How do you complete nh3 plus o2 plus h2o equals Hno3?

Answer 1

NH3 + O2 + H20 = HNO3 + 2H2

Basically, on the left you have 1 N, 3 O and 5 H atoms. On the right, you have 1 H, 1 N and 3 O atoms - leaving 4 H atoms doing nothing. Since a molecule of Hydrogen has 2 atoms, you need 2 atoms to balance the equation.

Answer 2

The balanced chemical equation for the reaction NH3 + O2 + H2O → HNO3 is: 4 NH3 + 5 O2 → 4 HNO3 + 6 H2O. Balancing chemical equations involves adjusting the coefficients in front of each compound to ensure that the number of atoms for each element is the same on both sides of the equation.
