An example of a reversible reaction is (a) \( Pb \left( NO _{3}\right

1.	An example of a reversible reaction is (a) \( Pb \left( NO _{3}\right)_{2}( aq )+2 Nal ( aq )= Pbl _{2}( s )+2 NaNO _{3}( aq ) \) (b) \( AgNO _{3}( aq )+ HCl ( aq )= AgCl ( s )+ HNO _{3}( aq ) \) (c) \( 2 Na ( s )+ H _{2} O ( l )=2 NaOH ( aq )+ H _{2}( g ) \) (d) \( KNO _{3}( aq )+ NaCl ( aq )= KCl ( aq )+ NaNO _{3}( aq ) \)
Answer» KNO₃(aq) + Nacl(aq) \(\rightleftharpoons\) kcl (aq) + NaNO₃(aq) is a reversible reaction.

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil.
