2 NH₃ + O₂$\rightarrow$2 NO₂ + 3 H₂O

Step 3: Balance the Oxygen atoms (always this should be the last step)

Since There are 4 + 3 = 7 Oxygen on the right side,

There should be (7/2) moles of oxygen on the left side.

2 NH₃ + (7/2) O₂$\rightarrow$ 2 NO₂ + 3 H₂O

Multiplying by 2 , to bring all the coefficients in whole number:

4 NH₃ + 7 O₂$\rightarrow$4 NO₂ + 6 H₂O         ... Answer
