Answer:

A variable or alteration to one part that affects an entire system

Explanation:

Change in literal sense means the occurrence of some alteration or difference in a given object/situation/person etc.
When we talk about physical and natural systems, then one can say that if a system shifts from one state to another then it has changed.
The shift in the state means an alteration in its physical or chemical properties that occur in such a way that it causes a difference between the original state of the system to the final state.
For example, if in a human body which is a natural system if the blood pressure drops then we can say that there is a change that took place.

Answer:

$2Cl^{-}_{(aq)} + 2K^{-} _{(aq)} = 2KClx_{(aq)}$

Explanation:

The reaction is a precipitation reaction. In other words, the two aqueous solutions react to give the solid salt, potassium chloride (KCl) in this case.

$SrCl_{2} _{(aq)} + K_{2}SO_{4} _{(s)} = SrSO_{4} _{(aq)} + 2KCl_{(s)}$
