The important method for the fixation of nitrogen is

The correct statement$(s)$ related to oxoacids of phosphorus is(are):
$(A)$ Upon heating,$H_3PO_3$ undergoes disproportionation reaction to produce $H_3PO_4$ and $PH_3$.
$(B)$ While $H_3PO_3$ can act as a reducing agent,$H_3PO_4$ cannot.
$(C)$ $H_3PO_3$ is a monobasic acid.
$(D)$ The $H$ atom of the $P-H$ bond in $H_3PO_3$ is not ionizable in water.

Which reaction does not produce ammonia?

Why does nitrogen show catenation properties less than phosphorus?

Sodium nitrite with hydrochloric acid gives water along with two nitrogen oxides. They are

The products formed by complete hydrolysis of $PCl_3$ are
