What is Chemical Equilibrium or Ionic Equilibrium ?
Ionic Equilibrium is about the ration of rate of backward and forward reaction for Ions only, while Chemical Equilibrium is about the ration of rate of backward and forward reaction for other types (molecules of Liquid solution & gases) When the reaction involves ions, we go for Ionic Equilibrium constant, and if not, then we go for Chemical Equilibrium Constant
What is Limit, Continuity & Differentiability ?
Limit is calculated which when function is undefined or indeterminate at particular co-ordinate point, but it can calculated in close proximity position. There are several types of indeterminate and then, ways to find out the value or limit in those proximity Continuity is found out if a function is continuous at particular co-ordinate point, by comparing the value of function is close proximity of co-ordinate point by calculating limit values Differentiability of found out is changes in function value is quite constant for close proximity of co-ordinate point, so that tangent or normal for that function can be calculated

What is a Pointer ?
Pointer is a programming language object which is used to point some value, stored at memory location, pointed by pointer value. Pointer is very helpful when you are dealing with large Array, structures or function having more than one output, because In such cases, you don't need to deal with complete structure, or array size, you just need to use address of those structure or array. Data structure, which is important part of programming world, is all about pointers
