Identify the chemical reaction Below:
KOH + AlCl3 + AlCl3+ KCI

Double displacement reaction

Explanation:

Given expression:

          KOH   +    AlCl₃   →   Al(OH)₃  +  KCl

The reaction shown above is a double displacement reaction or double decomposition or double replacement reaction. This type of reaction involves an actual exchange of partners to form new compounds.

For example:

         AB + CD  →   AD + CB

Such reactions are driving by one of the following factors:

formation of an insoluble compoundformation of water or any other non-ionizing compoundliberation of a gaseous product

Enormous O unpredictability is in reference to the most exceedingly terrible conceivable development rate of the calculation. So O(N log N) implies that it will never keep running in some time more terrible than O(N log N). So in spite of the fact that Al's calculation scales superior to Bob's quadratic algo, it doesn't really mean it is better for ALL info sizes. 
Maybe there is critical overhead in building up it, for example, making a lot of clusters or factors. Remember that even an O(N log N) calculation could have 1000 non settled circles that official at O(N) and still be viewed as O(N log N) the length of it is the most exceedingly awful part.
