Some acids are capable of drawing water out of an object. this process is called

A double replacement reaction do not take place if a solution of sodium hydrogen carbonate is added to a solution of sodium chloride.

NO reaction occur.

Explanation:

Double replacement Reaction  : A reaction in which positive and negative ions of two different compound exchange to form new compounds.

This is also called metathesis reaction.

For Example :

Here Na+ and Sr2+ has exchanged

Cl- and SO4(2-) has exchanged their places.

So , Requirement of Double displacement reaction is :

Their should be salts of different cation and anion

=  sodium hydrogen carbonate =Na+ cation

and HCO3 - anion

NaCl = Sodium Chloride = Na+ cation and Cl- anion

In both the reacts the cation is : Na+

So No-exchange of ions occur .

No- double displacement reaction.

The reality is , this reaction can't occur at all. It can neither be acid-base nor Redox Reaction

So ,
