Question

составить электронный баланс реакции NH3+O2 → N2+H2O

Answer 1

4NH3+3O2 → 2N2+6H2O

2N(3-)-6e=N2(0)    |6e|4

O2+4e=2O(2-)       |4e|6

Answer 2

NH3+O2=N2+H2O 
2NH3 - 6e=N2 +6H+ 
O2+4e+4H+=2H2O 
3O2+12H+ + 4NH3=6H2O+2N2+12H+ 
4NH3+3O2=2N2+6H2O 

Answer 3

Balancing the Reaction Equation for NH3 + O2 → N2 + H2O

To balance the chemical reaction equation for NH3 + O2 → N2 + H2O, we need to ensure that the same number of each type of atom is present on both sides of the equation.

The unbalanced equation is: NH3 + O2 → N2 + H2O

To balance it, we can follow these steps:

1. Balance the non-hydrogen and non-oxygen atoms first. 2. Balance the hydrogen atoms next. 3. Balance the oxygen atoms last.

Balancing Steps:

1. Balance Nitrogen (N): - There are 1 N atom on the left and 2 N atoms on the right. To balance N, we put a coefficient of 2 in front of NH3. - The equation becomes: 2NH3 + O2 → N2 + H2O

2. Balance Hydrogen (H): - There are 6 H atoms on the left and 2 H atoms on the right. To balance H, we put a coefficient of 3 in front of H2O. - The equation becomes: 2NH3 + O2 → N2 + 3H2O

3. Balance Oxygen (O): - There are 2 O atoms on the left and 6 O atoms on the right. To balance O, we put a coefficient of 3 in front of O2. - The final balanced equation is: 4NH3 + 5O2 → 4N2 + 6H2O

So, the balanced chemical equation for the reaction NH3 + O2 → N2 + H2O is: 4NH3 + 5O2 → 4N2 + 6H2O
