Question

Looking at the following equation, which is the correct order of coefficients?

NH3 + O2 --> NO + H2O

Answer 1

Answer: The correct order of coefficients is 4, 5, 4 and 6.

Step-by-step explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.

The balanced chemical equation is:

`4NH_3+5O_2\rightarrow 4NO+6H_2O`

The correct order of coefficients is 4, 5, 4 and 6.
