Question

Ammonia + oxygen = nitric oxide + water balance chemical equation

Answer 1

4NH3+ 5O2---> 4NO + 6H2O

Answer 2

$\bold{AMMONIA}$

Ammonia is a pungent smelling gas with alkaline nature. It reacts with oxygen with two ways :--

◼Burning in presence of oxygen

When dry ammonia gas is passes over in the container containing oxygen it donot ignite but burns in atmosphere with greenish yellow flame forming nitrogen and water.

$4NH_3 \longrightarrow 2N_2 + 6H_2O$

◼When ammonia reacts with oxygen in presence of catalyst.

When ammonia gas and oxygen is passed over platinum which acts as a catalyst,

▶ A colourless gas is formed which is nitric oxide which on further oxidation gives a reddish brown gas nitrogen dioxide.

▶Water is formed

▶Since, the reaction is exothermic platinum emits reddish glow

$4NH_3 + 5O_2 \xrightarrow{Pt } 4NO + 6H_2O + \Delta$
