The rate of the backward reaction increases
Explanation:
It is evident that if the reaction is left to proceed spontaneously, the forward reaction is favored because it results in a decrease in pressure in the system (The total reactants have 5 moles and the products have 3 in total).
Increasing H₂O concentration is then reaction, therefore, stymies the forward reaction and favors the reserves reaction. This is because the reverse reaction will lead to reduced pressure. 
 
        
             
        
        
        
Answer:
Compounds formed from non-metals consist of molecules. 
Explanation:
 The atoms in a molecule are joined together by covalent bonds. These bonds form when atoms share pairs of electrons.

When the reactant is single compound before the reaction and become more than single compound after reaction is called decomposition reaction
        
                    
             
        
        
        
the answer is magnetic separation, not sedimentation separation
