What is the balanced reaction between NO2 and Lime water?

Answer 1
#NO_2# is called mixed anhydride.as it forms two acids #HNO_3 and HNO_2# when treated with water.
#2NO_2+H_2O->HNO_3+HNO_2#
So when treated with a base #Ca(OH)_2#, this will form two types of Ca-salt of #HNO_3 and HNO_2# acid produced.

The equation that is balanced will be

#2Ca(OH)_2+4NO_2-> Ca(NO_3)_2 + Ca(NO_2)_2+2H_2O#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
