Use the unbalanced equation NH3 + O2 = NO + H2O, what is the mole ratio between NH3 and NO

The first thing that needs to be done in order to answer the question above is to balance first the chemical equation by seeing to that the number of moles of a certain element on the reactant side is equal to the number of moles in the product side. 4NH3 + 5O2  4NO + 6H2O The mole fraction between the NH3 and NO is therefore 4:4 or 1:1.

Answer: The mole ratio between [tex]NH_3[/tex] and [tex]NO[/tex] is, 1 : 1

Explanation:

The given unbalanced chemical reaction is,

[tex]NH_3+O_2\rightarrow NO+H_2O[/tex]

This is an unbalanced chemical reaction because in this reaction the number oxygen and hydrogen atoms are not balanced on both side.

In order to balance the chemical reaction, the coefficient 4 is put before [tex]NH_3[/tex], coefficient 3 is put before [tex]O_2[/tex], coefficient 4 is put before [tex]NO[/tex] and coefficient 2 is put before [tex]H_2O[/tex].

The balanced chemical reaction will be,

[tex]4NH_3+3O_2\rightarrow 4NO+2H_2O[/tex]

From the balanced chemical reaction we conclude that,

The mole ratio of [tex]NH_3:O_2:NO:H_2O[/tex] are 4 : 3 : 4 : 2

The mole ratio of [tex]NH_3:NO[/tex] are 4 : 4 or 1 : 1

Therefore, the mole ratio between [tex]NH_3[/tex] and [tex]NO[/tex] is, 1 : 1
