This map shows the amount of groundwater (GW) in parts of Pakistan. Farmers in Pakistan once relied on rivers and canals for their water supply, but as cities expanded and populations grew, more farmers used groundwater for their crops. When this map was made, there were no
laws restricting how many wells could be built in Pakistan to remove groundwater.
What would be the best solution to help Pakistan conserve their water supply?
A. Increase the number of groundwater wells in all three regions.
B. Build more wells in region 3, and restrict building in all other regions.
C. Pass laws restricting well building in region 1, but increase wells in regions 2 and 3.
D. Pass laws restricting all wells, with the fewest restrictions in Region 1.

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.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
