Why is it better to only dehydrate one hand at a time

I don't think it works like that dawg

Well if your talking about what I think its because it will lead to dirty and unproperly cleaning and care of nails. Also here's some other titles that may help you

(“One of the most common mistakes nail technicians make in nail preparation is … is not being used to clean, dehydrate and prep the nails before application)

(Most experts recommend that you use Nail Dehydrators and Non-Acid Based Primers. They are generally safer and less harsh on your nails.)

can you list the answers so i can answer

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.
