you have a pool in your backyard. you need to make sure it maintains a certain pH so that it is safe to swim in. how would you determine the amount of muriatic acid (HCl) you need to add in order to keep your pool safe

i think   the answer is c hope i'm right

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.

50.23 i believe is correct but don't quote me on that.
