Seawater, which covers the majority of the earth, is composed primarily of molecules of H2O and equal numbers of Na ions and Cl- ions. Suppose we have a thoroughly mixed solution (containing these species only) at 25oC. How many components and how many phases are in such a system?

Explanation:

Species present are , and . Now, we will calculate the number of componenets present as follows.

                C = n - E

where,   E = number of independent equations

              n = number of phases present

Therefore, we will calculate the number of components as follows.

                        C = 3 - 1

                            = 2

Since, sodium chloride (NaCl) will tend to form a homogeneous mixture in water. Therefore, phase will be equal to 1.

Therefore, it means that there are two components present in one phase.  

The answer is C) argue that the overall experience of human perception is greater than the sum of its parts.

Explanation:

Gestalt psychologists such as Max Wertheimer and Wolfgang Köhler argue that the overall experience of human perception is greater than the sum of its parts: Gestalt principles believe that all forms of knowledge, complex/abstract ideas or great experiences can be broken down into bits or simple constituents or elements; generally speaking, a complex knowledge or idea consists of simple ideas.
