Select the correct answer. 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.

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
