I believe the answer is a definition. 
        
             
        
        
        
The reaction N2O4 (g) <--> 2NO2 (g) is endothermic, meaning that it consumes heat to move towards formation of the products.
According to Le Chatelier's Principle, therefore, if heat is added, more product (NO2) will be produced, and equilibrium would shift towards the right side. This is choice 3.

A.)Neutral. Since amount of protons and electron are equal and amount of protons cannot be changed so it is stable or neutral.
 
        
                    
             
        
        
        
Answer:
hypertonic solution
Explanation:
Hypertonic solution - 
It is the solution, with more amount of solute than the solvent , is known as hypertonic solution. 
Now, is some substance is immersed in such solution , the substance gets shrinked , because , the solvent from the substance moves out of it and moves to the hypertonic solution. 
Hence, the pickles gets shrinked up , as they put in a hypertonic solution.
