Two solutions a and b are separated by a membrane, which is permeable to water but not salts. solution a is a 2% nacl solution, while solution b is a 3% nacl solution. which will occur?

Water of solution A will go through membrane until solution B.

Explanation:

That phenomenon occurs by mass transfer.

Mass transfer is the movement from a location to another that occurs when you have mass gradient. In a membrane with different concentration solutions the system will try to equal both concentrations.

In the problem, Solution B is more concentrated than A. Thus, water will transport from solution A to solution B increasing concentration of A and decreasing concentration of B until the system stay in equilibrium.

I hope ot helps!

gravity causes stares to cluster i think so

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
