Question

write the balanced equation when ammonia is burnt in air​

Answer 1

When ammonia is burnt in air , the products formed are water and nitrogen monoxide.
NH4 + O2 = H2O + NO

Couldn’t find arrow , so I used = in the place of arrow .

Answer 2

Answer and Explanation:

$\blacksquare$ Chemical equations are balanced to make law of conservation of mass true

That is,

Total mass on LHS = Total mass of RHS

Atoms of an element should be equal in LHS and RHS

$\blacksquare$ Ammonia when burnt in air produces nitric oxide and water vapour

$\blacksquare$ Ammonia when it is burning in air is actually reacting with the oxygen present in air

$\blacksquare$ The balanced chemical equation is given by :

$\huge \text {\boxed{4NH_3 + 5O_2 \longrightarrow 4NO + 6H_2O}}$
